Chlorophyll detector (YT-YA)

Purpose

The chlorophyll analyzer uses two different light emitting tubes to irradiate leaves based on the absorption law of chlorophyll spectrum. By measuring the intensity of light passing through the leaves, the relative content or greenness of chlorophyll in the leaves is calculated, providing reliable scientific basis for reasonable, appropriate, and timely fertilization. It is widely used in scientific research and production guidance in agriculture, forestry, plants, and other fields.

Functional characteristics

1. Rapid non-destructive plant live detection, which only requires inserting the leaves during measurement, without the need to pick the leaves, and does not affect the normal growth of crops. The leaves can be monitored throughout the entire process of crop growth, thereby obtaining more scientific analysis results

2. High measurement accuracy (accuracy: ± 1.0 SPAD, repeatability: ± 0.3 SPAD)

3.16GB of large storage space, data can be stored, viewed, and exported in groups

4. Multifunctional USB interface, which can achieve data export and charging functions. It can directly connect the instrument with the computer, and data export does not require upper computer software. It can also choose to use a memory card to directly export data, which is simple and convenient to operate

5. Data browsing: You can browse the measured data on the instrument at any time and delete abnormal data at will

6. High contrast LCD display screen, which can clearly display data under strong light

7. Low power consumption mode design, built-in large capacity lithium-ion rechargeable battery, with anti overcharging function, energy-saving and environmentally friendly, and convenient for outdoor operations

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

9. Standard configuration: host, charger, USB data cable, memory card, card reader, portable aluminum box, certificate of conformity, instruction manual, etc
