The reason why the thermal imaging temperature measurement gate machine can perform temperature screening is that it can convert temperature into visual images. The pixels in each thermal image are temperature points, and the number of temperature points is related to the infrared pixels of the device itself. The infrared pixels are 384 * 288, which means there are 110000 temperature points in one thermal image, equivalent to using 110000 temperature guns to measure temperature at the same time. The efficiency will be significantly improved.
The fixed infrared thermal imaging temperature detection system is usually deployed at the entrance and exit of transportation stations, with high detection accuracy (up to ± 0.2 ℃), wide field of view, long detection distance, and can support about 10 meters. At the same time, it can detect about 10 targets. In order to ensure detection accuracy, fixed infrared thermal imaging temperature detection systems are usually equipped with a constant temperature "blackbody" that is consistent with the normal human body's thermal radiation energy as a reference standard for real-time calibration. At present, the price of fixed infrared thermal imaging temperature monitoring equipment is relatively high.
Handheld infrared thermal imaging temperature measurement devices can perform one-on-one or one to many detection, but the detection accuracy (some errors are greater than ± 0.5 ℃), field of view, and detection distance (some are only 0.5m) are mostly lower than fixed and mobile infrared temperature measurement devices. In terms of price, the accuracy varies, so the price also varies.
Infrared thermal imaging temperature measurement gatekeeper, similar to a fixed infrared thermal imaging temperature detection system, but with lower detection accuracy and detection distance. Its testing distance is 0.3-3 meters and the accuracy is ± 0.5 ℃.
