Plant Nitrogen content detector leaf nutrition Chlorophyll apparatus
Product description
The plant nutrient analyzer can instantly measure the relative chlorophyll content (unit SPAD) or green
degree, nitrogen content, leaf surface humidity and leaf temperature of plants, so as to understand the real
nitro demand of plants and understand the degree of lack of nitro in the soil or whether it is Too much
nitrogen fertilizer was 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 the guidance of agricultural production in agricultural and forestry-related research institutes and
universities.
Features
1. Fast and non-destructive plant living detection, only need to insert the leaves when measuring, no need to
pick leaves, does not affect the normal growth of crops, and can monitor the leaves during the whole process
of crop growth, so as to obtain more scientific analysis results
2. High measurement accuracy (accuracy: ± 1.0 SPAD, repeatability: ± 0.3 SPAD), built-in anti-glare
interference system
3. All parameters can be measured at the same time in one operation, the four parameters of chlorophyll,
nitrogen content, leaf surface temperature and leaf surface humidity can be 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-functional USB interface, which can realize data export and charging functions, and can directlyconnect the instrument to the computer. Data export does not require host computer software. You can also
choose to use a memory card to directly export data, and the operation is simple and convenient.
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 for outdoor operation
9. Built-in Chinese and English bilingual display, one-key switching, seamless docking
10. Standard configuration: host, charger, USB data cable, memory card, card reader, portable aluminum
case, certificate of conformity, manual, etc.
