What Is The Difference Between The WS-09-C And WS-091-C?

The WS-09-C is intended specifically for refrigerator and freezers. The alarm will sound if the sensor falls bellow or rises above the MIN/MAX limits for more than 10 minutes and the alarm icon is present. This prevents false alarms from sounding when the
refrigerator/freezer door is opened.

The WS-091-C is intended for all other applications.  The alarm will sound if the sensor falls bellow or rises above the MIN/MAX limits and the alarm icon is present.
