Now it is in every house, premise, on the street, built-in appliances and does not cause any surprise. But few people know all its varieties and features.
Product Description
Room thermometer is intended for measuring temperature in rooms of any type. It can be used in living rooms, kindergartens and schools, office premises, warehouses and various industries.
Depending on the room in which the temperature is measured, a graduated scale may have different readings:
- From 0 ˚ to +50 ˚.
- From -10 ˚ to +50 ˚.
- From -20 ˚ to +50 ˚.
All of them have a division price of 1˚, and depending on temperature parameters are intended for warm or unheated rooms.
This is the most common device to use. It is a room thermometer that has the largest assortment both in temperature range and in external design.
Variety of appearance
This type of devices perform:
- In a plastic case, this is the most common form. Plastic can be white, black and many other colors. Thanks to which it can be selected in accordance with the interior.
- In a wooden case. It is made of natural wood, painted with varnishes and a measuring scale is built in, applying temperature markings on a wooden base.
- In a cardboard case. To do this, apply pressed dense cardboard with the application of various patterns. This type of thermometer has a souvenir character and has a significant minus in use. This type of thermometer is afraid of high humidity.
- In a metal frame.
- In the glass.
- There are thermometers built into the gypsum enclosure.
Varieties of thermometers
Since the creation of the first thermometer, it has been significantly transformed and modernized. And if the first indoor thermometer was an ordinary device for measuring temperature and consisted of a housing and an alcohol scale, then its followers became more elaborated.
Since then, a more advanced room thermometer has appeared - an electronic version of its predecessor. Battery operated and displays the temperature on a special built-in display. In addition to temperature parameters, an electronic room thermometer can show the relative humidity in the room, and also serve as a clock and even an alarm clock. It all depends on the model.
Another variation is a street-indoor thermometer . It is designed to measure temperature conditions both indoors and outdoors. He, like the previous representative, is electronic, with a built-in display. The screen usually shows the air temperature in the room and on the street, air humidity also indoors and outdoors, and the time of day. Powered by one or more batteries.
That device, which is capable of analyzing and showing relative humidity, has another name - a room thermometer with a hygrometer. It is an alternative to a psychrometric hygrometer, which is used in various industries to determine the temperature and humidity in indoor and storage rooms.
General recommendations for use
After purchasing in the store, it is important to determine the place where to place the room thermometer so that it optimally correctly displays the temperature and humidity in the room.
It is important to keep it away from direct sunlight, heat sources, heating elements and moisture sources.
If it is decided to hang the thermometer on the wall, then it should be interior, the walls in contact with the street can affect the reading of the device.
Electronic appliances can be installed on tables or other furniture, subject to sunlight.
If the thermometer is just installed, then you can evaluate the readings after 20 minutes.
They do not require any additional maintenance, the only condition for electronic representatives is that it is periodically necessary to change the batteries.
