WSSXseriesExplosion proof electric contact bimetallic thermometer is made of aluminum alloy shell, which separates the circuit inside the instrument that may generate sparks and arcs from the explosive gas mixture outside the case through the aluminum alloy shell, thus achieving the purpose of explosion-proof.

A single needle indicating thermometer that uses a bimetallic strip wound into a spiral tube shape with one end fixed and the other free end connected to a pointer, which rotates with temperature changes and drives the pointer to rotate to indicate temperature. It is the presence of carbides and other explosives in the production sites of petroleum, coking, chemical, pharmaceutical and other enterprises during various processes-80～+500℃Temperature measurement of liquid, vapor, gas media, and solid surfaces within the range.
