Dwyer® Bimetal Thermometer, BTB3405D, 0-250°F (-20-120°C), 3" Dial, 4" Stem, Back Connection

BT Series Bimetal Thermometers offer accurate, reliable service even in the most difficult environments. These corrosion-resistant units are constructed of stainless steel and are hermetically sealed to prevent glass fogging. The bimetal element directly drives the pointer, eliminating gears and linkage. An external reset screw allows for field calibration and the easy-to-read aluminum dial minimizes parallax error. Choose rear connection, bottom connection or adjustable angle for easy viewing and installation. Adjustable models can be rotated 360° and tilted over a 180° arc. NOTE: When used in pressurized applications, use a suitable thermowell.
