Series BTO Bi-Metal Thermometer

Brand: Dwyer Instruments, LLC

The Series BTO Bimetal Thermometer with Transmitter Output eliminates the need for a separate thermometer and transmitter.

By only needing one connection, the BTO series reduces installation cost and saves space. The head-mount transmitter is located in a weatherproof thermal head located on the side of the stem. 

The BTO series is ideal for use on power generating boilers, skid mounted compressors, and thermal oxidation systems.
