Series 8481 - Resistance Thermometer with Digital Display
Threaded、Intelligent
 
 
Description
Series 8421 resistance thermometer with digital display can be combined with a variety of thermowells. Use without thermowell is recommended only for specific applications.

This series of resistance thermometers with digital display can replace measuring elements.The process connection, connection method and sensor insertion length can be used with thermowells, which are suitable for the size and application of various thermowell.

This series of resistance thermometer with digital is equipped with LCD display.
