When you only need a circulator or utility bath to control a process within a few degrees or to maintain biological test samples, talk to a utility bath manufacturer. But when you’re doing precision thermometer testing, and stability and uniformity are critical to the success of your work, talk to us. 

Hart Scientific has been making the world’s best-performing temperature baths for almost two decades. With our proven heating/cooling designs and hybrid analog-digital controller, Hart baths apply the most effective technologies that are commercially feasible. These four compact baths are no exception. 

Model 7380 For ultracold temperatures, the 7380 reaches –80°C quickly and maintains a two-sigma stability of ±0.006°C when it gets there. The 7380 is a true metrology bath, not a chiller or circulator. With uniformity to ±0.008°C, comparison calibration of temperature devices can be performed with high precision. 

Each bath includes an RS-232 serial interface and our Model 9930 Interface-it software for controlling your bath from a PC. With a Hart Scientific thermometer readout, such as a Black Stack, and our MET/TEMP II software, automated calibrations can run unattended. 

Hart Scientific doesn’t make chillers, circulators, or so-called utility baths, and utility bath manufacturers don’t make metrology baths. Use the right tools for your work and reap the best possible results. Baths from Hart Scientific are the most stable and uniform of any you’ll find. They’ll give you results no other bath can.
