Wherever you go with your Micro-Bath, you can count on its performance.  Each model is stable to ±0.03°C or better, depending on the fluid you use.  Uniformity is ±0.02°C or better for low uncertainties using a reference thermometer.  Display accuracy has been improved to ±0.25°C for quick calibrations without a reference thermometer.  In short, you get the stability and precision of a liquid bath in a dry-well-sized package.  Hart Micro-Baths are maximized for true fluid-bath performance.

With a 1.9-inch-diameter, 5.5-inch-deep tank, a Micro-Bath can calibrate any type of sensor including short, square, or odd-shaped sensors. The problems of fit and immersion are virtually eliminated by using a fluid medium rather than a dry-block calibrator.  Micro-Baths are perfect for liquid-in-glass and bimetal thermometers.

All Micro-Baths have RS-232 ports, come with our Interface-it software, and can be used with Hart’s MET/TEMP II software.  Also included are contacts to calibrate a thermal switch, eight set-point memory storage, ramp-rate adjust, and over-temperature safety cutout.

Micro-Baths are CFC-free, and also compressor-free.  That’s right—no heavy, noisy compressor to lug around.  We achieve our temperature range and stability with only one moving part.  This means more durability and less weight.

Hart manufactures and sells temperature calibration baths of every size and shape, and now we have the smallest and lightest baths in the industry to go with the dozens of other models we make.
