Leaf Chlorophyll Meters

1. Use of Leaf Chlorophyll Meters

Leaf Chlorophyll Meters are used to calculate the relative content of chlorophyll in leaves, and can measure the chlorophyll concentration in leaves without damaging crops.Leaf Chlorophyll Meters uses two different light-emitting tubes to illuminate leaves according to the chlorophyll spectrum absorption law. By measuring the intensity of light passing through the leaves, the relative chlorophyll content or green degree in the leaves is calculated, thereby providing a reliable scientific basis for reasonable, appropriate and timely fertilization. It is widely used in scientific research and production guidance in agriculture, forestry, plants, etc.

2. Leaf Chlorophyll Meters Features

1. Rapid and non-destructive plant live detection. When measuring, you only need to insert the leaves. There is no need to pick the leaves, which will not affect the normal growth of crops. The leaves can be monitored throughout the growth process of crops, so as to obtain more scientific analysis results.

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

3. All parameters can be measured at the same time in one operation. Chlorophyll and leaf surface temperature can be displayed on the same screen and stored at the same time.

4.16GB large storage space, data can be stored, viewed and exported in groups

5. Multi-function USB interface, which can realize data export and charging functions, can directly connect the instrument to the computer, and data export does not require host computer software. You can also choose to use a memory card to directly export data, which is simple and convenient to operate.

6. Data browsing: You can browse historical data and delete abnormal data on the instrument

7. High contrast LCD display, data can be clearly displayed even under strong light

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

9. Built-in Chinese and English bilingual display, one-click switching, seamless docking.

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