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

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

For accurate readings in high-vibration environments, these thermometers have a silicone-filled dial that keeps the pointer from fluttering.

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 detachable brass thermowell covers the thermometer stem to protect it from vibration, corrosion, shock, and pressure.

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.
