Soil fertility detector, for analyzing nitrogen, phosphorus and potassium, soil pH and EC tester, soil acdometer test

General Description: This 2-in-1 multi-function soil fertility detector analyzes nitrogen, phosphorus, and potassium levels, and also tests the soil's pH and electrical conductivity (EC). Compact and lightweight, this device is easy to transport and use directly in the field, whether in a garden, greenhouse, farm, or orchard. Technical Specifications: pH Range: 1 to 9 (acidic to alkaline) Test Mode: Fertility and pH Electrode Dimensions: Greater than 60 mm Reading Time: Approximately 10 seconds for fertility, 1 minute for pH Installation: Remove approximately 5 cm of topsoil and rake the soil to a depth of 13 cm. Moisten the soil with water (preferably rainwater or distilled water) before testing. Clean the probes with a cloth before use. Operation: To test fertility: Insert the electrode into the soil, wait 10 seconds, and read the value. To test the pH: insert the electrode into the soil, wait 1 minute, and read the value. Record the data after each test. Clean and dry the probes after use.
