【BJ-1B Soil Nutrient Rapid TesterProduct Features:

It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, and organic matter in soil, fertilizers, organic fertilizers, and plants, as well as soil acidity and alkalinity (qualitative and quantitative) and salt content. It can calculate the recommended fertilization amount for 70 national agricultural, fruit tree, and economic crop target yields.

Digitized circuits and programmed design minimize operator errors and labor intensity to the greatest extent possible.

The cassette part adopts a five channel, dual optical path, and serial structure design, with no mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results.

Using high brightness LED lights as the light source and silicon semiconductors as the signal receiving system, the lifespan can reach up to 100000 hours. The light source is stable and has good consistency.

Adopting LCD Chinese large screen display, Chinese menu prompts for operation, guiding the operation process.

Equipped with an embedded micro printer with printing function.

The power supply adopts a single hole independent socket, which can be connected to 220V AC power, car cigarette lighter power, solar power or other sources
