Compact Industrial Thermometer

The Value Brand Compact Thermometer measures temperatures from 20 to 180 degrees Fahrenheit with a bottom-mounted connection. It suits industrial maintenance crews and facility engineers who need a durable, liquid-in-glass instrument for pipe or vessel monitoring. The brass thermowell and straight shank provide secure installation in standard half-inch NPT fittings.

Measurement Range and Graduations

The scale covers 20 to 180 degrees Fahrenheit and zero to 80 degrees Celsius with two-degree Fahrenheit and one-degree Celsius graduations. Liquid-in-glass operation requires no power source but limits readability in low-light conditions. Response time depends on process fluid velocity and thermowell immersion depth.

Bottom Connection Orientation

The bottom-mounted stem directs the dial downward for vertical pipe runs or tank bottoms where a rear or adjustable-angle connection would not fit. Buyers needing a rear-facing or adjustable stem for horizontal piping should select a different orientation.

Questions about this item

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

The thermometer displays both scales simultaneously, with a range of 20 to 180 degrees Fahrenheit and 0 to 80 degrees Celsius, so you can read whichever unit your process requires without selecting a version.

What temperature range will this thermometer actually show once installed?

It reads from 20 to 180 degrees Fahrenheit (0 to 80 degrees Celsius) with 2-degree Fahrenheit and 1-degree Celsius graduations, giving you the full span marked on the 6-inch scale.

How does the 1/2 inch MNPT connection affect what I can mount it to?

The bottom-mounted 1/2 inch MNPT fitting threads directly into a matching 1/2 inch MNPT thermowell, so the stem sits straight in the process flow without additional adapters.
