More and more people, when choosing thermometers for household needs, choose an electronic thermometer with a probe. This device greatly simplifies and speeds up the process of measuring temperature in a variety of situations.
Distinguishing feature of probe thermometers
The main feature of these devices is the presence of a probe, which is a kind of thin knitting needle. With its help, when immersed in the area under study, the temperature of the area with which it comes into contact is determined.
Inside the probe is a thermocouple that quickly reacts to the environment and transmits data to the body of the device, where they are converted into digital values and displayed.
Varieties of probe
The probe itself can be foldable, curved or variable thickness (thin at the end and with a large diameter at the base).
Its connection to the body can be either direct or with a flexible wire. In some models, communication takes place using a radio signal, in which case the probe is separated from the thermometer body.
Electronic thermometerwith a probe, the photo of which is presented in the article, is a model in which the body is directly connected to the probe rod.
Benefits
Let's talk about what attracts the described devices:
1. Wide temperature range supported by an electronic thermometer 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 counterparts. 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 object or environment under study and determine the temperature of the area with which the sensor is in contact. It can also be simply leaned against the object under study to determine, for example, the surface temperature.
3. The digital thermometer with a probe is durable, lightweight and compact. It is convenient to carry in your pocket or keep in the car's glove compartment so that it is always at hand.
4. It works quickly: just immerse the sensor in the test environment for 5-7 seconds and the display will show the temperature in Celsius or Fahrenheit.
5. By the way, the indicators are updated every second. If desired, 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 you to determine the degree of heating or cooling of the substances under study with maximum reliability.
7. The thermometer is easy to use and care for. Basic control is carried out using a couple of buttons, and to clean the probe from dirt, just wipe it with a damp cloth and wipe it dry with a napkin.
8. It has a simple battery - a battery (one or two) type AG13: A76, LR44, SR44W, GP76A. Her work lasts approximately 2,000-3,000 hours.
Scope of application
The benefits that an electronic thermometer with a probe brings can hardly be overestimated. It is sure to come in handy if you like to cook deliciously, grow crops or indoor plants, service a car or other equipment, do construction and repair, or run a household.
In addition to these functions, some electronic thermometers have the ability to determine the alcohol content (strength of drinks), which is useful in brewing and preparing alcohol.
To choose the best thermometer for specific purposes, you need to consider the features of different models.
Electronic thermometer TR-101
It is also called an electronic kitchen thermometer with a probe, as this model is often used in cooking. The sensor detects the temperature in liquids, bulk and semi-solids. With it, it is convenient to assess the readiness of food. 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 a dish or baby food is, understand whether the bird is ready in the oven, remove the barbecue from the fire in time, and alsomake sure the baked goods inside are not soggy. For this, the described device is needed.
Suitable electronic thermometer with a probe for water: determines its temperature in a pot, bath, aquarium or pool.
Controlled by buttons:
- ON/OFF – turn the device on or off.
- HOLD - fix the indicators. By clicking on it, you save the last temperature readings and you can view it closer if it is inconvenient to do this during measurements. To continue measurements, press HOLD again.
These are the two main buttons that almost all models of such thermometers are equipped with. But there may be other controls 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 temperatures recorded by the device, however, these indicators can be reset only by removing the battery from the thermometer, restarting it in this way.
Disadvantages - the inability to determine the temperature inside the oven during cooking, as the body of the thermometer can melt from high temperatures.
Thermometer with probe on wire
Electronic thermometer with remote probe, needed for more comfortable temperature measurement in various conditions:
- Due to the movable sensor attached to the body with a flexible wire, it can be placed inside the oven to determine the temperature of the oven itself.oven or stick directly into the baked product.
- With it it is much more convenient to view 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 a suspended state.
- Many models to help housewives are equipped with a timer, a countdown system. You can set a certain temperature on the display using the program and stick the probe into the prepared product. When the dish reaches the desired temperature, the electronic thermometer will notify you by beeping.
Thermometer and alcoholometer: two in one
The electronic thermometer with wt-1 probe is also named in the instructions as "ETS 223 electronic thermometer/spiritometer". For the exact designation and identification of this model, there is an inscription wt-1. on the case above the display
Let's immediately clarify that it is impossible to measure the strength of a liquid with such a device, because it determines the actual alcohol content at an ambient temperature of at least 78 ° C. That is, it is suitable for these purposes only when directly connected to the moonshine still.
Indicators are displayed on the display in real time. For practical use, two ETS 223 alcohol meters are used: one is connected to a distiller, the second to a distillation column.
Temperature/alcohol meter specifications
Possibilities of electronic thermometerwt-1:
- measure the temperature of alcohol-containing vapors in the range from 0 to 120°C;
- determine the strength (alcohol content) of steam in volume percent from 0% to 97%;
- estimate the alcohol content of the VAT residue in volume percentage from 97% to 0%.
Consider other characteristics of the named thermometer:

Switch to alcoholmeter mode
When you press the ON/OFF button, the device will turn on. The display first shows the system values and "60 s" appears. This means that the device will work for 60 seconds, after which it will turn off. This was done in order to save battery.
If you need to observe the readings of the device for a longer time, then when the above inscription appears on the screen, you should press againON/OFF. The appliance will not turn off and the display will show "hour". This means that the operating mode of the device will last for this time.
Then press and hold the C/F button until "STEAM" appears on the display: in this mode you can measure the alcohol content of vapors. When you press C/F again, the inscription will change to "SUB": now you can determine the alcohol content in the machine's cube.
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 a thermometer used
For bathing babies, the temperature of the water is not hot, so that the child feels active, comfortable and gradually tempered in it (35-37°C). By the way, the water should be boiled first if the child's umbilical cord has not yet healed. In such a situation, the described device will be absolutely indispensable.
To control the degree of roasting 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 temperatures for ready meals:
- Lamb, beef, veal: 52-57°C (rare), 58-62°C (medium rare), 63-70°C (medium), 70-75°C (full done).
- Pork: 60-70°C (medium), 70-75°C (full).
- Chicken, turkey: 75-82°C (whole roast), 68-75°C (breast), 75-82°C (leg,wings).
- Duck, goose: 68-75°C (whole roast), 60-70°C (medium breast).
- Minced meat: 67-73°C (chicken, turkey), 65-70°C (lamb, beef, veal, pork).
- Fish: 60-63°C (done).
What else is a thermometer useful for
Those who want to grow kombucha need to know that it likes water around 25°C and doesn't do well at 17°C.
Many people like to drink tea with honey, but it is known that honey loses its healing properties at high temperatures, so the temperature of tea should not exceed 60°C to preserve the qualities of honey and drink a hot drink.
And the dough left for fermentation before baking can be considered ready if its temperature has risen from the initial one by 2°C. The initial value of a freshly kneaded dough is about 30°C. If room temperature does not allow the test to reach the desired values, then you need to put the workpiece in a warmer place: the oven, to the battery or in a basin of hot water.
At 25°C, baker's yeast actively multiply, and at 30-40°C, acid-forming bacteria in the dough. By controlling the temperature of the dough, you can avoid getting an overly sour or unfermented 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 stuffing - from 118°C to 125 °C.
Control all these indicators will allow an electronic thermometer with a probe, which is convenient to take with you, easy to use and get accurate data.
