Feature:1. Hand Held Type: The tachometer adopts a hand held design, with small size and light weight, which is convenient for users to carry.2. Material: The probe adopts a needle shaped probe design, and the material is stainless steel, which has good corrosion resistance and toughness. The probe plug in design ensures accurate measurement and reliable performance.3. High Accurate: The product has high measurement accuracy and quick response speed. A low power LCD screen is used to display the measured values.4. Real Time Monitoring: Real time monitoring of soil components, which can detect a variety of organic components in the soil. Low threshold, few steps, fast measurement, no reagents, unlimited detection times.5. Battery Powered: Battery powered, LCD digital display, interface parameter function display is clear, the battery can be replaced (shipping without battery).Specification:Item Type: Soil Moisture MeterProduct Material: Stainless SteelProduct Size: Approx.18.6cm / 7.3inApplicability: the Rapid Tester is Widely Used in Fields Such As Farmland Production, Soil Research, Greenhouse Planting, Orchard Nursery, Horticultural Planting, Tree Planting, Pot Planting, Etc.Power Supply: AA Batteries, Alkaline Zinc Manganese Batteries (Three) (Battery Not Included)Working Hours: According to the Use of 20 Times a Day, It Can Be Used Continuously for 1.3 Years (The Specific Use Situation Depends on the Number of Use Per Day and the Length of Time)Quiescent Current: Less Than 50aAverage Working Current: 13mAResponse Time: <1sWorking Temperature: -20 ~ 60Protection Level: IP54Moisture Parameters:Range: 0-100%Resolution: 0.1%Accuracy: 2% within 0-50%, 3% within 50-100%Conductivity Parameters:Range: 0-10000 us/cmResolution: 1us/cmAccuracy: 3%Weight: Approx.204g / 7.2oz.Package List:1 x Soil Moisture Meter Note:Note: 1. The probe must be in full contact with the soil and compacted to ensure data accuracy. 2. The soil rapid tester only tests dirt and soil, and is not suitable for dry flour, small stones, organic wood chips, liquid particles, etc. 3. In order to improve the accuracy of the test results, please use the method of multi point test to get the average value during the test. 4. When using, pay attention to the test point not to touch the stone, do not use too much force, otherwise it will easily damage the electrode. It is not suitable to be inserted in the soil for a long time, as it is easy to oxidize. 5. After the measurement, clean the soil particles on the surface of the probe with gauze in time to keep the probe dry.
