Industrial Bimetal Thermometer

This dial thermometer measures temperature from -20 degrees to 120 degrees Fahrenheit and -30 degrees to 50 degrees Celsius. It features a 304 stainless steel housing and stem with a glass lens for durability. The 9 inch stem uses a 1/2 inch NPT connection for secure mounting. A NIST-traceable certificate is included for calibration verification.

Bimetal Dial Operating Limits

The bimetal sensing element responds to temperature changes without external power or signal wiring. Accuracy depends on proper immersion depth in the measured medium. The 304 stainless steel construction resists corrosion in many industrial environments. Glass lens clarity allows direct reading at the point of installation.

Upgrade From Liquid-In-Glass Units

This instrument replaces fragile mercury or alcohol thermometers in pipelines and tanks. The hermetically sealed dial eliminates breakage risk and fluid contamination. The included certificate supports quality systems requiring traceable calibration records. The jump is worth it when safety regulations prohibit glass thermometers or when remote reading is needed.

Questions about this item

Should I pick the Fahrenheit or Celsius scale for my application?

The dial shows both ranges at once: -20 to 120 °F and -30 to 50 °C, so you read whichever unit you need without choosing a version.

What temperature span will this thermometer actually cover on my equipment?

It measures from -20 °F up to 120 °F (-30 °C to 50 °C), suitable for HVAC, refrigeration and general industrial monitoring.

How does the 1/2 in NPT connection limit installation options?

The 1/2 in NPT back mount threads directly into a matching female fitting; you need a compatible port or adapter for any other connection type.
