Run the external sensor cable out of a window or through a small opening to position the sensor outdoors, or place the waterproof sensor inside a refrigerator, freezer or aquarium as required. Use the max-min function to record peak temperatures and reset it manually when you want to start a new observation period. Mount the device on a wall using the integrated hanging slot or position it on a table or window sill.
Usage recommendations
Locate the outdoor sensor in a shaded and sheltered position to avoid direct sunlight or precipitation affecting the reading. For refrigerator or aquarium use, ensure the sensor is placed where it will not contact moving parts or heating elements. Replace the AAA battery when the display dims or readings become unstable. Clean the housing with a soft, dry cloth and avoid aggressive cleaning agents; do not immerse the main unit in water.
