More and more people, when choosing thermometers for domestic needs, are choosing an electronic thermometer with a probe. This device greatly simplifies and speeds up the process of measuring temperature in a variety of situations.
Distinctive feature of thermometers with probe
The main feature of these devices is the presence of a probe, which is a kind of thin needle. With its help, when immersed in the studied area, the temperature of the area with which it is in contact is determined.
A thermocouple is located inside the probe, which quickly responds to the environment and transfers data to the instrument housing, where they are converted to digital values and displayed.
Types of probe
The probe itself can be folding, curved or of varying thickness (thin at the end and with a large diameter at the base).
Its connection to the housing can be either direct or using a flexible wire. In some models, communication occurs using a radio signal, in which case the probe is separated from the thermometer body.
An electronic thermometer with a probe, the photo of which is presented in the article, is a model in which the case is directly connected to the probe rod.
Benefits
Let's talk about what the described devices are attracted to:
1. The wide temperature range that the electronic thermometer supports with a probe: -50 to + 300 ° C. This fact significantly expands the area of application of such a device, in contrast to the usual mercury analogues. However, it should be borne in mind that the most reliable maximum indicator that an electronic thermometer with a probe can demonstrate is + 250 ° C.
2. The device is easy to use. It is easy to stick a long thin probe of such a thermometer into the studied object or medium and determine the temperature of the area with which the sensor is in contact. It can be simply leaned against the subject to be determined, for example, to determine the surface temperature.
3. The electronic thermometer with a probe is durable, lightweight and compact. It is convenient to carry it in your pocket or keep it in the glove compartment of the car so that it is always at hand.
4. It acts quickly: just immerse the sensor in the test medium for 5-7 seconds and the display will show the temperature in Celsius or Fahrenheit.
5. Indicators, by the way, are updated every second. If you wish, you can fix them by pressing a special button on the thermometer body.
6. The accuracy of the device ranges from 0.01-0.05 ° C, which allows to determine with maximum certainty the degree of heating or cooling of the investigated substances.
7. The thermometer is easy to use and care for. The main control is carried out using a pair of buttons, and to clean the probe from dirt, just wipe it with a damp cloth and wipe it dry with a cloth.
8. It has a simple battery - a battery (one or two) of type AG13: A76, LR44, SR44W, GP76A. Her work lasts about 2,000-3,000 hours.
Application area
The benefits that an electronic thermometer brings with a probe can hardly be overestimated. It will come in handy if you like to cook deliciously, grow crops or indoor plants, maintain a car or other equipment, do construction and repairs, and do housekeeping.
In addition to these functions, some electronic thermometers have the ability to determine the alcoholicity (strength of drinks), which is useful in brewing and preparing alcohol.
To choose the optimal thermometer for specific purposes, you need to consider the features of different models.
Thermometer electronic TR-101
It is also called a kitchen electronic thermometer with a probe, since this model is often used in cooking. The sensor detects the temperature in liquids, bulk and semi-solid substances. It is convenient to evaluate the readiness of food with it. To do this, the probe is immersed in the thickness of the products and their internal temperature is observed.
For example, you can find out how hot the dish or baby food is, understand whether the bird is ready in the oven, remove the kebab from the fire on time, and also make sure that the pastries inside are not raw. For this, the described device is needed.
An electronic thermometer with a water probe is suitable: it determines its temperature in a pot, bathtub, aquarium or pool.
Management is carried out using the buttons:
- ON / OFF - turn the device on or off.
- HOLD - fix the indicators. By clicking on it, you save the latest temperature readings and can consider it closer if it is inconvenient to do this during measurements. To continue measurements - press HOLD again.
These are the two main buttons that are provided with almost all models of such thermometers. But there may be other controllers for controlling the operation of the device:
- C ° / F ° - allow you to determine the temperature in Celsius or Fahrenheit.
- MAX / MIN - shows the maximum and minimum temperature recorded by the device, however, these values can only be reset by removing the battery from the thermometer, thus rebooting it.
Disadvantages - the inability to determine the temperature inside the oven during cooking, since the thermometer body can melt from high temperatures.
Thermometer with probe on wire
An electronic thermometer with a remote probe is needed for a more comfortable temperature measurement in various conditions:
- Due to the movable sensor attached to the body by means of a flexible wire, it can be placed inside the oven to determine the temperature of the oven itself or stick directly into the baked product.
- With it, it is much more convenient to consider the indicators on the display, this allows a fairly long wire. In addition, such devices are equipped with various mounts for fixing them on a table or in limbo.
