Bimetal Thermometer

Applications

Bimetal Thermometers are reliable and accurate temperature sensors requiring no electricity or wiring.
Bimetal thermometers are ideal for local, eye-level temperature readings in most process applications.
They can be recalibrated with a turn of the calibration screw on the back of the dial.

Maintenance

1) Cleaning:
a) Keep dial lens clean for proper viewing. Clean using commercial window cleaner.
b) Periodic cleaning of residue from the stem may be required to ensure thermometer sensitivity if installed without a thermowell.
2) Calibration: Periodic calibration should be as determined by the user.
a) Immerse the thermometer stem into a temperature-calibrated medium. Immerse entire stem or 4” (100mm) minimum.
b) Use a small open-end wrench or flat tipped screwdriver to turn the calibration screw. Turn the calibration screw to adjust the thermometer pointer to the correct temperature if necessary.
