Handheld plant nutrient rapid analyzer YT-YD

1、 Purpose:

The plant nutrient analyzer can instantly measure the relative chlorophyll content (SPAD) or greenness level, nitrogen content, leaf moisture, and leaf temperature of plants, thereby understanding the true nitrate demand of plants and the degree of soil nitrate deficiency or whether excessive nitrogen fertilizer is applied. This instrument can increase the utilization rate of nitrogen fertilizer and protect the environment. It can be widely applied in agricultural and forestry related research institutions and universities to study plant physiological indicators and provide guidance for agricultural production.

2、 Functional Features

1. Fast and non-destructive plant live detection, measurement only requires inserting the leaves, no need to pick the leaves, does not affect the normal growth of crops, can monitor the leaves throughout the crop growth process, and 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. One operation can simultaneously measure all parameters, including chlorophyll, nitrogen content, leaf surface temperature, and leaf surface humidity, which can be displayed on the same screen and stored simultaneously

4.16GB large storage space, data can be grouped for storage, viewing, and exporting

5. Multi functional USB interface, which can realize data export and charging functions. The instrument can be directly connected to the computer, and data export does not require upper computer software. It can also choose to use a memory card to directly export data, with simple and convenient operation

6. Data browsing: Historical data can be browsed and abnormal data can be deleted on the instrument

7. High contrast LCD display screen, which can clearly display data even under strong light

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

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