Living chlorophyll meter

1. Application

The living chlorophyll meter can instantly measure the relative chlorophyll content (unit: SPAD) or greenness, nitrogen content, leaf surface humidity, and leaf surface temperature of plants, so as to understand the real nitro demand of plants and the lack of soil nitro or whether too much nitrogen fertilizer is applied. This instrument can be used to increase the utilization rate of nitrogen fertilizer and protect the environment. It can be widely used in agricultural and forestry-related scientific research units and universities to study plant physiological indicators and guide agricultural production.

2. Functional characteristics

1. Rapid and non-destructive plant living body detection. When measuring, you only need to insert the leaves. There is no need to pick the leaves. It does 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: ± 1.0 SPAD, repeatability: ±0.3 SPAD) ,, built-in anti-strong light interference system

3. All parameters can be measured at the same time in one operation. Chlorophyll, nitrogen content, leaf temperature, and leaf humidity are displayed on the same screen at the same time, and can be 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, and can directly connect the instrument to the computer. Data export does not require host computer software, and 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, which can clearly display data even under strong light

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

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

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