Plant nutrient speedometer

1.Uses of Plant Nutrient Speedometer

Plant nutrient speedometer is a rapid and non-destructive measurement of leaf chlorophyll, nitrogen and leaf temperature and humidity by using near infrared spectroscopy technology.Plant nutrient speedometer 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 actual nitro demand of plants and the lack of soil nitro or whether too much nitrogen fertilizer has been 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. Plant nutrient speedometer features

1. Rapid and non-destructive plant live 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 growth process of crops, so as to obtain more scientific analysis results.

2. High measurement accuracy (accuracy: ± 1.0SPAD, repeatability: ±0.3SPAD), 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 can be displayed on the same screen and 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, can directly connect the instrument to the computer, and data export does not require host computer software. 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, data can be clearly displayed even under strong light

8. Low power consumption mode design, built-in large-capacity lithium-ion rechargeable battery, with anti-overcharge function, energy-saving and environmentally friendly, 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 box, certificate, instruction manual, etc.
