Many people are interested in this indicator several times a day, while the goal may be both a domestic desire to understand how warm to dress today, and a production need. That’s what an electronic thermometer with a remote sensor is for.

An electronic thermometer with a remote sensor is necessary to measure the temperature outside the window

Scope of use of electronic thermometers for measuring air temperature

This digital device is distinguished by practicality and ease of use. Its main purpose is to measure the temperature regime both indoors and outside.

In comparison with mercury electronic thermometers differ in higher accuracy of indicators

First of all, electronic thermometers are relevant in everyday life: they allow you to easily and quickly find out the temperature outside. In addition, modern window thermometers for plastic windows perfectly fit into the design of today’s apartments, unlike the old pre-revolutionary thermometers.

In addition to home use, such thermometers are used:

in technological premises;
in aquariums;
in tanks where animals are kept;
in warehouses;
for baths and saunas.

One of the important qualities of electronic thermometers with a remote sensor for home and industrial needs is the ability to continuously monitor the temperature regime both indoors and outside, which is especially important for the safety of products, maintaining the vital activity of some animals and creating a comfortable microclimate.

Some models of electronic thermometers are mounted on the window glass

Useful advice! If you need to measure the temperature not outside the window or within the room, but a specific object, pay attention to infrared electronic thermometers: they determine the temperature by simply pointing at the object you are interested in.

Electronic thermometer with remote sensor: device and principle of operation

In order for the use of this device to be convenient and bring maximum benefit, it is worth understanding the principles of its functioning.

How to use electronic thermometers with a remote sensor

The device comes with two parts:

The main block. It is equipped with a display and is located in the room.

Remote sensor. For effective operation, it should be located at a distance of no more than 65 m from the main unit.

An electronic thermometer is a fairly simple device that is not demanding to the operating conditions

The sensitive thermocouple is enclosed in a rubber, plastic or metal shell. From it, temperature pulses are transmitted to the main unit. In wired models, the length of the wire is 1-3 m, but recently wireless options have become increasingly popular, where a radio transmitter with a thermocouple is located on the street.

A miniature sensor is pushed into the street by drilling a small hole in a wooden window frame, or through a rubber exhaust in the case of plastic shutters. Often, the sensor is carried out through the rubber seal of the plastic sash and fixed to the window glass with a suction cup. At the same time, the main sensor can be easily and conveniently placed in a room on a windowsill, table, shelf or even hung on the wall.

The principle of placing the thermometer on the refrigerator is similar. The device body is attached to the refrigerator with a suction cup or next to the refrigerator, while the sensor is placed inside the camera.

Electronic thermometers are also used to measure the temperature inside the refrigerator

Features of operation of electronic thermometers with a remote sensor

Due to the high sensitivity of window street thermometers for plastic windows, the measurement error is minimal. You can see the measurement data on the display of the main unit. Thus, the additional convenience of an outdoor digital thermometer is in the absence of the need to peer into the mercury thermometer, trying to distinguish the readings by a barely noticeable column. On an outdoor window thermometer with a remote sensor, all information is clearly and clearly displayed on a contrasting display in your room.

Useful advice! When buying an outdoor electronic thermometer with a remote sensor, pay attention to models equipped with a humidity sensor. This way you will be able to track changes in this indicator and will be warned about the probability of precipitation.

Electronic thermometers: reviews of work

Before buying an electronic device, it is important to weigh the pros and cons. And here you should pay attention to the experience of real people using the device for a long time.

Often electronic thermometers with a remote sensor are used to measure the temperature of water in an aquarium

According to user reviews, there are two main aspects that are advised to consider when buying:

Make sure that the thermometer you are purchasing is moisture resistant. Unfortunately, not all models have this characteristic, which is of fundamental importance if you are going to use an electronic thermometer to measure the temperature outside.

When buying, ask for how long the battery lasts. Learn how to take out and put the batteries back in so that you can easily replace them if necessary. It is evidenced by the fading of the display numbers. If there are two batteries, check which one of them is hooked, and replace it – it often happens that only one of the batteries requires replacement, which saves money.

Some models of thermometers are quite compact and allow you to carry the device with you

From the useful functions , according to their own experience , users distinguish:

built-in hygrometer for measuring humidity outside the window, because without this indicator it is difficult to maintain a comfortable indoor climate; however, most thermometers measure humidity only indoors, so a thermometer with a remote sensor is relevant to you;
a household home thermometer with a hygrometer allows you to navigate much more accurately in weather conditions and will become a real home weather station, because the indicators in your area may differ markedly from the one where meteorologists take measurements;
the presence of a hygrometer allows you to track climate change on the street during the day and, for example, choose the right moment to ventilate the room;
by comparing humidity indicators, you will be able to determine the source of dampness in the room.

Thus, modern thermometers with a remote sensor are not limited to simply measuring the temperature outside or indoors and allow you to analyze weather indicators in any conditions.
