Chlorophyll True Value Tester IN-YL300

Chlorophyll True Value Tester

I. Instrument Introduction:

Chlorophyll a and b detector is a non-destructive testing equipment that obtains the absorbance of specific wavelengths of plant leaves through a specific light source and photoelectric sensor, and calculates the accurate chlorophyll a and chlorophyll b content. It is portable and lightweight, and can be used in the field to quantitatively detect non-isolated plant leaves, which can be used to help determine abnormalities in plant physiology and ecology. The instrument provides true values of chlorophyll a and chlorophyll b content rather than SPAD values.

2. High measurement accuracy, built-in anti-glare interference system.

3. One operation can determine all parameters at the same time, chlorophyll a, chlorophyll b, chlorophyll total value, nitrogen content, leaf temperature, leaf humidity, 6 parameters of the same screen display at the same time, and can be stored at the same time.

4.16GB large storage space, data can be stored, viewed and 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, save and clear the historical data on the instrument.

7. GPS positioning function: real-time display of satellite positioning latitude and longitude, clear current detection position.

8. Instrument built-in 4G wireless transmission module (complimentary two-year data flow), support for real-time uploading of data in the field environment, the test results can be directly transmitted to the exclusive cloud agricultural data centre, the allocation of the enterprise's exclusive cloud agricultural data centre account, the account centre can view the uploaded data.

9. Cloud agricultural data centre can retrieve historical data according to any time period, can view the measurement time, chlorophyll a/b/total value content, nitrogen content, leaf temperature, leaf humidity, GPS positioning information and other data, display each parameter process curve trend, maximum value, minimum value view, zoom in, zoom out function, support for online downloads, EXCEL export, analysis, printing

10. High-contrast LCD display, bright light can also clearly display the data