- Many models to help housewives are equipped with a timer, a countdown system. Using the program, you can set a certain temperature on the display and insert the probe into the cooking product. When the dish reaches the desired temperature, an electronic thermometer will notify you of this by sounding a beep.
Thermometer and alcohol meter: two in one
The electronic thermometer with the wt-1 probe is also named in the instructions as "electronic thermometer / alcohol meter ETS 223". To accurately identify and identify this model, the inscription wt-1 is present on the case above the display.
Let us immediately explain that it is impossible to measure the strength of a liquid with such a device, because it determines the actual spirituality at an ambient temperature of at least 78 ° C. That is, it is suitable for these purposes only if it is directly connected to the moonshine.
The indicators are displayed in real time. For practical use, two ETC 223 alcohol meters are used: one is connected to a distiller, the second to a distillation column.
Thermometer / Alcohol Meter Specifications
Features of the wt-1 electronic thermometer:
- measure the temperature of alcohol-containing vapors in the range from 0 to 120 ° C;
- determine the strength (spirituality) of steam in volume percent from 0% to 97%;
- to estimate the alcoholicity of the bottom residue in volume percent from 97% to 0%.
Consider other characteristics of this thermometer:

Switching to the alcohol meter mode
When you press the ON / OFF button, the device turns on. First, the system values are displayed and "60 s" appears. This means that the device will work for 60 seconds, and then turn off. This is done in order to save battery.
If you need to observe the instrument readings for a longer time, then when the mentioned inscription appears on the screen, press ON / OFF again. The appliance will not turn off and the hour will appear on the display. So, the operating mode of the device will last for this time.
Then you need to press the C / F button and hold it until “STEAM” appears on the display: in this mode you can measure the spirituality of the vapors. When you press C / F again, the inscription will change to "SUB": now you can determine the indicator of spirituality in the cube of the device.
In addition, the described model performs the same functions as an electronic thermometer with a probe, that is, it measures the temperature of surrounding objects.
For what purpose is the thermometer used
For bathing infants, the water temperature is not hot, so that the child feels active, comfortable and gradually tempered in it (35-37 ° C). By the way, water should first be boiled if the umbilical cord in the child has not yet healed. In such a situation, the described device will be absolutely indispensable.
To control the degree of frying of meat products, an electronic thermometer with a probe is also useful. For meat, minced meat and fish, it is important to observe the temperature regime of cooking. To do this, the sensor must be immersed in the middle of the thickest part of the product and measure the temperature inside.
We offer temperature values for ready meals:
- Lamb, beef, veal: 52-57 ° C (with blood), 58-62 ° C (average deep-fried with blood), 63-70 ° C (medium deep-fried), 70-75 ° C (full deep-fried).
- Pork: 60-70 ° C (medium heat), 70-75 ° C (full heat).
- Chicken, turkey: 75-82 ° C (baked whole), 68-75 ° C (breast), 75-82 ° C (chicken, wings).
- Duck, goose: 68-75 ° C (baked whole), 60-70 ° C (medium rare breast).
- Stuffing: 67-73 ° C (chicken, turkey), 65-70 ° C (lamb, beef, veal, pork).
- Fish: 60-63 ° C (full roast).
What else is a thermometer useful for
Those who want to cultivate Kombucha need to know that he loves water with a temperature of around 25 ° C and feels bad at 17 ° C.
Many people like to drink tea, adding honey to it, but it is known that at high temperatures, honey loses its healing properties, so the temperature of the tea should be no more than 60 ° C in order to preserve the qualities of honey and consume a hot drink.
And the dough left for fermentation before baking can be considered ready if its temperature has increased from the original by 2 ° C. The initial value of the freshly kneaded dough is about 30 ° C. If the room temperature does not allow the test to achieve the desired indicators, then you need to put the workpiece in a warmer place: the oven, to the battery or in a basin with hot water.
Baking yeast actively multiplies at 25 ° C, and acid-forming bacteria in the dough at 30-40 ° C. By controlling the temperature of the dough, you can avoid getting too acidic or not good-tasting product.
Confectioners actively use such thermometers to determine the temperature of caramel syrup: for hard caramel - from 145 ° C (light - 155 ° C, dark - 170 ° C), soft, for filling - from 118 ° C to 125 ° C.
All these indicators will be controlled by an electronic thermometer with a probe, which is convenient to take with you, easy to use and receive accurate data.
