Chlorophyll Detector, Hand-Held Chlorophyll Analyzer, for Measuring Instantly Relative Chlorophyll Content with Measurement Range 0.0 to 99.9 Spad

Specification:Power supply: 4.2V rechargeable lithium batteryBattery capacity: 800MAHMeasuring range: chlorophyll: 0.0-99.9 SPAD, nitrogen content: 0.0-99.9 mg/gMeasuring area: 2mm*2mmMeasurement accuracy: chlorophyll: within 1 SPAD unit (0.0-50.0 SPAD under normal temperature and humidity), nitrogen content: ±5%.Repeatability: Chlorophyll: Repeatability within ±0.3 SPAD units (0.0-50.0 SPAD measurement position remains unchanged), Nitrogen content: ±0.5 units.Data storage medium: SD card storageData storage capacity: 2GBMeasurement interval: less than 3 secondsWorking and storage environment: -10 -50℃; relative humidity 85%Product size: 140×85×45mmWeight: 250gDue to manual measurement, there may be an error of 1-3cm, I hope you can understand.

• ☑【Measurement range】Chlorophyll: 0.0-99.9 SPAD, Nitrogen content: 0.0-99.9 mg/g, Measuring area: 0.0-100 SPAD
• ☑【Backlit Display】The chlorophyll meter has a backlit LCD display, When measuring, just place the leaves of the plant on the measuring position and wait 2-3 seconds to obtain the measurement data.
• ☑【Multi-Function】The chlorophyll tester can not only measure the chlorophyll content of plants, but also the nitrogen content, leaf temperature and humidity of plants.
• ☑【Working Principle】The multifunctional chlorophyll meter measures the relative content of chlorophyll in leaves by measuring the light transmittance coefficient of leaves in two wavelength ranges.
• ☑【Storage Data】The multifunctional chlorophyll meter has a storage capacity of 2GB and can store multiple measurement data. Even if there is an unexpected power outage, the data will not be lost.
