The 1/4 NPT male back connection fits smaller equipment than other threaded thermometers.

Ensure reliable readings with these thermometers. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

In addition to a pointer that shows the current temperature, these thermometers have a second pointer that indicates the highest or lowest temperature reached.

A thermowell covers the thermometer stem for protection from vibration, corrosion, shock, and pressure.

The included calibration certificate traceable to NIST states that these thermometers have passed a test for accuracy, and the silicone-filled dial keeps the pointer from fluttering in high-vibration environments.

The most accurate threaded thermometers we sell, these come with a calibration certificate traceable to NIST that states they’ve passed a test to fall within ±0.5° F accuracy.

For mounting on instrument and control panels, these thermometers have a back flange.

In addition to showing current surface temperature, these thermometers have pointers to indicate the minimum and maximum temperatures since the last reading.
