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.

A resistance temperature detector (RTD) probe responds to temperature change faster than dial thermometers.

Remotely check temperature on the go. These thermometers have a magnetic-back display for temporary mounting and a thermocouple probe with a 5-ft. coiled cable.

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.

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.

Instead of a dial, these thermometers have an easy-to-read LCD.

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.

Detect hot spots, leaks, moisture problems, and construction defects invisible to the eye.

View temperature readings up to 100 feet from the source. This thermometer includes one temperature sensor with a probe that transmits signals to the wireless monitor. It comes with a calibration certificate traceable to NIST that states it has passed a test for accuracy.

For a longer service life than thermocouple probes and more consistent readings over time, these thermometers have a resistance temperature detector (RTD) probe. They come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy.

Store up to 500 readings on these thermometers and determine temperature within ±0.75° F accuracy.

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.

For use in food-processing applications, this thermometer meets NSF/ANSI standards and includes a thermocouple probe with a pointed tip to pierce dense meats and frozen foods.

Measure the relative humidity and temperature of indoor spaces.

Slip these meters in a pocket or clip them to a belt to take on-site humidity and temperature readings.

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.
