Refrigerated Incubators (often called B.O.D. Incubators or Low Temperature Incubators) are commonly used for applications such as B.O.D. Determinations, Plant and Insect Studies, Fermentation Studies, and Bacterial Culturing. This SRI6P low temperature Incubator has a temperature range of 15°C (with ambient of 25C) to 45°C. The SRI6P space-saving low temperature incubator is ideal for small volume workloads and meets APHA specifications for Biochemical Oxygen Demand (B.O.D.) analysis. Using innovative thermoelectric cooling technology, this SRI3P eliminates the need for a refrigeration compressor. This means that these units use 71% less power than alternative models and reduce room air conditioning loads by 75%. The fully insulated, corrosion-resistant interior chamber is easy to clean. Gentle, continuous forced-air circulation ensures temperature uniformity and reproducible test conditions. Each SRI6P also includes an independent over temperature safety controller, two shelves (adjustable in two inch increments), and a one amp interior outlet to allow the use of shakers, stirrers, roller bottles or other apparatus. This unit has a steel exterior with welded seams and corners and a double-coated, baked enamel finish. It is supplied with adjustable leveling feet and a condensation drip tray. All low temperature incubators are ideal for testing B.O.D. of sewage and waste water, as well as other low and room temperature applications. Features include: Microprocessor control P.I.D. Temperature control LED Display of Setpoint and Chamber Temperature High Limit Thermostat Interior Electrical Outlet Adjustable shelves (2 inch increment) Fan Assisted/Forced-Air Circulation Hermetically Sealed Compressor 24 Month Limited Warranty
