I. Product Overview

Based on the spectral absorption characteristics of chlorophyll, the HD-YLB chlorophyll meter illuminates the leaf with two different light-emitting diodes and calculates the relative chlorophyll content, or greenness, of the leaf by measuring the intensity of the light transmitted through it. It therefore provides a reliable scientific basis for rational, appropriate and timely fertilisation, and is widely used in scientific research and production guidance in agriculture, forestry and plant science.

II. Key Features

1. Fast, non-destructive measurement of living plants: the leaf is simply inserted into the measuring head, without detaching it, so normal crop growth is not affected and the leaf can be monitored throughout the whole growth period for more scientific analysis results.

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

3. All parameters are measured in a single operation: chlorophyll and leaf surface temperature are displayed on the same screen at the same time and stored simultaneously.

4. 16 GB of storage; data can be stored, viewed and exported by group.

5. Multi-function USB interface for both data export and charging; the instrument can be connected directly to a computer, and data export requires no host software. Data can also be exported directly to a memory card, which makes operation simple and convenient.

6. Data browsing: historical data can be viewed on the instrument and abnormal data deleted.

7. High-contrast LCD display, clearly readable even in strong light.

8. Low-power design with a built-in large-capacity lithium-ion rechargeable battery and overcharge protection — energy-saving, environmentally friendly and convenient for field work.

9. Built-in bilingual Chinese/English display with one-key switching.
