Chlorophyll meter (YT-YC)

 Purpose

The plant nutrient analyzer can instantly measure the relative chlorophyll content (in units of SPAD) or greenness, nitrogen content, and leaf surface temperature of plants, thereby understanding the true nitro demand of plants and understanding the degree of soil nitro deficiency or whether nitrogen fertilizer has been applied excessively. This instrument can 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.

 Functional characteristics

1. Rapid non-destructive plant live detection, which only requires inserting the leaves during measurement, without the need to pick the leaves, and does not affect the normal growth of crops. The leaves can be monitored throughout the entire process of crop growth, thereby obtaining 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, and leaf surface temperature, which can be displayed on the same screen and stored simultaneously

4.16GB of large storage space, data can be grouped, stored, viewed, and exported

5. Multifunctional USB interface, which can achieve data export and charging functions. It can directly connect the instrument with the computer, and data export does not require upper computer software. It 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 screen, which can clearly display data under strong light conditions

8. Low power consumption mode design, built-in large capacity lithium-ion rechargeable battery, with anti overcharging function, energy-saving and environmentally friendly, and convenient for outdoor operations

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

10. Standard configuration: host, charger, USB data cable, memory card, card reader, portable aluminum box, certificate of conformity, instruction manual, etc
