Need portability and stability? Hart Micro-Baths have both. And, while many have tried to duplicate it, none of them use proprietary Hart Scientific controllers, so none can 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 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 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 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-temp safety cutout.
