Value Brand Bimetal Thermometer 50-550°F 10-290°C 2in Dial 9in Stem

Purpose and Fit

This analog bimetal thermometer measures temperatures from 50 to 550 degrees Fahrenheit (10 to 290 degrees Celsius) with a two-inch dial and a nine-inch stem. It suits technicians who need direct-reading temperature data in industrial, HVAC or mechanical settings where electronic sensors are impractical. Buyers who require digital logging, alarm outputs or remote monitoring should choose a different instrument.

Sustained Operation

The hermetically sealed stainless steel case protects the bimetal coil from moisture and contaminants during continuous exposure to process heat. Accuracy remains within plus or minus one percent of full scale across the entire range, so readings stay consistent during long duty cycles. The glass window and external adjustment let operators verify calibration without breaking the seal.

Installation Notes

The quarter-inch NPT back connection threads directly into standard pipe fittings; the quarter-inch stem diameter fits common thermowells. Over-tightening the fitting can distort the case and shift calibration, so apply only moderate torque. Ensure the stem is immersed sufficiently in the media to avoid stem-conduction errors, and keep the dial face visible for routine checks.
