Checking the accuracy of your infrared thermometer is now easier than it's ever been. The new Hart Scientific 9135 IR Calibrator gives you fast, easy, and inexpensive verification of your handheld infrared meters—and its calibration is traceable to NIST.

The 9135 includes three set-points at 50°C, 100°C, and 150°C. Simply select a temperature, wait for the ready light to come on, aim your thermometer at the 1.5-inch-diameter blackbody, and take a reading. Set-points can be reached in less than five minutes, and stabilization time is only three minutes. It doesn't get any easier—or any faster.

Accuracy at any of the 9135's three set-points is better than ±1°C, and stability is within ±0.1°C. Each unit comes with a calibration certificate showing data at each of the three temperatures at no extra charge. Emissivity of the black-body target is 0.95.

At less than two inches thick and weighing less than two pounds, the 9135 is absolutely portable. It fits easily into a tool kit for on-site calibrations. Use it to check an IR thermometer at one temperature or to estimate its span error by checking at 50°C and 150°C.

All of our handheld dry-block calibrators are fast, small, and easier to use than any other manufacturer's dry-well. Now we're doing the same for IR thermometer users.
