Dial thermometer with NIST-traceable certificate

This 3 inch dial thermometer measures from -20 degrees F to 120 degrees F and includes a NIST-traceable calibration certificate. The 304 stainless steel housing and glass lens resist corrosion in harsh environments. It connects via a 1/2 inch NPT bottom mount for direct immersion in liquids or gases.

Bimetal sensing for steady readings under

The bimetal element responds to sustained temperature changes without the drift common in electronic sensors during long runs. No power supply or signal conditioning is required, so the instrument remains accurate during extended process monitoring. The glass lens maintains clarity where plastic would cloud from chemical splash or UV exposure.

Check stem length and mounting before ordering

The 4 inch stem must reach the measurement zone without touching vessel walls that could conduct heat away. Verify the 1/2 inch NPT thread matches your existing port or fitting. Ensure the -20 to 120 degree F range covers the full operating envelope of your application.

Questions about this item

Does the 304 stainless-steel housing affect heat conduction during long monitoring sessions?

The 304 stainless-steel housing conducts heat evenly, so the dial reflects true ambient temperature even after hours of continuous use.

What pipe fitting is required to install the 1/2 in NPT stem?

A matching 1/2 in NPT threaded port or bushing is needed to secure the 4 in stem in the process line.

Can the -20 to 120 F scale be read accurately on older gauges calibrated in Celsius only?

The dual-scale face shows both -20 to 120 F and -30 to 50 C, letting you cross-reference legacy Celsius instruments directly.
