Functional features: 

1.the instrument is small and convenient. It can be operated with one hand.

2.It can simultaneously measure the chlorophyll content of plants. The two indexes of leaf temperature can be measured non destructively. 

3.It can quickly and non destructively detect plants in vivo. 

4.After the accidental power failure of harmful crop growth, the data in the host will not be saved and will not be lost. 

5..W historical data can be viewed, or deleted one by one or all with one key. 

6.Reasonable power management scheme, built-in rechargeable lithium battery, the instrument has its own backlight function, and the instrument has its own USB interface, which can be connected to the computer to export the measurement data, so as to facilitate the management and analysis of plant nutrients. 

7.You can input the plant name, standard nitrogen content and utilization rate to directly calculate the amount of fertilizer. 

8.With the function of uploading on the network platform, customers can view the data and curve chart through any computer with internet access or check it on the mobile terminal
