Thermo Scientific Revco Ultima Plus Ultra Low Temperature Freezer ULT2586-10-D48**This ultra-low temperature freezer was run over a couple days and was able to reach maximum low temperature of -73c. Unit has slight wear from normal use. Bottom right side corner panel is slightly bent. Rear panel connector is missing cover plate. See photos for further details.Programmable microprocessor control, patented refrigeration system, and state-of-the-art electronics ensure the highest level of sample protection. Plus, these units offer up to 20% more heat removal capacity, 15% less power consumption and 15% less heat emission than comparable ultra-low temperature freezers.Precise temperature control from -50 to -86C, adjustable in 1C incrementsDoor-mounted, eye-level control panel with easy-to-read LED display and touchpad data entryMonitoring and Alarm SystemsOn-board diagnostics continuously monitor sensors to ensure proper performance.Control Setpoint sets cabinet temperature, Cabinet Temperature displays the temperature.Automatic Incident Monitor (AIM) identifies temperature deviation due to power or temperature failure.Time Delay feature delays restart after power failure.Voltage Buck/Boost corrects line voltage into the unit.Low Voltage Surge Protection minimizes voltage spikes.Life-Guard Alert monitors compressor performance automatically adjusts to internal and external conditions.Clean Filter, Alarm Battery Low, and Voltage indicatorsBattery backup supplies control panel in case of power failureKey-operated main power and alarm switch locks temperature and alarm setpointsAudible/visual power and temperature failure alarms automatically activate during a temperature deviation.Extreme Ambient Alert warns if room temperature may affect performance.Alarm Test simulates temperature alarm condition.Alarm Reset mutes audible alarm and resets AIM.Remote alarm contacts for external alarm/monitoring systemConstructionHigh-strength steel cabinet with corrosion-resistant coatingMinimum 5in.
