Professional 6 in1 Soil Monitor: Understand your garden's needs in seconds! This Soil tester provides accurate readings of Soil Moisture, pH, Fertility, Sunlight, Temperature, and Ambient Humidity.It delivers a complete soil analysis within 6 seconds, providing immediate and reliable data for home gardening, balcony plants, greenhouses,vegetable plots, flower beds and professional farming. With 3 High-precision Replaceable Probes: Built for durability and a long service life.The Soil Test Kit includes three metal probes that are more corrosion-resistant than standard materials.Their high conductivity and sensitivity greatly enhance the speed and accuracy of moisture and pH analysis.If the probes wear out or get d, you can affordably replace them without having to discard the entire tester. Intuitive Operation: Simply glide a switch to easily measure light levels, soil moisture, pH, fertility, and view air temperature and humidity on a stable digital screen (That is, when you select which channel, the pointer dial will display the corresponding value). The rotating head design allows you to adjust its angle at 0°–90°, so you never have to stoop down to read the scale. Guidance For Accurate Readings: For best results based on the meter's function: Insert the probes about two-thirds of their length into moist soil.This ensures proper electrical contact for pH, Fertility, and Moisture readings. Avoid rocky, very hard, or pure sandy soil.Do not test liquids or leave the probes in the soil long-term. After each use, always clean and dry the metal probes thoroughly to maintain sensor accuracy and longevity. Notes: 1.Do not use to test water or other liquids. 2.Do not use in rocky or excessively hard soil.3.This detector is not suitable for sandy or loose soils.4.Keep the probes clean and dry before and after use; do not leave them in the soil for extended periods. 5.During use, insert to two-thirds of the probe depth; shallow insertion will not provide a reading.6.Do not force them into the soil to avoid .7.Do not take repeated readings at the same exact spot.
