Mountable Thermometers

Threaded Thermometers

Monitor process temperature with these thermometers that install directly into threaded tank and pipe connections.

Compact Threaded Thermometers

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

Side-Connection Threaded Thermometers

For installation in tight spaces, these thermometers have a side connection and face upright for easy viewing.

Threaded Thermometers with Calibration Certificate

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

Deep-Reach Threaded Thermometers

An extra-long stem extends into deep tanks and hard-to-reach areas.

Minimum/Maximum-Indicating
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.

Vibration-Resistant Threaded Thermometers

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

Heavy Duty Threaded
Thermometers with Thermowell

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

Threaded Thermometers with
Corrosion-Resistant Stem

Monitor the temperature of corrosive fluids in harsh conditions.

Vibration-Resistant Threaded
Thermometers with Calibration Certificate

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.

High-Accuracy Threaded Thermometers
with Calibration Certificate

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.

Food and Beverage Threaded Thermometers

Dry dials with acrylic lenses eliminate the risk of contamination in case of breakage, so these thermometers are often used in food-processing applications.

Clip-On Thermometers

Attach these thermometers to the rims of tanks, trays, vats, and other containers.

Magnetic-Back Surface-Temperature Thermometers

Check the surface temperature of tanks, generators, annealing ovens, boilers, and other metallic equipment.

Minimum/Maximum Indicating Magnetic-Back
Surface-Temperature Thermometers

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

Food and Beverage Thermometers
with Sanitary Quick-Clamp Connection

For dairy, food, and beverage applications that require frequent cleaning, these 3-A certified thermometers have a sanitary quick-clamp connection for easy removal.

Panel-Mount Thermometers

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

Pipe-Mount Surface-Temperature Thermometers

Pocket Thermometers

Floating Pocket Thermometers

A removable rubber float keeps these thermometers on the surface of liquid-filled containers for hands-free temperature readings.

Food and Beverage Pocket Thermometers

For use in food processing and preparation applications, these thermometers meet NSF/ANSI standards.

Glow-in-the-Dark Pocket Thermometers

The luminescent dial face provides clear temperature readings in low-light conditions.

Pocket Thermometers

Tuck these thermometers into your pocket for on-the-go readings.
