Refrigerator thermometer PC-3300 1 unit

The maximum and minimum temperatures are displayed at all times. The maximum temperature (MAX) and minimum temperature (MIN) will be stored when the battery is inserted or the reset button is pressed. The temperature will be stored until the next time the reset button is pressed or the battery is replaced. You can switch between two types of sensors: the built-in sensor and the external sensor. If no external sensor is connected, the ambient temperature of the unit will be displayed. If an external sensor is connected to the main unit, the display will automatically switch to the measurement value of the external temperature sensor. By using an external sensor, it is possible to measure temperatures as low as -50°C, which is also useful for temperature management in freezers. Measurement range (IN/OUT (°C)): -5 to +50/-50 to +70 Accuracy: 0 to 40°C/±1°C, Others/±2°C Measurement sampling: 1 min/time External sensor: Waterproof JIS C 0920 compliant (IPX4) Body material: ABS resin Size: 67 x 20 x 65 mm Cord length: 3m Power supply: 1 LR44 button battery (included for testing) Battery life: Approximately 1 year when used at room temperature Weight: 50g Comes with tabletop stand and wall hook Accessories: 1 LR44 button battery (for testing), 1 external sensor mounting bracket *The sensor cannot be used underwater.
