Find a refrigerated calibration bath for low temperatures (i.e. –40 °C). Hart metrology baths are well known world-wide for excellent temperature control that maintains excellent temperature stability (±0.0015 °C) and uniformity (±0.003 °C). Models 7008, 7040, 7037, 7011 and 7012 can be used with Hart bath fluids to safely reach high and low temperatures.
- Stability to ±0.0007 °C
- Best digital temperature controller available
- “Super Tweak” function provides set-point resolution to 0.00003 °C
- Excellent for maintaining fixed-point cells

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 five 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 package. 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.
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.
