Units come standard with microprocessor temperature controller with audible and visual alarms, digital temperature display, remote alarm contacts, keyed door locks and leveling legs.
Great units, used for chemical storage in industrial area. Various set points allow you to tune the unit to your exact needs. Holds temperature very well. Multiple temp sensors including product sample temp is a great feature. May seem a little expensive, but a great deal on laboratory grade refrigeration units. We bought 2 for our shop and are very pleased.
