T-type thermocouple temperature probe. The probe diameter is 0.51mm. It can withstand low temperature-200°C and high temperature within 200°C of measurement.
The wire used is TPT-01-24G-3M-S (T-type thermocouple 24G (wire diameter 0.51mm)-200'C, wire length 3 meters, 3.8mm long 50mm white iron pipe added to the front end.
Can be used with DTM-507, TR-75nw, TR-75A, TR-55i-TC or TR-45.
It measures incredibly low-temperature liquid nitrogen in a liquid nitrogen tank or dry ice.
