When you only need a circulator or some type of utility bath to control a process within a few degrees or to maintain biological test samples, just about any bath will do. But when you’re doing precision thermometer testing, and stability and uniformity are critical to the success of your work, you need a Hart Scientific metrology bath. They are the most stable and uniform of any in the industry. These four new compact baths are top of the line.
The Model HR6330 bath delivers all the high temperatures you need up to 300°C (572°F). With stability and uniformity at 300°C better than ±0.015°C and ±0.020°C respectively, calibrations can easily be performed at this high temperature with total uncertainty better than ±0.05°C. At lower temperatures, stability and uniformity are even better. The HR6330 is only 12 inches wide and less than 19 inches tall, so it fits easily onto a benchtop without consuming precious space.
The Model HR7320 and HR7340 baths cover your needs for low temperature calibrations. The HR7320 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 also better than ±0.005°C. No utility bath performs as well below 0°C or at critical room and body temperatures – or even at important higher temperatures such at 100°C and 122°C.
For ultra cold temperatures, the HR7380 reaches -80°C quickly and maintains a two-sigma stability of ±0.006°C when it gets there. The HR7380 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 Calibrate-it software, automated calibrations can run unattended. |
