Hart Scientific’s temperature calibration baths are known around the world as the best calibration baths made. If you’re looking for a cold bath, no one gives you more choices than Hart.

These six baths operate at temperatures as low as –40°C, and each one is built using CFC-free refrigerants. Hart’s proprietary controller design and unique tank construction produce bath stabilities to ±0.001°C or better. These baths are so stable and uniform that national labs use them for comparison calibrations and fixed-point cell maintenance. 

Each bath (except the 7011) is fully automatable with a bath interface package and Hart’s MET/TEMP II automation software packages. When we automate a bath, we automate it completely with computer-controlled solenoid valves for precision balancing of the heating and cooling system. MET/TEMP II performs all calibration tasks automatically, using your PC. 

With a Hart cold bath, you can forget external coolants. Internal refrigeration systems are all that’s needed to reach each bath’s coldest temperature. Most cold baths may be ordered with an optional pumping lid for supplying external cooling requirements. 

Not only are these the best-performing calibration baths in the industry, they’re also the most reasonably priced. Hart is the largest manufacturer of temperature calibration baths, and larger volume means better pricing. 

Each bath has unique characteristics that make it perfect for specific jobs. Some baths are excellent for SPRTs, some are great with thermistors, and some are perfect for maintaining triple point of water cells. A 7008IR bath can even be used to maintain the temperature of a blackbody cone. 

Regardless of your application, Hart has a bath that gets the job done, and done better than anyone else can do it. Call us today and tell us about your application.
