1、 Product Introduction
Soil nutrients: nine items including ammonium nitrogen, nitrate nitrogen, available phosphorus, available potassium, organic matter, total nitrogen, pH value, moisture, and alkali hydrolyzed nitrogen; ▲ Trace elements: calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, etc.1. The colorimetric groove adopts a single channel and dual optical path design, with no mechanical displacement or wear. The optical path testing positioning is accurate, ensuring the accuracy of the measurement results.
2. Microcomputer control, digital circuit, programmed design, dual-use of AC and DC, capable of field flow testing, greatly reducing operator errors and labor intensity.
3. Chinese LCD display, easy and intuitive to operate and read data.
4. Resolution: 0.001, touch sensitive buttons, built-in thermal printer, capable of printing test results.
5. Using high brightness LED lights as the light source and silicon semiconductors as the signal receiving system. The light source is stable and has good consistency. It has the advantages of low power consumption, high reliability, and fast response speed.
6. The design of the integrated aluminum alloy chassis/medicine is easy to carry, sturdy and durable, and comes with finished medicine products.
7. Built in one click thermal printer, directly printing test results.
1. Power supply: AC 220 ± 22V DC 7V-9V (instrument built-in lithium battery)
2. Power: ≤ 5W

10. Salt content (conductivity): (1) Test range: 0.01% to 1.00% (2) Relative error: ± 5% (extended)
11. Soil moisture technical parameters Water unit:% (g/100g); Moisture content testing range: 0-100%; Error less than 0.5%
12. Simultaneous extraction and determination of three nutrients, namely N, P, and K, in soil at once, and scientific guidance on fertilizer application rates (drafter of the industry standard for rapid testing by the Ministry of Agriculture of China)
13. Simultaneous, rapid, and accurate detection of nutrients such as nitrogen (N), phosphorus (P), and potassium (K) in fertilizers
14. Test speed: Test a soil sample (N, P, K) for ≤ 30 minutes (including pre-treatment time, no need for the user to provide any attachments)
