High-precision non-contact temperature measurement device

A high-precision non-contact temperature measurement device, comprising:

• a thermal insulation box made of a thermal insulation material and having therein a receiving space;
• a dynamic constant-temperature feedback control module for controlling temperature of the receiving space, the dynamic constant-temperature feedback control module comprising a thermoelectric cooling chip for cooling;
• and
• a non-contact temperature-sensing thermal imager disposed in the receiving space, the thermal insulation box mounted to the non-contact temperature-sensing thermal imager;
• wherein a front cover is disposed on a lateral surface of the thermal insulation box and the lateral surface and the front cover each have a hole and the non-contact temperature-sensing thermal imager observes a target through the holes and thereby the thermal insulation box covers a majority of all sides of the non-contact temperature-sensing thermal imager except for the holes;
• wherein the thermoelectric cooling chip is in contact with the non-contact temperature-sensing thermal imager and absorbs heat and releases the heat away from the non-contact temperature-sensing thermal imager thereby providing a cooling effect for temperature control.
