SL-TF24 multi-channel soil fertilizer nutrient rapid analyzer

Multi channel intelligent soil (fertilizer) nutrient rapid measurement instrument

Brand: Silan Origin: Zhengzhou

Model: SL-TF24

1、 Performance characteristics

1. The instrument is designed with a 24 channel multi optical path independent structure, ensuring precise positioning for optical path testing and guaranteeing the accuracy of measurement results;

2. Adopting a 7-inch color touch screen display, user-friendly interface, and Android open-source operating system;

3. Equipped with a built-in micro printer, the test results can be stored and printed on the machine. The stored and printed content should include: testing unit, testing date, testing time, testing items, sample content, crop variety, fertilizer variety, fertilizer quantity, and other relevant information;

4. Recommended fertilizer application rates can be calculated for the target yields of over 100 types of national agricultural, fruit tree, and economic crops. Crop varieties, crop yields, fertilizer varieties, and target yields can be set according to local conditions, and the fertilizer application amount can be automatically calculated;

5. Data transmission can be remotely transmitted to a computer through wired or wireless means for further processing of the data;

6. The instrument is versatile and can be connected to multiple sensors to measure parameters such as CO2, soil salinity, photosynthetically active radiation, and light intensity; (Optional)

7. Equipped with a built-in high-power lithium battery pack, it can be used for both AC and DC, and can achieve field flow testing. The instrument has a low voltage display and can work in standby mode after power failure to prevent data loss;

8. It has voice guidance and broadcasting functions, as well as video guidance for operation.

2、 Test project
