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.

Models 7320 and 7340 Also featuring large work areas, our Model 7320 and 7340 baths cover your needs for low temperature calibrations. The 7320 covers a range from –20°C to 150°C and the 7340 reaches even colder temperatures to –40°C. Below 0°C, these baths maintain an impressive stability of ±0.005°C with uniformities better than ±0.006°C. No utility bath performs as well as Hart’s compact baths below 0°C or at critical room and body temperatures—or even at important higher temperatures such at 100°C and 122°C.
