Description: Product Name: Soil Acidity/Humidity Tester. This 2 in 1 Soil Tester is designed to measure the PH acidity and humidity levels in different types of soil. It's a must have tool for plantations, gardens, orchards, field production, lawns, and any soil related areas.High Precision: Soil PH Tester equipped with a metal detection sensor that can quickly and accurately detect and analyze soil moisture and pH values. The tester has a resolution of +0.2PH and can measure pH levels from 3-8pH; Humidity from 10%-80%.Easy to Use: With its metal button for switching between pH/humidity measurements, this tester is user friendly. Simply insert the detector (95mm length) into the soil to get accurate readings.Unique Design: This product operates through a hardware system centered around the metal sensor which generates weak currents through oxidation reduction reactions when in contact with soil, driving corresponding units of different pH values and humidity levels on the current meter (no need for batteries or other external power sources).Material & Durability: Soil Moisture PH Meter is made of reliable plastic metal materials that ensure longevity even with regular use in various environments.?The detector of the instrument should not be inserted into the soil for too long to avoid oxidation damage and damage to the surface of the detector. After measurement, the soil particles on the surface of the detector must be wiped off with a scouring pad in time. Specification: Material: Metal Plastic Package Includes: 1 Soil?Moisture PH Tester1 English User Manual Note: Please allow slightly errors 1-2cm differences due to manual measurement.
