Q1. Does the infrared thermal imager emit infrared rays? Is it harmful to the human body?
A1:The infrared thermal imager does not actively send infrared rays or any other light source. These are two different concepts. The temperature distribution is mainly imaged by non-contact absorption/sensing of thermal radiation on the surface of the object by the photosensitive element. If it does not actively send infrared rays, there is no harm.
Q2. Can infrared thermal imagers see through walls?
A2:No, infrared thermal imagers are instruments that sense the surface temperature of objects and visualize them, so they naturally do not have the ability to see through walls.
Q3. Can infrared thermal imagers really see clearly in a completely dark environment?
A3:Infrared detectors sense temperature, and will not be affected by active light sources or not. However, it must be pointed out that infrared presents a temperature distribution map, which is different from the common visible light photography map.
Q4. Does the infrared thermal imager need to touch the object when detecting? Does the distance have any effect?
A4:No, the infrared detector is non-contact, so it does not need to touch the surface of the object to measure the temperature. The detection distance is similar to that of an ordinary camera, which depends on the lens and is within the detection distance range of the lens.
Q5. Is the temperature measurement of infrared thermal imagers accurate?
A5:Since it is non-contact heat, induction temperature measurement imaging, errors are inevitable. Conventional thermal imagers have a temperature measurement range of -20~150℃, with an error of +2℃, human body temperature measurement thermal imagers have a temperature measurement range of 20~45℃, with an error of ±0.5℃, and high temperature thermal imagers have an error control of +2%.
Q6. How many types of thermal imagers are there?
A6:Online (connected to a computer for real-time monitoring), handheld, drone-mounted, robot-mounted, telescope, visible light + infrared dual-light imaging, mobile phone plug-and-play, etc., different pixels have different imaging effects.
