Chlorophyll True Value Tester YT-YL300

1、 Instrument Introduction:

Chlorophyll a and b detector is a non-destructive testing device that obtains the absorbance of specific bands of plant leaves through a specific light source and photoelectric sensor, and calculates accurate chlorophyll a and chlorophyll b content. It has the characteristics of portability and portability, and can quantitatively detect non detached plant leaves in the wild to help determine abnormal physiological and ecological conditions of plants. This instrument provides real values of chlorophyll a and chlorophyll b content, rather than SPAD values.

3、 Functional Features

1. Fast and non-destructive plant live detection, measurement only requires inserting the leaves, no need to pick the leaves, does not affect the normal growth of crops, can monitor the leaves throughout the crop growth process, and obtain more scientific analysis results

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

3. One operation can simultaneously measure all parameters, including chlorophyll a, chlorophyll b, chlorophyll total value, nitrogen content, leaf surface temperature, and leaf surface humidity, which can be displayed on the same screen and stored simultaneously

4.16GB large storage space, data can be grouped for storage, viewing, and exporting

5. Multi functional USB interface, which can realize data export and charging functions. The instrument can be directly connected to the computer, and data export does not require upper computer software. It can also choose to use a memory card to directly export data, with simple and convenient operation

6. Data browsing: can browse, transfer, and clear historical data on the instrument

7. GPS positioning function: It can display satellite positioning latitude and longitude in real time, and clarify the current detection location.

8. The instrument is equipped with a built-in 4G wireless transmission module (with two years of data flow as a gift), which supports real-time uploading of data in outdoor environments. The test results can be directly transmitted to a dedicated cloud agriculture data center, and an enterprise specific cloud agriculture data center account can be assigned to view the uploaded data.

9. The cloud agriculture data center can retrieve historical data according to any time period, view measurement time, chlorophyll a/b/total content, nitrogen content, leaf surface temperature, leaf surface humidity, GPS positioning information and other data, display the trend of each parameter process curve, view the maximum and minimum values, zoom in and out functions, support online download, EXCEL export, analysis, printing and other functions

10. High contrast LCD display screen, capable of displaying data clearly even under strong light

11. Low power mode design, built-in large capacity lithium-ion rechargeable battery, with overcharge prevention function, energy-saving and environmentally friendly, and convenient outdoor operation

12. Built in bilingual display in Chinese and English, one click switching, seamless integration
