Hart 6102, 7102, 7103 Micro-Baths

Hart Micro Baths are designed to give you give extreme stability along with portability.

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.

Hart 6330, 7320 Compact Constant Temperature Calibration Baths

The 6330 bath delivers all the high temperatures you need up to 300°C (572°F). With stability and uniformity at 300°C better than ±0.015°C and ±0.020°C respectively, calibrations can easily be performed at this high temperature with total uncertainty better than ±0.05°C. At lower temperatures, stability and uniformity are even better.

The 7320 Model covers low temperatures from –20°C to 150°C. From –20°C to 30°C, stability is an impressive ±0.005°C with uniformities also better than ±0.005°C. No utility bath performs as well as the 7320 at critical temperatures below 0°C, at typical room and body temperatures, and even at important higher temperatures such as 100°C and 122°C.

Hart 7380 Metrology Bath

When you need an ultracold temperature source for your laboratory, don’t settle for a chiller or cheap utility bath from a company that really doesn’t understand metrology. Hart’s model 7380 Compact –80°C Bath is a real metrology bath—designed, manufactured, and used by the largest temperature calibration company in the world.

The 7380 covers temperatures quickly from –80°C to 100°C. Cooling time to –80°C is only 120 minutes and stabilization time is just 6 minutes.

Two-sigma stability is ±0.006°C at –80°C. Uniformity, measured as the difference between the warmest and coldest locations in the bath tank, is also within ±0.008°C at –80°C.
