Comparison calibrations require a heat source that’s stable and uniform, and for moderately high temperatures nothing provides a better heat source than a Hart oil bath.
Hart oil baths are stable to ±0.001 °C and do not require calibration blocks or use of special calibration techniques to achieve that stability. The specifications of all Hart baths are “true” specifications representing the performance you can expect to achieve in your lab under your operating conditions. Other companies advertise specs that they know you will never see in your lab. When their baths fail to perform, they blame it on you.
Hart baths are built using a unique tank design that guarantees the best uniformity possible in a liquid bath. This, coupled with the industry’s best-selling digital bath controller, achieves uncompromised performance and ease of use.
Not only does Hart’s digital controller have features like its “Super-Tweak” high-resolution mode so you can dial in the exact temperatures you want, it also lets you completely automate the calibration process using your PC and Hart’s 9938 MET/TEMP II software.
You’ll love these baths, and once you’ve got one you’ll never buy anything else. There’s a bath to match any temperature range, depth, price, and performance you need.
Hart sells a complete selection of fluids for your bath. You can find these here.

Interface-it software and RS-232 computer interface are available for setting bath temperature via remote computer. For IEEE-488, add the 2001-IEEE to the automation package.
|†External cooling required for operation below 40 °C. Cooling coils are built into the bath walls. Tubing ports are accessible at the back of the bath for circulating chilled fluid or shop air to boost cooling.|
