What was a temperature meter?
With a DBV-T antenna, TV signals can be received and then transmitted to the set-top box or the DVB-T tuner built into the TV.
What temperature measuring devices are available?

Temperature measuring device
Temperature measuring devices come in many different forms in private and commercial buildings. They are used, for example, as temperature meters in individual rooms to regulate the heating, or as handy temperature meters in the room or garden to provide information about the current temperature. They are often used by professional users, such as craftsmen, to check temperatures at various points. With clamp-on ammeters, insertion probes, touch displays and many other extras, they can support in many areas.
Frying Oil Tester
A frying oil tester is a common temperature gauge used to check the heat of frying oil or frying fat. Since very high temperatures are used for frying, these aids are mainly used in professional kitchens at home. They are subject to the HACCP standard, which ensures the food safety of kitchen appliances and utensils.
Temperature immersion sensor
immersion sensors are used to measure temperatures in gaseous media and are therefore usually permanently mounted. They are used, for example, for monitoring heating systems and similar building technology. For the evaluation of the data, the combined use with smartphones or tablets is also possible.
Surface thermometers
Surface thermometers are primarily contact thermometers. They measure the temperature on surfaces with a sensor that is optimally shaped for this purpose. Because they are often used in kitchens, many of these devices follow HACCP standards for food safety and can be cleaned at any time. Additional functions, such as minimum and maximum, are also possible.
Temperature transmitters
as part of the control center are used temperature transmitters in various areas to measure temperatures during the current process and in the case of a signal to the control technology or to trigger an alarm. In private households, they are usually found in heating systems. These thermometers work with calibrated values and meet different standards (depending on model).
What do you need to pay attention to when purchasing temperature measuring devices?

- Displays the minimum or maximum of a measurement
- Resolution: Specifies the rounding of the measurement result, e.g. 0.5° C
- Data logger function and software
- Power supply: Number and type of batteries
Practical advice
Numerous accessories are available for temperature measuring devices and especially handheld measuring devices. A lot is possible from the practical carrying case via protective covers. Additional cables, mounting aids and more may also be required for temperature meters that are permanently installed.
Different sensor types for temperature measuring devices
The temperature sensors of temperature measuring devices can be manufactured from many different metals and precious metals. The sensors are made up of several alloys or pure metals and transmit the signals of the measurement to the measuring device.
- E: NiCr-CuNi
- J: FE-CuNi
- K: NiCr-Ni
- N: NiCrSi-NiSi
- R: PtRh Pt
- S: PtRh-Pt
The Pt1000 probe is often used for special temperature sensors, such as temperature transmitters. Many more variants are possible.
Save energy with clever temperature measuring devices
With the constant networking and central control of many areas in houses, heating technology is becoming increasingly intelligent. Temperature measuring instruments are indispensable tools for successful energy saving concepts in households. They continuously check the current temperature and initiate the switching on or off of different systems.
In centrally controlled heating systems, this concept is realized by means of thermostats, but even exact and independant temperature meters can provide a good overview of the room climate on suitable wall surfaces.
FAQs: The most common questions about temperature measuring devices
Which temperature meter is suitable for the kitchen?
Wherever there is contact with food, only devices that are considered to be food safe should be used. For professional kitchens, it is therefore advisable to choose a device that has been designed according to HACCP and meets all hygiene guidelines.
Which temperature measuring devices have a calibration certificate?
For numerous systems and also for commercial users, temperature measuring devices are necessary, which fulfill the necessary standards. If a model has a calibration certificate, the manufacturers not only point it out, but also inform about the standard to which it is subject. Common standards are DAkkS and ISO.
Can measured values be saved and read out?
Many manufacturers offer numerous additional functions for temperature measuring devices, especially for commercial applications. This also includes a supporting software and data logger function, which keeps the measured values ready for evaluation.

Conclusion: How to buy the right temperature meter
Many temperature meters are specifically designed for a particular application area. These include, for example, temperature transmitters, as well as surface thermometers or temperature immersion sensors. With their specially manufactured and optimally adjusted temperature sensors, they are not suitable for measuring room temperatures or for use in the food sector. Before purchasing, you should therefore determine what a temperature measuring device is needed for and then select the corresponding model.
If you want to dedicate yourself with a hand-held measuring device to many different measuring points, you should pay attention to the corresponding certification and an adequate measuring range. Even technical extras such as data loggers, special display values and calibratable values are important details for many applications.
