Equipotential temperature measuring device

The invention discloses an equipotential temperature measuring device, which comprises a device main body, wherein a chamber is formed in the device main body; a cover is arranged on the chamber; a temperature measuring module is mounted in the chamber; the temperature measuring module comprises a circuit board and a temperature sensor; a through hole is formed in the cover; the temperature sensor is placed in the through hole; a grounding end cover is arranged on the temperature sensor; and a vertical sheet fixedly connected to the circuit board is arranged on the grounding end cover. According to the invention, as the grounding end cover is in contact with a detected article, the circuit board part and the detected article are effectively connected in an integrated way and a whole body is formed between the circuit board part and the detected article, as a result, interference of high voltage difference does not exist, the damages of electric stress to internal components are reduced and safety and reliabil
