The MASTER-BILT 19-13958 is a digital thermometer designed for use in commercial refrigeration and cold storage applications. It includes a 6-foot sensor cable that allows flexible probe placement inside a refrigerated cabinet, walk-in cooler, or freezer compartment. Operating on 110 volts at 50/60Hz, this unit provides a reliable electronic temperature readout to help service technicians and operators monitor conditions accurately. It is installed by refrigeration technicians and commercial appliance service professionals as an OEM replacement or upgrade component in MASTER-BILT equipment.
This thermometer is suited for commercial refrigeration environments where accurate temperature monitoring is required. Typical installations include reach-in coolers, under-counter refrigeration units, and similar MASTER-BILT commercial appliance configurations. The extended 6-foot sensor gives technicians the flexibility to route the probe to the most representative monitoring location within the cabinet or conditioned space, supporting both service and regulatory temperature verification needs.
Designed as an OEM-style replacement digital thermometer for MASTER-BILT commercial refrigeration appliances and cold storage equipment.
Installation should be performed by a qualified refrigeration technician or commercial appliance service professional. Disconnect power to the unit before removing the existing thermometer or routing the sensor cable. Route the sensor probe to an appropriate location within the refrigerated space, avoiding direct contact with evaporator coils or airflow obstructions. Verify supply voltage matches the unit rating of 110 volts before restoring power.
