When the infrared pyrometer is measuring, it will inevitably be affected by some factors. What are the main factors?

Ambient temperature factor

The instrument should be used in strict accordance with the ambient temperature indicated by the instrument's technical indicators. If the instrument exceeds this range, the measurement error of the instrument will increase or even be damaged. When the ambient temperature is high, air-cooling, water-cooling devices or thermal protective sleeves can be used.
air quality factor

Smoke, dust and other pollutants in the air and unclean lenses will make the instrument unable to receive enough infrared energy to meet the measurement accuracy, and the measurement error of the instrument will increase. Therefore, it is best to keep the lens clean frequently, and an air blower can help keep the lens free of contamination.

Electromagnetic Interference Factors

The instrument should be kept as far away as possible from potential sources of electrical interference, such as electrical equipment with large load changes. Use shielded wire for the output and input connections of the in-line instrument and ensure that the shielded wire is well grounded. In strong interference environments, use external protective conduits, rigid conduits are better than flexible conduits. Do not introduce AC power from other equipment into the same conduit.
envirnmental factor

When there are other objects with higher temperature, light sources or radiation from the sun around the measured target, these radiations will directly or indirectly enter the measurement optical path, resulting in measurement errors. In order to overcome the influence of environmental radiation, first of all, it is necessary to prevent the environmental radiation from directly entering the optical path. The measured target should be filled with the instrument's field of view as much as possible. The indirect interference of environmental radiation can be eliminated by blocking.
