What to do if er1 appears on the infrared thermometer
1. The output error of the infrared thermometer is large: If the online infrared thermometer in the online infrared thermometer is replaced, the linear change range of the new infrared thermometer may not be consistent with the original one, resulting in sensitivity errors. Usually, after changing the infrared thermometer, it needs to be recalibrated. Of course, the online infrared thermometer has a large output error, and it is also possible that the infrared thermometer was not calibrated properly when leaving the factory. At this point, recalibration is sufficient.
2. The output signal of the infrared thermometer is unstable: This reason is due to the temperature source itself. Many temperature sources themselves are generally not constant temperatures. If possible, it can be observed under important indoor temperature conditions and other instruments and meters can be used to monitor whether the output signal of the infrared thermometer is stable. If only the instrument display is unstable, it is that the anti-interference ability of the display instrument is not strong.
What is the market prospect of infrared thermometers?
The market prospects for infrared thermometers are promising, especially during the protest period when infrared thermometers became an important tool for measuring body temperature. Infrared thermometer is a specialized tool suitable for quickly identifying workers whose body temperature exceeds a specific temperature in a group, such as at ticket gates, universities, etc. It fully plays a key role.
Advantages of infrared thermometer:
1. Non contact measurement: It does not need to touch the surface of the measured temperature field, so it is not easy to affect the situation of the measured temperature field. The infrared thermometer itself is not damaged by thermal stress.
2. Accurate measurement coverage is wide: due to its right and wrong touch temperature measurement, the infrared thermometer does not need to be under high or low thermal stress, but only operates at all normal temperatures or within the allowable standards of the infrared thermometer. Under normal circumstances, the detectable range can range from negative tens of degrees to over 3000 degrees.
3. Faster temperature measurement speed: i.e. fast response speed. If the infrared radiation of the overall target is received, it can maintain a constant temperature in the short term.
4. High accuracy: Infrared thermometers are not easy to damage the temperature distribution of the object block like capacitive grid temperature measurement, so precise measurement is more accurate.
5. High sensitivity: If there is a slight change in the temperature of the block, the kinetic energy of the radiation source will undergo significant changes, making it easy to measure. Temperature detection for subtle temperature transitions can be carried out.
6. It can measure the temperature throughout, and detect the temperature of fitness or rotating objects. Application security and long lifespan.
