Information

1. Knowing the temperature range to be measured is an important performance indicator for aluminum pyrometers. Each thermometer has its own specific temperature range. It is recommended that you choose a suitable two-color thermometer according to your measurement requirements. The range must be accurate and comprehensive, neither too narrow nor too broad. If it is too wide, the temperature measurement accuracy will decrease. The price is too high to be expensive, a bit not worth it. The temperature is too low to meet the requirements. According to the law of blackbody radiation, the change in radiant energy due to temperature exceeds the change in radiant energy due to emissivity error in the short wavelength band of the spectrum. Therefore, when measuring temperature, it is recommended to use short wavelengths whenever possible.

2. Understand the measurement accuracy and minimum resolution. The two are two different concepts that are easy to confuse. Measurement accuracy is an indicator to ensure measurement accuracy, and it is also a key indicator to determine the performance of aluminum pyrometers. Resolution is a small measure when measuring a specific temperature.
3. Know the emissivity. According to customer feedback, measurement errors are often encountered with aluminum pyrometers, 50% of which are caused by emissivity. Applicable to various occasions, the surface material and color of the measured object are different (especially the various pipes in the HVAC system), and its ability to emit infrared energy is also different. By adjusting the emissivity, measurement errors caused by the material can be reduced. So it is very important whether the instrument has this function or not.
