B.O.D. Thermoelectric Cooled Incubator B.O.D. Thermoelectric cooled incubator. Innovative Peltier cooling technology eliminates the need for a refrigeration compressor. SRIP series use over 70% less power than alternative models and reduce room air conditioning loads by 75%. Includes strong shelves, which eliminates sagging. Large SRI20P incubator is optimized for high-volume sample and drying applications.SRIP Incubators meet APHA specifications for Biochemical Oxygen Demand (B.O.D.) and include a mechanical convection system to ensure even air distribution, digital temperature set controller, over-temperature limit control, door ajar alarm, and a digital temperature display. A one amp interior outlet allows use of shakers, stirrers, roller bottles or other apparatus. Units are supplied with adjustable leveling feet. Low Temperature Incubators are ideal for testing of sewage and wastewater, as well as other low and room temperature applications.Features: Microprocessor Control System P.I.D.
