Discover our mini heat sources, designed to quickly and accurately verify your thermometer's performance up to 250°C/ 482°F. Simply set the heat source to your desired test point, insert the probe, and confirm accuracy in minutes!With a 0.1° resolution, ±0.5°C accuracy, and rapid temperature stabilization, most industrial thermometers are calibrated...

We have the smallest hot unit, and now a cold unit to test thermometers at 0°C (32°F), which is the most common test point for handheld thermometers. With removable and interchangeable test sleeves, you can adapt this mini dry block from 3/8" diameter to 1/8" diameter and only purchase one...

Check out our new mini heat sources to check your thermometer's accuracy up to 482°F. Simply set the heat source to the desired test point, insert the test probe into the best fitting well, and get a verification of the performance. It's that easy!With a resolution of 0.1°, an accuracy...

Yes, this is really just a printed 32-oz double-walled soda mug. But! A proper ice bath is NOT just a cup of water with some ice thrown in. Although an ice bath is not really rocket science, there still is some science involved. If you do it slightly wrong, or...

The Infrared Comparator Cup provides a stable black body temperature. The comparator cup is an inexpensive way of checking infrared hand-held thermometers against a known reference thermometer. The comparator consists of an aluminum cup with a solid matte black base, the base incorporates a 3.5mm reference thermometer hole for probe...

Store your favorite 12 temperature test points to memory with the MicroCal 1 Plus for quick recall and calibration of handheld meters, controllers, and indicators. Test readouts of the most common Thermocouple types including type K, J, T, R, N, S, and E in simulation mode. Measurement mode is also...

If you rely on thermocouple measurements, you should periodically check the accuracy of your instrument against a traceable thermocouple simulator. Simply plug the Microcal into your meter and step through your preset temperatures or set a precise new temperature using the Up/Down buttons. Our Microcal 2 does the job quickly...

For routine type K thermometer and indicator calibrations, the MicroCheck is the perfect test tool. A single select button scrolls quickly between the 3 factory set calibration points for efficiency. Two models to choose from: 271-018 (0°F, 32°F, 212°F) and 271-019 (32°F, 212°F, 500°F). Each unit includes a 3-point UKAS...

Check the performance of infrared guns quickly and easily with our new IR-500. It reaches an upper temperature of 932°F (500°C) in about 40 minutes. You set the display to the desired temperature, then point, shoot and record. It's that easy. The isothermal 2.25 inch black body target is manufactured...

The platinum RTD is the sensor of choice when a wide range is required with better accuracy than a thermocouple can offer. This meter can be used interchangeably with any of our growing selection of RTD probes. You can also use this meter with sensors of the same type from...

Check or calibrate any RTD instrument. Competing calibrators typically cost 2 or 3 times more. For testing RTD instruments, choose our VA720. Simulate and measure 7 different RTD types in 2-wire, 3-wire, or 4-wire mode. Large single-function buttons and a big digit display make these tools instrument shop favorites.

Until now you would have spent hundreds more to get this level of accuracy in a reference thermometer. Our Reference Thermapen takes lab accuracy into the field. Each unit is factory calibrated at 5 test points and includes a UKAS accredited calibration certificate with test data. A true "system calibration"...

This thermometer is an affordable end to arguments over temperature accuracy. We start with a high stability platinum RTD sensor rated at 1/10th the conformance limits of the DIN specification. The general purpose probe is attached to a high precision resistance thermometer that provides 0.01° resolution. The combination is calibrated...
