Electronic thermometers operate on the principle of environmental exposure to specific sensors that are controlled by the program. The remote sensor that comes with the kit allows it to be located far from the object of study. Only the probe located at the end of the wire is immersed in the measured medium. This is especially useful when working with extreme pressure, hazardous chemicals (acids, alkalis, etc.), high temperatures, and with any other aggressive media. The presented collection will introduce you to seven electronic thermometers equipped with remote sensors. We paid special attention to the features, and also noted all the existing advantages and disadvantages of each model.

DC-1 - wide temperature range
The model is easy to operate. The thermometer works with a wide range of temperatures, while giving a fairly accurate determination of the level of humidity. The device uses a PC interface. The manufacturer has provided the ability to connect a USB cable. Electronic thermometer gives accurate measurements - 1.3 percent.
Differs in high calibration speed. The device is equipped with a probe-type sensor. Will be suitable for work in the conditions of laboratory researches. Dust and moisture protection complies with IP31 protocol. The thermometer with the sensor and the battery is included in the package, instructions for use are also attached.
Advantages:
- accurate measurements;
- easy to use;
- there is a USB connector;
- acceptable price - 540 p.
Disadvantages:
- not found.
DC-5 - multichannel type sensor
The model is relatively expensive, but the price is justified, since the device has many advantages over cheaper analogues. The device operates in a wide temperature range and has a low error rate. A multichannel sensor is used here. Electronic thermometer has a high calibration speed.
Like the previous model, the DC-5 has a PC series interface. Protection against moisture and dust complies with IP32 protocol. The device is equipped with a function that allows you to measure the level of moisture. Suitable for use in the field and during laboratory studies.
Advantages:
- accurate measurement values;
- ease of use;
- through resistance - up to 6 ohms.
Disadvantages:
- relatively expensive - 2100 p.
Digital 320 - high measurement speed
Electronic thermometer with remote sensor has a high measurement speed, which is equal to 1.2 seconds. The error of this device is no more than 0.8 percent, which gives the right to call it one of the exact among analogues. Here the PC series interface is used.
The manufacturer has placed on the side panel a slot for connecting a USB cable. Suitable for laboratory research, as are most similar models. The thermometer is powered by two batteries, which is enough for three hours. Of the minuses, users mark the launch of the device with some delay.
Advantages:
- high speed and accuracy of measurements;
- the presence of USB-connector.
Disadvantages:
- long calibration;
- low threshold temperature;
- starts up with a slight delay;
- relatively expensive - 1600 p.
RST 77110 - temperature mode control in three modes simultaneously
The model operates in a wide range of temperatures: from -50 to 200 degrees. Of the additional functions here it is possible to note the ability to save temperature values in the device’s memory. The remote sensor is wireless, its reception radius is about 40 meters.
Complete with a thermometer comes only one, but you can connect up to three pieces. The device collects and transfers data every seven seconds. It is powered by batteries that are included in the package. The informative display is backlit. The thermometer measures the temperature of air, liquids, mixtures and soil.
Advantages:
- there is a wall mount for more convenient work with the device;
- light indication is provided;
- remote sensor with a metal probe;
- signal for exceeding the minimum / maximum values.
Disadvantages:
- relatively expensive - 2300 p.
Ea2 EN209 - Weather Station
The model works in the range from -40 to 50 degrees. It is also possible to determine the level of humidity on the street and in the room in the range from 20 to 99 percent. Of the additional functions of the device is to provide receiving a weather forecast, the presence of an alarm clock, clock, calendar.
The latest values are stored in the device’s memory. Wireless remote sensor operates within a radius of 30 meters. You can connect up to three sensors, but only one is included in the package. Food is carried out both from a network, and from batteries.
Advantages:
- there is an indication of the level of charge;
- information is displayed with special characters and numbers;
- there is a choice of units of measurement;
- The display is backlit.
Disadvantages:
- relatively expensive - 5 thousand rubles.
Ea2 AL803 - the ability to measure external and internal temperature
The model has the ability to measure the temperature both outdoors and indoors. The device operates in the range from 0 to 50 degrees (internal) and from -40 to 50 (external). It also determines the level of humidity (range from 20 to 99 percent). The device is powered by AAA batteries. An informative monochrome display displays an animated weather forecast. There is an alarm function, a clock and calendar display.
Advantages:
- small dimensions - 80 x 158 x 19 mm;
- high measurement accuracy;
- charge level indication.
Disadvantages:
- works only from batteries;
- relatively expensive - 2500 p.
Oregon Scientific WMR89 - barometer availability
The model differs in that it has a built-in barometer. It displays atmospheric pressure on the display. An electronic thermometer with a remote sensor measures temperature and humidity, and also determines the direction, wind speed and level of precipitation.
Of the additional features worth noting displayed on the screen weather forecast, lunar and normal calendar, clock. For convenience, the device stores the latest measurement values in the device’s memory. Power is supplied from the network and from the batteries. Information is displayed in the form of special characters and numbers.
Advantages:
- wireless remote sensor operates within a radius of 100 meters;
- the package includes three sensors;
- there is a USB.
Disadvantages:
- expensive - 10 thousand rubles.
