The Plant Nutrient Analyzer instantly measures a plant's relative chlorophyll content (in SPAD units) or greenness level, nitrogen content, and leaf surface temperature. This enables accurate assessment of the plant's actual nitrate requirements and reveals the degree of soil nitrate deficiency or excessive nitrogen fertilizer application. Utilizing this instrument enhances nitrogen fertilizer utilization efficiency while protecting the environment. It finds extensive application in agricultural and forestry research institutions and universities for studying plant physiological indicators and guiding agricultural production.
Rapid, non-destructive live plant detection. Simply insert leaves during measurement—no need to pick leaves, ensuring no impact on normal crop growth. Monitor leaves throughout the entire growth cycle for more scientific analysis results.
Multi-functional USB port enables data export and charging. Directly connect the device to a computer for data export without requiring host software. Alternatively, export data directly via memory card for simple and convenient operation.
16GB large storage capacity allows grouping, viewing, and exporting of data.
Data browsing: Historical data can be viewed and abnormal data deleted directly on the instrument.
Built-in bilingual (Chinese/English) display with one-touch switching for seamless operation.
High-contrast LCD display ensures clear visibility even in bright sunlight.
Low-power mode design with built-in high-capacity rechargeable lithium-ion battery featuring overcharge protection, energy-efficient and environmentally friendly for convenient outdoor operation.
High measurement accuracy (Accuracy: ±1.0 SPAD, Repeatability: ±0.3 SPAD) with built-in anti-glare interference system.
