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.

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

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.
