Portable Chlorophyll Meter with SPAD & Nitrogen Analysis, Handheld Chlorophyll/Nitrogen/Temperature/Humidity Tester, 2000mAh USB Data Export, for Precision Farming and Gardening B

★The Chlorophyll Meter instantly measures the relative chlorophyll content (in SPAD units) or "greenness" of plants, letting you know the true nitro needs of plants and helping you understand how much nitrogen is missing from the soil, or if nitrogen is over-applied. Using this instrument can improve the utilization rate of nitrogen fertilizer and protect the environment!★Product SpecificationsName: Chlorophyll TesterMeasurement Sample: Various Plant LeavesFunction: Fast Measurement Time, The Screen Directly Displays The Chlorophyll Value, The Instrument Is Compact And Portable, And Can Be Carried To The Field For MeasurementMeasurement Range: 0.0-100 SPADMeasurement Area: 2mm*2mmMeasurement Accuracy: Within ±1.0 SPAD Unit (SPAD Value Is Between 0-50 At Room Temperature)Repeatability: Within ±0.3 SPAD Unit (SPAD Value Is Between 0-50)Measurement Time Interval: Less Than 3 SecondsData Storage Medium: SD Card StorageData Storage Capacity: 2GBBattery: Built-In 4.2V 2000mah Rechargeable Lithium BatteryDimensions: 140×85×45mm (Length×Width×Height)Weight: 250gWorking And Storage Environment ：0℃-50℃; 85% Relative Humidity★Packing ListChlorophyll Meter*1 (A)(Testable Chlorophyll Content)Plant Nutrition Tester*1 (B)(Testable Chlorophyll Content, Nitrogen Content, Leaf Temperature and Leaf Moisture)Instrument Box*12GB Memory Card*1Card Reader*1

• 【HOW IT WORKS】Chlorophyll Meter by measuring the light transmittance coefficient of leaves in two wavelength ranges, the numbers obtained by the display determine the relative content of chlorophyll in leaves, thereby understanding the actual demand for nitrogen by plants, and used to increase plants' demand for nitrogen fertilizers demand and utilization.
