Features 1. 4-in-1 function: This is a 4-in-1 multifunctional soil tester. The soil tester can quickly measure soil moisture, pH value, temperature, and sunlight intensity to help better take care of your flowers and plants. By measuring the moisture, pH, and temperature values of the soil, as well as the sunlight level of plants, you can know when to water the soil. 2. Large screen backlit LCD display: The soil meter adopts a large screen LCD display and green backlight, which can easily display and read digital parameters in both day and night. 3. Fast and accurate measurement: The latest probe detection technology can quickly and accurately measure the pH value, moisture, and temperature of soil. The internal light intensity sensor analysis of the instrument can let you know when to water the soil and control the pH value and temperature. And determine whether the plants have sufficient light to scientifically cultivate them better. 4. Easy to use: Simply insert the probe into the soil about 4 inches (10cm) and wait for 10 seconds to read intuitive data, and you will immediately get accurate readings. After use, simply remove the probe from the soil and wipe it clean. 5. Wide range of use: can be used both indoors and outdoors. Plant measuring instruments can be used for your garden, farm, potted plants, succulents, and more.
