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.

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

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