Chlorophyll Meter

Instrument name: Chlorophyll measuring instrument

Instrument model: HM-YA

Purpose

The chlorophyll meter 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 chlorophyll content or green degree inside the leaves can be 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 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 (accuracy: ± 1.0 SPAD, repeatability: ± 0.3 SPAD)

3.16GB large storage space, data can be grouped for storage, viewing, and exporting

4. 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

5. Data browsing: Measurement data can be browsed at any time on the instrument, and abnormal data can be deleted at will

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

7. 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

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

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