Description

Micro Gas Filled series Temperature Switches are devices using the time proven mechanism of Pressure Switches. The precision mechanisms are of stainless steel for arduous atmosphere and high humidity. Several Convenient standard temperature ranges are available. Set point id continuously adjustable over the instrument range. A calibrated scale is provided for approximate switch setting.
