The Hart Scientific (Fluke) 9140-A Dry-Well Calibrator has a temperature range of 35 C to 350 C, and it reaches its maximum temperature in 12 minutes. At six pounds, it’s small enough to easily carry in one hand. It’s truly a unique innovation in dry-wells.

The unit has a stability of +/-0.05 C or better and a uniformity of at least 0.4 C in the largest-diameter wells and 0.1 C in the smaller wells. Despite its small size, this unit performs.

Use the display, calibrated to +/-0.5 C, as your reference, or use an external thermometer for maximum calibration accuracy. With three removable inserts to choose from, the Hart Scientific (Fluke) 9140-A is as versatile as it is fast.
