Space saving yet spacious, these undercounter chambers offer 6 cubic feet (170 liters) of capacity and up to 9 square feet (.84 m2) of shelf space. Temperature ranges shown below indicate the capabilities of each chamber, while the temperature uniformity indicates the degree of variation throughout the chamber as measured in a specified medium (water, air). An instrument panel can be added to either side of the chamber to support an optional alarm or chart recorder, or a wall-mounted data pack is available. Other options suitable for these small chambers are listed on the Accessories Sheet. A stacking kit can be purchased to save floor space when multiple chambers are needed.
