Need portability and extreme stability? Hart Scientific Micro-Baths have both. Hart Scientific
invented the Micro-Bath. And, while many have tried to duplicate it, none of them use proprietary
Hart Scientific controllers, so none of them deliver performance like a Hart bath. Micro-Baths can
be used anywhere for any type of sensor. The 6102 weighs less than 4.5 kg (10 lb.), with the
fluid. It’s lighter and smaller than most dry-wells, has a spill-proof lid, and is easier to carry than
your lunch. You can take it where you need to go without carts or excessive effort. Micro-Baths
can even be transported with the fluid in them.

Wherever you go with your Hart Scientific 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. Don’t be fooled by competitors who
pour oil into a dry-well and call it a bath. Hart Micro-Baths are maximized for true fluid-bath
performance.

With a 48 mm (1.9-inch) diameter, 140 mm (5.5-inch) deep tank, a hart 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.

The 6102 has a temperature range from 35 °C to 200 °C, the 7102 covers –5 °C to 125 °C, and
the 7103 extends from –30 °C to 125 °C. Stability, uniformity, and accuracy specifications cover
the entire range for each bath, not just the best temperature.

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

You may have noticed we haven’t touted Hart’s CFC-free refrigeration. Yes, cold Micro-Baths are
CFC-free, and also compressor-free. That’s right—no heavy, noisy compressor to lug around.
Hart achieves their 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 they
have the smallest and lightest baths in the industry to go with the dozens of other models they
make.

Look at the specs, price, and value of these portable instruments and you’ll know why Hart
Scientific is the number-one company in this business.
