Calibrators

Need portability and extreme stability? Hart Micro-Baths have both. We 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.

Available in single or dual pressure ports. Ranges available from vacuum to 16 psig to 0 to 5,000 psig. Intermediate ranges are available by looking at the Range Select feature and choosing your preferences. All wetted materials are SS or TFE coated.
