The meter is a 4in1 design, perfect for testing sunlight intensity, pH value, moisture value, and temperature. The acid-base balance of the soil can directly affect the growth of plants, with measurement ranges of 3.0-9.5H. 5 levels of moisture design, different plants have different water requirements, so with this meter, you can know the soil moisture clearly and adjust the watering amount. Wide applications, it is suitable for use in vineyards, orchards, field production, nurseries, lawns, gardens, flower beds, farmland, and classroom experiments. Features: 4in1 multiple propose design, perfect for testing sunlight intensity, pH value, moisture value, and temperature. There is a highly sensitive extended probe for faster and more accurate detection. It is rustproof and corrosion resistant, suitable for different soil textures, and suitable for various outdoor environments. A large digital display and green backlight allow you to read the index of sunlight intensity, pH value, moisture value, and temperature. The acid-base balance reaction of the soil directly affects the growth of plants, which can make you know the acid-base balance state and measurement ranges of 3.5-9H. With five levels of moisture design, different plants have different water requirements, so with this meter, you can know the soil moisture and adjust the watering amount. With the sunlight intensity detection function, you can decide whether to shade or enhance light to promote photosynthesis according to the plant's growth habits. With a temperature test function, soil temperature determines the living environment of plants, so it is easier for you to build a standard greenhouse with this product, ℃ and ℉ switchable. With a automatic shutdown function, this instrument will turn off the LED after 1.5 minutes of no operation and automatically shut down after 5 minutes of no operation. Wide applications, it is suitable for use in vineyards, orchards, field production, nurseries, lawns, gardens, flower beds, farmland, and classroom experiments.
