Overview
The YN-AB chlorophyll detector is based on the theory of optical diffuse reflection and designed with a three wavelength solid-state light source photoelectric detection module. It adopts light source modulation, high pass filtering technology, and multiple impurity removal light interference technology, and the measured values are not affected by leaf thickness and color depth, achieving direct reading of plant chlorophyll A and B content. Testeable items: chlorophyll A and B values, total chlorophyll A and B content, chlorophyll A and B ratio.
Product Details
One measurement item
It can detect the content of chlorophyll A and B in representative leaves of crops, characterize the level of chlorophyll A and B content in the tested crop leaves, and serve as a reference indicator for crop nitrogen nutrition management.
Two main technical indicators
1. Number of working wavelengths: single channel, 3 optical paths, 2 working wavelengths, 1 reference wavelength.
2. Test item: Chlorophyll content.
Stability relative standard deviation ≤ 1%, repeatability relative standard deviation ≤ 3% (tested with 75% extinction film).
4. Power supply: The host is equipped with a rechargeable battery.
5. Power consumption: 300mw.
⒍ Chlorophyll content: At the end of the measurement, the average relative deviation RDA and standard deviation STD of the absorbance values of the two working wavelengths of the leaves in this group are automatically calculated; The CA and CB of each group of leaves, the total amount of chlorophyll A and B CA+CB, and the ratio of chlorophyll A and B CA/CB.
7. Data storage: It can store thousands of test data records for two models, and automatically overwrite them after recording.
⒏ It has functions such as fault self prompt, whiteboard cleanliness prompt, and low battery reminder.
Three external dimensions and weight
1. External dimensions
The external dimensions of the host are 205 × 75 × 30mm.
2. Weight
The weight of the host is 0.25kg.
