Protect temperature-sensitive materials in refrigerators and freezers with one of these thermometers that sound an alarm and flash the display when temperature rises above your activation point.

Obtain the most accurate readings possible with these thermometers that include a calibration certificate traceable to NIST that states they’ve passed a test to fall within ±0.5° F accuracy.

Externally monitor the air temperature inside freezers, refrigerators, water baths, and incubators. These thermometers come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Since these thermometers operate on indoor light, there’s no need for batteries. The case rotates 180° to obtain the best viewing angle, and the stem pivots 180° to support angled mounting.

Mount this thermometer on pipes in environments with flammable gases, combustible dust, and ignitable fibers.

The long stem reaches the bottom of deep flasks, test tubes, and beakers.

Clip this compact thermometer to your belt loop or keys for temperature readings on the go. It comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy.

The long stem reaches the bottom of deep beakers and flasks, and the water-resistant housing stands up to washdown conditions and outdoor use. This thermometer comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy.

For easier viewing than dial thermometers for food and beverage, these thermometers show readings on an LCD. All meet standards for use in food-processing environments.

Ensure the accuracy of noncontact temperature readings of dangerous and inaccessible surfaces with these thermometers that come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Keep these small thermometers in your pocket or toolkit to spot check the temperature of dangerous, hard-to-reach, and moving surfaces without touching them.

These thermometers are rated for environments where hazardous material is present. They measure the temperature of surfaces without making contact.

These thermometers have a thermocouple probe that can handle extreme temperatures, and come with a calibration certificate traceable to NIST that states they have passed a test for accuracy.

The thermocouple probe measures temperatures up to 500° F, and the thermometer housing meets IPX7 for protection from temporary submersion.

For more accurate and consistent readings than thermometers with thermocouple probes and a longer service life, this thermometer has a resistance temperature detector (RTD) probe.

Designed for laboratory applications, these thermometers determine temperature within ±0.75° F accuracy.

A water-resistant housing and rubberized keypad stand up to washdown conditions and outdoor use.

Measure the relative humidity and temperature of indoor spaces.

To ensure reliable readings on the go, this portable meter comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy.

For comprehensive system checks and quality control, these meters measure a wider relative humidity range than pocket meters and can determine dew point in addition to humidity and temperature.

The USB connection lets you upload up to 32,000 data points to a PC for analysis.

Check temperature, relative humidity, atmospheric pressure, and time with one barometer.
