DOrorO Portable Chlorophyll Meter Machine, Digital Chlorophyll Analyzer for Testing Plant Chlorophyll, Handheld Chlorophyll Tester, 2000MAH Lithium Battery,with USB Data Export,B

Plant Nutrition Tester can instantly measure the relative chlorophyll content of plants (in SPAD), providing a basis for precise plant fertiliser irrigation, thus avoiding waste and environmental damage caused by over-fertilisation. It helps to increase the use of nitrogen fertiliser and provides reliable soil and crop information for precision agriculture.>>> Specification：Name：Plant Nutrition TesterModel：YLS-A/ZZYMeasurement time interval: less than 3 secondsData storage medium: SD card storageData storage capacity: 2GBPower supply: 4.2V rechargeable lithium batteryBattery capacity:2000mahWeight:250gDimensions:140x 85x 45mm(L×W×H)Working and storage environment:0℃-50℃; 85% relative humidityYLS-A (Style A)Check item: ChlorophyllMeasuring range:0.0-100 SPADMeasuring area:2mm*2mmMeasurement accuracy: ±1.0 SPADRepeatability:±0.3 SPADZZY (Style B)Check items: chlorophyll, nitrogen content, leaf surface temperature, leaf surface humidityNitrogen range: whole rangeNitrogen precision: ±5%Chlorophyll range: 0.0-99.9SPADChlorophyll accuracy: ±1.0 SPADLeaf temperature range: 0-60°CLeaf temperature accuracy: ±1°CMoisture range: 0-5g/cm2Moisture accuracy: ±3%>>> Packing list：1*Host1*Charger1*Data cable1*Instruction manual1*Portable aluminium caseIf you have any problems during use, please feel free to contact us.

• ☂【CHLOROPHYLL TESTER】: Plant chlorophyll meter, by measuring the light transmittance coefficient of leaves in two wavelength ranges, 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, and protect the environment.
• ☂【MEASUREMENT RANGE】: Chlorophyll: 0.0-99.9 SPAD, Measuring Area: 0.0-100 SPAD; Whether in an agricultural setting or a university botany laboratory, measure chlorophyll like a pro.
• ☂【QUALITY MATERIAL】：Backlit LCD display, clear and intuitive readings. Built-in 2000mAH rechargeable lithium battery, USB charging. High-quality plastic shell, compact and convenient, comes with a portable bag for easy storage.
• ☂【ACCURATE MEASUREMENT】: Your plants are precious. Our meters' non-destructive testing methods allow you to detect the health of your plants without causing a bit of harm. Built-in highly intelligent microprocessor, high-precision instrument, accurate measurement, small error and fast processing speed.
• ☂【OPERATION IS SIMPLE】：Farewell to the traditional detection method, the detection of undamaged live plants, The data can be displayed when the probe head clamps the leaf surface, without affecting the growth of the plant.
