The ARS1MLMC is a 1 cu.ft. all-refrigerator. The microprocessor digital thermostat is located in the top control panel, with an LED display of the interior temperature. The buffered temperature probe is encased in glycol to simulate the temperature of the interior's contents, while a second sensor measures interior air temperature for added control. Audible and visual alarms alert you to temperature fluctuations. Additional alarms include an open door alarm, power failure alarm, sensor alarm, and remote alarm contacts in the rear, which allow for alarm forwarding to an external remote alarm system. The pre-installed ½ inch probe hole is located in the right interior wall to allow for additional user-supplied monitoring devices. The digital display provides the min/max temperature in Fahrenheit to the nearest tenth of a degree. Users can switch to Celsius in a few simple steps. Temperature parameters are password protected but can be adjusted aftermarket.
