This 4.9cu ft capacity undercounter model Revco® REL404A high-performance laboratory refrigerator has a solid door with three adjustable interior shelves. It has an adjustable temperature range between 1° and 8°C (factory preset at 4°C), with automatic defrost and condensate removal. It is microprocessor controlled with digital electronic technology with icon-based controls designed to simplify operation and deliver greater accuracy. It has a large, easy-to-read digital display of temperature within 0.1°C. The graphic themometer is steady green when the temperature is normal, and flashes the top bar for overtemperature and flashes the bulb for undertemperature. The sensor automatically initiates the defrost cycle on demand, eliminating the need for a defrost timer, minimizing frost buildup, and optimizing coil efficiency. The alarm system has audible/visual warnings for temperature deviations or power failure, with a key-operated on/off/alarm on master switch for setpoint security. It has push-button alarm test and remote alarm contacts, with alarm silence, ringback, and auto reset features. It has a controller battery backup system, and alarm setpoints are preset to warn of temperature deviation at 5.5°C overtemperature and 1.5°C undertemperature.
