Model ZDG-150 Thermopile Gauge Tube
Model ZDG-150 Thermopile Gauge Tube
Thermopile gauge tube is a type of thermocouple gauge tube with the special construction and the temperature compensation system,which is hid of impact caused by ambient temperature on the vacuum readings of the common thermocouple gauge tube and can giue reliable and accurate vacuum pressure readings without being affect by the ambient temperature.
Thermopile gauge tube has been commonly used for measure high & low vacuum.It is maily intended for the fabrication segment of cryogenic storage tanks & tankers,refrigerators and air conditions.
