Stalgast Refrigerator/Freezer Thermometer 620110

A refrigerator/freezer thermometer measures the air temperature inside cold storage units, ensuring food safety by tracking conditions that prevent bacterial growth or spoilage. Unlike built-in gauges, which may reflect only the sensor location, this standalone device gives a direct reading of the actual environment where food is stored. The thermometer responds to changes in temperature through a bi-metallic coil or liquid-filled sensor, expanding or contracting to move the indicator needle across the scale. This mechanical principle requires no power, making it reliable for continuous monitoring even during power interruptions or defrost cycles.

To use the thermometer, the operator attaches the suspension bracket to a shelf, wall or rack inside the refrigerator or freezer. The unit should be positioned away from the door, evaporator coils or fans to avoid false readings from draughts or direct cold spots. Once hung, the thermometer settles to the ambient temperature within minutes, displaying the current reading on the dial. The operator checks the temperature regularly, comparing it against the required storage range for fresh, frozen or chilled goods. If the reading falls outside safe limits, adjustments to the unit's settings or maintenance may be needed.

The thermometer is housed in a stainless steel casing, chosen for its resistance to corrosion and moisture common in cold, humid environments. The suspension bracket allows flexible placement, ensuring the device can be positioned at eye level for easy reading without opening the unit. The temperature range of -40 to +40 °C covers the full spectrum of professional cold storage, from deep-freeze conditions to chilled holding temperatures.

The scale is calibrated to show both positive and negative temperatures, allowing the same device to monitor refrigerators, freezers or blast chillers. The -40 to +40 °C range means the thermometer can track everything from frozen goods to ambient storage, eliminating the need for separate devices. The stainless steel housing protects the internal mechanism from condensation and ice build-up, ensuring consistent performance in high-moisture environments.

Cleaning is straightforward: wipe the housing and dial with a damp cloth and mild detergent, avoiding abrasives that could scratch the surface or obscure the markings. The suspension bracket can be removed for thorough cleaning if needed. Regular checks ensure the thermometer remains accurate and legible over time.
