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 as 100 °C and 122 °C.
