3-Inch Dial Thermometer
This bimetal thermometer measures temperatures from 50 to 550 degrees Fahrenheit and 10 to 290 degrees Celsius. A three-inch glass lens covers the stainless-steel dial for clear reading. The four-inch stem mounts via a 1/2 inch NPT back connection. No NIST-traceable certificate is included.
HVAC and Industrial Technicians
Suits technicians who need a durable, direct-mount thermometer for pipes, tanks or ductwork in the stated range. Not for operators who require a calibrated instrument with a NIST-traceable certificate for quality audits. Not for applications needing a stem length other than four inches.
1/2 Inch NPT Back Connection
The 1/2 inch NPT back connection determines whether the thermometer fits the existing port on your equipment. Verify the thread size and orientation before ordering. The fixed four-inch stem length and back-mount design must match your installation requirements.

Questions about this item
Does the thermometer come with a thermowell or mounting fitting, or do I need to buy a 1/2 in NPT fitting separately?
The stem has a 1/2 in NPT back connection built in, so it threads directly into a matching port; no separate fitting is required unless you want a thermowell for protection.
Should I choose the Fahrenheit or Celsius scale for a range of 50 to 550F?
The dial shows both scales simultaneously — 50 to 550F on the outer ring and 10 to 290C on the inner ring — so a single model covers both.
How accurate is the 50 to 550F reading once the stem is installed in a pipe?
The thermometer is a bimetal dial type supplied without a NIST-traceable certificate, so it provides a direct visual indication but no calibrated accuracy statement for in-situ use.
