1=>Quickly test the N, P, K, organic matter, salinity, pH, and soil moisture in soil.
2=>Salinity sensor is a non-glass electrode solid-state sensor, which can be buried into soil for direct reading.
3=>Multiple channels: able to test 8 or 1 sample simultaneously.
4=>7-inch color touch screen, Android system, supporting online upgrade.
5=>With time display function, can automatically record and store testing time.
6=>Stores about 1,000 groups of data; data can be checked at any time.
7=>Equipped with a clock chip, displaying time in year, month, day, hour, and second.
8=>GPS function included.
9=>Built-in data logger: all test values are stored automatically without data loss.
10=>Able to print data including test date, sample No., test items, sample content, crop variety, etc.
11=>Able to set crop variety, crop yield, and fertilizer variety, and automatically calculate the fertilization amount.
12=>Data can be transmitted to a computer via Wi-Fi.
13=>According to local conditions, set crop variety, productivity, and fertilizer variety, then automatically calculate the fertilization amount.
14=>Built-in large-capacity rechargeable battery; both AC and DC power supplies are available.
15=>Able to connect other optional sensors such as air temperature and humidity sensors, soil temperature and moisture sensors, CO₂ sensors, PAR (Photosynthetically Active Radiation) sensors, light sensors, etc.
