Bimetal Dial Thermometer 0-250°F

The ZORO SELECT bimetal thermometer measures temperature from 0 to 250 degrees Fahrenheit or -20 to 120 degrees Celsius. A 3 inch dial provides clear local readings. The 1/2 inch NPT back connection threads directly into process piping or equipment. Stainless steel housing and a glass lens suit industrial environments.

NIST-Traceable Calibration Certificate Included

Each unit ships with a NIST-traceable calibration certificate. This documents accuracy against national standards at the time of manufacture. Users can install the instrument immediately without sending it to a third-party lab. The certificate supports quality audits and regulatory compliance records.

9 Inch Stem Length Determines Fit

The fixed 9 inch stem sets the insertion depth into the process stream. Installations requiring a shorter or longer reach cannot use this model. Verify the required immersion length against the vessel or pipe specification before ordering. No stem length alternatives are offered for this part number.

Questions about this item

Does the bimetal element in this 3 in dial thermometer require periodic recalibration?

The bimetal thermometer is a mechanical instrument with no user-replaceable parts or scheduled recalibration interval.

What temperature limit stops the 0 to 250F dial thermometer from reading higher under continuous use?

The dial scale ends at 250 degrees F, so sustained exposure above that point exceeds the calibrated range.

How much heat does the stainless steel housing and glass lens add to the process when the thermometer runs all day?

The thermometer is a passive sensor with no power draw, so it adds no heat to the process during continuous operation.
