Chlorophyll Meter
I. Use
Chlorophyll meter according to the chlorophyll spectral absorption law, using two different light-emitting tube irradiation leaf, through the measurement of the intensity of light through the leaf to calculate the relative content of chlorophyll within the leaf or the degree of green, so as to provide a reliable scientific basis for reasonable, appropriate and timely application of fertilisers, is widely used in agriculture, forestry, plants and other scientific research and production guidance.
II. Functional characteristics
1. Rapid and non-destructive plant vivo testing, measurement can be inserted into the leaf, no need to pick the leaf, does not affect the normal growth of the crop, you can monitor the leaf throughout the crop growth process, so as to get a more scientific analysis results
2. High measurement accuracy (precision: ± 1.0 SPAD, repeatability: ± 0.3 SPAD)
3. One operation can simultaneously determine all parameters, chlorophyll, leaf surface temperature two parameters of the same screen display at the same time, and can be stored simultaneously
4.16GB large storage space, data can be stored, viewed, exported in groups
5.Multi-functional USB interface, data export and charging function can be achieved, the instrument can be directly online with the computer, data export without the host computer software, you can also choose to use the memory card to export data directly, easy and convenient operation.
6. Data browsing: you can browse historical data and delete abnormal data on the instrument.
7. High-contrast LCD display, which can display data clearly under bright light.
8. Low-power mode design, built-in high-capacity lithium-ion rechargeable battery, with anti-overcharge function, energy-saving and environmentally friendly and convenient for outdoor operation.
9. Built-in Chinese and English bilingual display, one-key switch, seamless.
