Longer and thinner 250mm electrode for deep soil penetrationDurable trouble-free lifeSelf-powered, no batteries requiredaccurate and reliableWaterproof Metal Electrode/ProbeFast pH and moisture measurement readingsCorrect pH readings are important for best results. Crops such as vegetables, flowers and shrubs, trees, weeds and fruits are pH-dependent and depend on soil solutions for nutrients. Soil pH plays an important role in the production of high-quality crops. Most crops cannot survive in soils that are too acidic or alkaline. Knowing the nutrient levels in the soil is to determine what you need to add to the soil to maximize plant growth.Measure pH and moisture levels in different types of soilGreat for fast pH and moisture for gardening, lawn maintenance, greenhouses and vegetable productionMeasuring range: Automatic (1~8)Measuring range: PH(3~8)Colour:blackMaterial:plasticSize:about 39cmPackage Contents:1 x Soil TesterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
