Henan Infrared Forehead Temperature Gun Factory: Factors Affecting the Measurement Accuracy of Infrared Thermometer

　　Henan infrared forehead temperature gun factoryXiaobian tell you, infrared thermometer measurement, will inevitably be affected by some factors, then what is the main factor,Henan infrared forehead temperature gun factoryThe small series will introduce you to the main factors:

① Environmental factors

The infrared thermometer should be used in strict accordance with the ambient temperature indicated by the instrument's technical indicators. If it exceeds this range, the measurement error of the instrument will increase or even be damaged. When the ambient temperature is high, air-cooled, water-cooled equipment or heat protection can be used. Cover, the thermal protection cover can be used normally below 200.

When the handheld thermometer is used from one environment to another, the accuracy of the instrument will be temporarily reduced. In order to obtain the ideal temperature measurement result, the instrument should be placed on the work site for a period of time (at least 30 minutes is recommended) to balance the instrument temperature and ambient Temperature, air quality factors.

Smoke, dust, other pollutants in the air, and unclean mirrors will make the instrument unable to obtain enough infrared energy to meet the measurement accuracy and increase the measurement error of the instrument. Therefore, the lens must be kept clean frequently, and the air filter helps Prevent lens pollution.

② Electromagnetic interference factors

The instrument should be far away from potential electrical interference sources as much as possible, such as electrical equipment with large load changes. The shielded wire is used to connect the output and input of the online instrument, and to ensure that the shielded wire is well grounded. In strong interference environment, rigid conduit has better external protection than flexible conduit. The same conduit shall not be introduced into the AC power supply of other equipment.

③ Environmental factors

When there are other high-temperature objects, light sources or solar radiation around the measurement target, these radiation will directly or indirectly enter the measurement optical path, causing measurement errors. In order to overcome the influence of environmental radiation, we must first avoid environmental radiation from directly entering the optical path, and try to make the measurement target Filled with the field of view of the instrument, thereby indirectly interfering with environmental radiation, which can be eliminated by blocking.

④ Measurement angle coefficient

In order to ensure the accuracy of the measurement, the instrument should measure along the direction of the surface of the measured object (perpendicular to the surface of the measured object). If the normal direction cannot be guaranteed, it should also be measured within 45 angles of the normal direction, otherwise the instrument display value is low.
