Chlorophyll meter

I. Product Overview

The HD-YLC plant nutrient meter instantly measures the relative chlorophyll content (SPAD value) or greenness, the nitrogen content and the leaf surface temperature of plants, so that the actual nitrate requirement of the plant and the degree of nitrate deficiency or excess nitrogen fertilisation in the soil can be understood. The instrument helps to raise the utilisation rate of nitrogen fertiliser and to protect the environment. It is widely used by agricultural and forestry research institutes and universities for the study of plant physiological indices and for the guidance of agricultural production.

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), with a built-in anti-strong-light interference system.

3. All parameters are measured in a single operation: chlorophyll, nitrogen content 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.
