WSS Series bimetallic thermometers

Product specification: WSS
 Summary
 Bimetallic indication thermal resistance (thermocouple) is an integration  temperature measurement instrument with on site indication and remote  transmission display function.It can be used directly to measure the  temperature of gasses、liquids and
 substances. The indication value can be read distinctly on site.And the  signals can be transmitted to the control room.The
 transmitted signals include Pt 100,K type and E type thermal resistance  signals,also the (4~20)mA standard signal after transmission. It plays a role  as an instrument with two functions.
