Radiation thermometer measures temperature by detecting thermal radiation (infrared rays) from an object.
Compared to thermometers that use thermal conduction, such as thermocouples, it is possible to measure temperature non-contact and high-speed.
What is radiation thermometer?
If you're unsure how to choose! How to choose radiation thermometer
Selecting radiation thermometer can be difficult, but here are some important points to keep in mind.
1. Usage: Fixed, portable
When installing and measuring on-site, the installation type is usually selected.
If you need to measure objects on the spot or for maintenance purposes, choose a portable model.
2. Measurement range
The temperature measurement range of radiation thermometer must be selected according to the purpose of use.
In particular, make sure that the temperature you are measuring falls within this range.
3. Precision
The accuracy of the thermometer has a significant impact on the measurement results.
Choosing a high accuracy model will enable more reliable measurements.
4. Emissivity setting function
The intensity of the energy radiated from the surface of an object depends on emissivity of the object.
By choosing a thermometer that has the ability to set emissivity, you can measure temperature accurately.
5. Target size and measurement distance
radiation thermometer must be selected according to the size and distance of the object to be measured.
When target sizes are small, it is important to measure at the correct distance.
It is important to pay attention to field of lack of view and area effect, and ensure that the object to be measured fits within field of view of the thermometer.
6. Wavelength characteristic
Each radiation thermometer receives different wavelengths of infrared radiation.
It is important to select a thermometer with the optimal wavelength depending on the material and temperature of the object to be measured.
7. Design and UsabilityThe design of the thermometer and its display functions (back-lit illumination display etc.) are also important points to consider when selecting a thermometer.
operation and visibility are particularly important when considering use in the field.
