Find a refrigerated calibration bath for low temperatures (i.e. –40 °C). Fluke Calibration metrology baths are well known world-wide for excellent temperature control that maintains excellent temperature stability (±0.0015 °C) and uniformity (±0.003 °C). Model 7040 can be used with Fluke Calibration bath fluids to safely reach high and low temperatures.
Fluke Calibration’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 Fluke Calibration.
This bath operates at temperatures as low as –40 °C, and is built using CFC-free refrigerants. Fluke Calibration’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.
The bath is fully automatable with a bath interface package and Fluke Calibration’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 Fluke Calibration 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.
