These dampened-movement bimetal thermometers operate in measurement ranges from -100°F to 1,000°F (-70°C to 540°C) and are available in adjustable-angle, center-back, and lower-back mount process connections. They are factory calibrated and feature external reset for field calibration. The thermometers are said to be accurate to ±1% of full scale in accordance with ASME B40.200 and are actuated by a sensitive bimetal helix coil. Silicone-free gel in the thermometer stem dampens vibration effects. To prevent fogging and moisture damage to working components, the dials are hermetically sealed.
