Plant Nutrition Tester

1. Application

The plant nutrition meter can instantly and non-destructively 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 the research of plant physiological indicators and guidance of agricultural production in agricultural and forestry-related scientific research units and universities.

2. Technical indicators

3. Features

1. Rapid and non-destructive plant 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 crop growth process 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 simultaneously in one operation. Chlorophyll, nitrogen content, leaf surface temperature, and leaf surface 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 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, transfer, and clear historical data on the instrument

7. GPS positioning function: It can display the satellite positioning longitude and latitude in real time to clarify the current detection location. 8. The instrument has a built-in 4G wireless transmission module, which supports real-time data upload in the field environment. The test results can be directly transmitted to the exclusive cloud agriculture data center, and the company's exclusive cloud agriculture data center account is allocated. The account center can view the uploaded data of different testers.

9. The cloud agriculture data center can retrieve historical data according to any time period, and can view data such as measurement time, chlorophyll content, nitrogen content, leaf temperature, leaf humidity, GPS positioning information, etc., display the process curve trend of each parameter, maximum and minimum display, zoom in and out functions, support online download, EXCEL export, analysis, and printing

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

11. 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

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

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