- Accurate temperature and humidity monitoring for aquariums, fish tanks, refrigerators, cars, and more. Helps you maintain safe water temperatures, stable storage conditions, and comfortable environments with reliable readings. - Compact size with hanging hook and bracket for easy placement on walls or countertops. Flexible mounting saves space and makes it simple to position the sensor where you need it. - Waterproof probe for submerging into fish tanks to measure water temperature accurately. Direct immersion provides precise water readings even in wet environments. - Max/min function displays the highest and lowest temperature and humidity values memorized. Quickly assess fluctuations and identify trends over time. Use scenarios - Aquarium maintenance: submerge the probe in the tank to monitor water temperature continuously and use max/min to detect temperature swings that could stress aquatic life. - Food storage: place in a refrigerator to monitor internal temperature and humidity, helping preserve perishables and prevent spoilage. - Car or room monitoring: mount on a wall or place on a countertop in a vehicle or office to track climate conditions and ensure comfort or protect sensitive equipment.
