PCR instrument temperature calibration device with double measurement channels

The utility model relates to the technical field of medical instrument temperature detection, in particular to a PCR instrument temperature calibration device with double measurement channels, which can simultaneously calibrate the temperature of a temperature control module Block and a hot cover of a PCR instrument through the double measurement channels including an upper temperature sensing part and a lower temperature sensing part at a measurement end. The defects that in the prior art, a temperature calibration device can only calibrate the temperature accuracy of a temperature control module Block, and cannot evaluate the temperature of an upper heating cover of the PCR instrument at the same time, or only the center temperature of the upper heating cover is calibrated, and the temperature uniformity of the upper heating cover of the PCR instrument cannot be evaluated are thoroughly overcome, the accuracy and comprehensiveness of temperature calibration of the PCR instrument are ensured, and the accurac
