In certain areas of professional activity such as industry, the medical sector or even scientific research, cutting-edge equipment is essential. Thermometers, these everyday technical assistants, must provide you with the most high accuracy possible, but must also be able to measure temperature over wide measuring ranges . You will find on the market professional thermometer two solutions for taking a high temperature: the thermocouple and the infrared thermometer . Our specialists , experts in high temperature thermometers, will discuss with you how these tools work and guide you in your choice.
Models of professional high temperature thermometers🌡
Industrial ovens, heating systems or production lines are the processes in which high temperature thermometers are most widespread; the temperature range can go from 500°Celsius to 1200°C, even 1500°C for the hottest. Two solutions are available to you for taking the temperature of these high heat sources, namely, the thermocouple and the infrared thermometer .
🔗 The thermocouple
A thermocouple is very quick and easy to use. It is connected to a thermometer to measure the signal and display the temperature. Simply plug the probe into the electronic measuring device and select the temperature setting. The thermocouple measures temperature by generating a potential difference in millivolts across the two terminals of the temperature probe. It is made of an alloy of two precious metals connected by welding at the end. Subjected to a certain temperature, metals generate a voltage in mV which is then analyzed, measured and transmitted by a regulator or any other regulation process, to display the temperature.
Thanks to the thermocouple you can check internal temperature with the probes which transmit the result directly to you on the screen of this digital thermometer.
Typical temperature probes thermocouples are used to measure temperatures up to 1800°C; although it may seem obvious, in the case of use at high temperatures, all the components of the probe must inevitably withstand the temperature in contact with the heat source. #ThanksCaptainObvious 🦸♂️ _
Take the example of this probe professional, it can measure a temperature of 1100°C, however the material with which its handle was made does not resist such a temperature. It will be necessary to ensure that only the metal tube is exposed to the heat source. Other sensors NTC , which means “negative temperature coefficient” and whose maximum Celsius temperature is 200°C, or the probes Pt100 (T°max 700°C), although considered high temperature measurements, have a much lower measurement range.
Then, nothing could be simpler, just connect the thermocouple sensor to any compatible thermometer with it and having a sufficiently high measuring range. You can choose a thermometer without a probe and add the probe adapted to your activity, your use and your temperature measurement. In other words, a professional high temperature thermometer custom made !
🧲 The infrared thermometer
The laser infrared thermometer , which is a digital and contactless thermometer, which certainly allows you to take body temperature (like the forehead thermometers that you will find at the doctor), but it can also be used to high temperatures . Indeed, if you want to check the ambient temperature of an industrial oven which can reach 1800°C, it is possible to do it remotely with an infrared thermometer.
Unlike the thermocouple which measures the temperature nearby , to use the infrared thermometer, nothing could be simpler. Stand a safe and comfortable distance from your target, point the thermometer at the surface to be measured, squeeze the trigger and your laser thermometer Instantly reads temperature.
The real advantage with this type of temperature measurement is that you can do it remotely for any hard-to-reach object. You will also be able to measure most surfaces precisely and quickly.
In addition, the materials of thermometer/sensor not in contact with the heat source, you will simply need to ensure the amplitude of the ideal measuring range for your use.
Choosing your professional high temperature thermometer 💡
The choice of your professional thermometer depends above all on your field of activity and the use you will make of it. Now that you have the features and benefits thermocouple and infrared thermometer , all you have to do is choose the one best suited to your business!
