Beijing Jinzhengmao Multifunctional Soil Tester
Function Introduction
The country's exclusive "chassis/agent integrated aluminum alloy chassis" design is easy to carry, sturdy and durable.
It can detect available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, and total potassium organic matter content in soil and chemical fertilizers and organic fertilizer plants, qualitative and quantitative soil pH and salt content, and soil moisture content. It can also be used as an automatic monitoring equipment for soil moisture. use. The recommended fertilization amount can be calculated for the target yield of national agricultural fruit tree cash crops.
Digital circuit programming design minimizes operator errors and labor intensity.
The cassette part adopts a five-channel dual optical path series structure design, which has no mechanical displacement and wear. The optical path test positioning is accurate, ensuring the accuracy of the measurement results.
Using high-brightness lamps as the light source and silicon semiconductors as the signal receiving system, the lifespan is up to 10,000 hours. The light source is stable and consistent.
Using LCD Chinese large screen display, Chinese menu prompts operations and guides the operation process.
Equipped with an embedded micro printer with printing function.
The power supply adopts a built-in lithium battery pack and is equipped with an automatic charging circuit. The single-hole independent socket can be connected to AC car cigarette lighter power supply, solar power supply or other arbitrary current power supply.
