Feature: 1. Non Corroding Probe: The soil sensor is designed with a probe made of austenitic 304, and has great corrosion proof and toughness. 2. View Record on APP: Mobile applications can view real time moisture data and achieve automatic intelligent irrigation together with our smart garden timer. 3. Temperature and Humidity Measuring: The moisture measurement range is 0‑100%. Moisture accuracy is 0‑50% (± 3%), 50‑100% (± 5%). The temperature measurement range is ‑ 20 ℃‑60 ℃. The temperature accuracy is ± 1 ℃. 4. Compact and Portable: With a sensor length of 7.09 inches and probe length of 2.36 inches, you can carry it around easily; it is convenient for both indoor and outdoor gardening. 5. For Various Gardening Places: Meet the soil moisture measurement of different plantations, and provide all round care for flowers and plants. For example: farm, greenhouse, orchard nursery, garden lawn, potted plants, gardening, etc. Specification: Item Type: Soil Tester Material: ABS Weight: Approx. 144g/5.08oz Sensor Size: 180x46.5mm/7.09x1.83in Probe Length: 60mm/2.36in Power Supply Type: 2xAA battery (excluding battery) Moisture Measurement Range: 0-100% Moisture Accuracy: 0-50% (± 3%), 50-100% (± 5%) Temperature Measurement Range: - 20 ℃ - 60 ℃ Temperature Accuracy: ± 1 ℃ APP Data Response Time: 60S Protection Grade: IP67 Package List: 1 x Soil Tester 1 x Instruction Note: The product can only be used normally if it is connected to a wireless gateway. If the customer has such a gateway, it is unnecessary to purchase it. 1. Install the product at the place where the measurement is required, and insert the sensor probe vertically into the soil. 2. The probe shall ensure full contact with the soil and compaction to ensure the accuracy of the data. 3. The soil temperature and humidity meter only tests soil and soil, and is not applicable to dry flour, small stones, organic wood chips, liquid particles, etc. 4. When inserting the measuring instrument into the soil, please try to insert the probe into the soil as a whole. 5. The depth and compactness of the probe inserted into the soil will directly affect the measured value and cause errors. To improve the accuracy of the test results, please use the method of taking the average value of multi‑point test. 6. When using, pay attention not to touch the stone at the test point, and do not use too much force, otherwise the probe will be easily damaged. 7. When the measuring instrument is not used and stored, do not directly rub the probe surface or scratch it with your hands, keep it clean and dry, and keep it away from magnetic objects and other metal objects.
