Plant chlorophyll meter can measure the relative chlorophyll content of plants (unit SPAD), nitrogen content, leaf temperature and leaf moisture four parameters, four parameters measured at the same time, the same time display. It provides a basis for precise plant fertiliser application and irrigation, thus avoiding waste and environmental damage caused by over-fertilisation. Help you to improve the use of nitrogen fertiliser, provide reliable soil and crop information for precision agriculture. >>>Working Principle: Two LED light sources emit two types of light, one red (650 nm) and the other infrared (940 nm). The two types of light penetrate the blade and hit the receiver. The light signals are converted into analogue signals. The analogue signal is amplified and converted into a digital signal by an analogue/digital converter. The digital signal is processed by a microprocessor which calculates the SPAD value and displays it on the LCD screen. >>>Technical Parameters: Name: Plant Nutrition Tester Model:ZZY Check items: chlorophyll, nitrogen content, leaf surface temperature, leaf surface humidity Nitrogen range: whole range Nitrogen precision: ±5% Chlorophyll range: 0.0-99.9SPAD Chlorophyll accuracy: ±1.0 SPAD Leaf temperature range: 0-60°C Leaf temperature accuracy: ±1°C Moisture range: 0-5g/cm2 Moisture accuracy: ±3% Data storage medium: SD card memory Data storage capacity: 2GB Measuring time interval: less than 3 seconds Power supply: 4.2V rechargeable lithium battery Battery capacity: 2000mah Weight: 200g Dimensions: 140x 85x 45 mm (L x W x H) Working and storage environment: 0?-50?; relative humidity: 85%. >>>Packing list: 1*Host 1*Charger 1*Data cable 1*Instruction manual 1*Portable aluminium case✓?Database?: The storage of the multifunctional chlorophyll meter is SD card storage, which is convenient for reading data.
