Soil nutrient tester

Features:

★ The patented design of the “Integrated Aluminum Alloy Case/Pharmacy” is easy to carry, sturdy and durable, and comes with finished pharmaceuticals.

★ Micro computer control, digital circuit, programmatic design, LCD display, dual use of AC and DC, capable of field flow testing, reducing operator errors and labor intensity.

★ Resolution: 0.001, touch button, built-in * * thermal printer, can print test results.

★ It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, soil pH, salt content (expansion), as well as various trace elements such as calcium, magnesium, sulfur, boron, chlorine, and silicon in soil, chemical fertilizers, organic fertilizers, and plants.

★ 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 consistent.

The color comparison groove adopts a single channel and dual optical path design, with no mechanical displacement or wear. The optical path testing positioning ensures the accuracy of the measurement results.
