Description
Chlorophyll Content Measurement Chlorophyll Meter with 0.0-99.9SPAD ±1.0SPAD Introduction: According to the absorption law of chlorophyll spectrum, the chlorophyll analyzer uses two different light-emitting tubes to illuminate the leaves, and calculates the relative content of chlorophyll or the degree of greenness in the leaves by measuring the intensity of the light passing through the leaves, so as to provide reliable, reasonable and timely fertilization. It is widely used in scientific research and production guidance in agriculture, forestry, plants, etc. Specifications: 1. Measurement object: terrestrial plant leaves 2. Measurement parameters: chlorophyll and leaf temperature, humidity, nitrogen Nitrogen range: Full Nitrogen accuracy: ±5% Chlorophyll range: 0.0-99.9 SPAD Chlorophyll accuracy: ±1SPAD Leaf temperature range: 0-60℃ Leaf temperature accuracy: ±1℃ Moisture range: 0-5g/cm² Moisture accuracy: ±3% 3. Measurement principle: optical density difference at two wavelengths of 650nm and 940nm 4. Measuring range: 0.0-99.9 SPAD 5. Measuring area: 2mm*3mm 6. Measurement accuracy: within ±1.0 SPAD units (at room temperature, the SPAD value is between 0-50) 7. Repeatability: Within ±0.3 SPAD units (SPAD values between 0-50, keep the measurement position unchanged) 8. Measurement time interval: less than 2 seconds 9. Memory: 16GB of memory, can calculate/display average values, and remove outliers 10. Maximum sample thickness: 1 mm 11. Sample insertion depth: 10 mm 12. Power supply: 4.2V rechargeable lithium battery 13. Battery capacity: 2000 mAh 14. Weight: 250g 15. Dimensions: 140×85×45mm (length×width×height) Features: Data measurement: extremely high measurement accuracy and repeatability (accuracy: ± 1.0 SPAD, repeatability: ± 0.3 SPAD), comparable to imported brands, or can be calibrated by customers based on leaves with known chlorophyll content or standard samples Data grouping: The instrument can automatically group the data, and can automatically calculate the average value of each group of data. The measured data of the same blade can be automatically grouped into a group, which is convenient for viewing each measurement data and the average value of this group of data, effectively avoiding the confusion of measurement data of different blades. 16GB large storage is used, so the number of groups and the data of each group are not limited Data storage: 16GB large storage space, huge amount of data storage Data browsing: You can browse the measured data, the average value of each group of data and delete abnormal values on the instrument at any time. The data situation is more intuitive Data export: multi-function USB interface, which can realize data export and charging function, can connect the instrument and computer directly, data is exported in EXCEL format, no need for host computer software, simple and convenient operation Display: High-contrast LCD display, data can be clearly displayed even under strong light The measurement is fast and simple: only need to insert the blade and close the measuring probe when measuring, no need to pick the blade, and it will not affect the normal growth of the crop. analysis results of Battery consumption: low power consumption mode design, built-in high-capacity lithium-ion rechargeable battery, energy saving, environmental protection and convenient for outdoor operation Instrument charging: excellent charging management design, compatible with most USB port (5V) chargers, with anti-overcharging function Easy to carry: 250g weight, easy to carry to the field for in vivo measurement
