Supco Refrigerator Thermometer - ST03

Improve refrigerator air or water quality with the correct replacement filter using this Supco Refrigerator Thermometer - ST03. Filters should be matched by part number, filter housing style, and connection type rather than by appliance brand alone.

ST03 is a refrigerator / freezer thermometer. It has a round dial, stainless steel construction, Fahrenheit and Celsius scales, hang-or-stand placement, and a -20��F to 80��F range.

Fitment / What To Verify: Confirm you need an internal refrigerator/freezer thermometer rather than a probe thermometer or service meter. Placement inside the cabinet affects readings.

Please confirm fitment with your refrigerator model number and original filter part number before ordering.
