Soil testing device

Testing items:
1. Soil nutrients:
● Ammonium nitrogen, available phosphorus, available potassium, moisture content, organic matter, pH (pH paper method), etc.;
2. Fertilizer Nutrients:
● Nitrogen, phosphorus, and potassium in single-component fertilizers;
● Ammonium nitrogen, phosphorus, and potassium in compound (mixed) fertilizers and urea;
● Available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, pH, organic matter, etc., in organic fertilizers.

• The “Integrated Aluminum Alloy Enclosure for Medication and Equipment” design combines medication, equipment, and instruments into one unit, making it convenient to carry and equivalent to a small laboratory. It is portable, durable, and comes with pre-packaged medication.

• Microcomputer-controlled with digital circuits and programmable design, featuring an LCD display and compatible with both AC and DC power. It is suitable for field testing, significantly reducing operator errors and labor intensity.

• Resolution of 0.001, touch-sensitive buttons, built-in thermal printer for printing test results.

• The colorimetric cell section features a single-channel, dual-optical path design with no mechanical displacement or wear, ensuring accurate optical path positioning and precise measurement results.

• Can detect available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil pH, and salinity (expanded) in soil, fertilizers, organic fertilizers, and plant tissues.

• It is easy to operate and fast, with ready-to-use reagents that require no preparation, making it suitable for agricultural service departments, agricultural input dealers, and fertilizer manufacturers for soil testing and fertilizer application, as well as for identifying the authenticity of fertilizers.

• It uses high-brightness LED lights as the light source and silicon semiconductors as the signal reception system, with a lifespan of up to 100,000 hours, ensuring stable and consistent light output.

• Reliable performance: operational stability exceeds the national standard JJG179-90 specifications by 6 times, with repeatability matching the performance of grating-type spectrophotometers.
