Soil Organic Matter Analyzer

Soil Organic Matter Analyzer

  • Product Number:LD-YJA
  • Product Difference:Testing the organic matter content in soil, chemical fertilizers, organic fertilizers, and plants, as well as soil pH and salinity (extended)

Product Introduction

The following items can be tested:
1. Soil: organic matter, acidity/alkalinity (pH paper method), etc.
2. Fertilizers: organic matter in single-component fertilizers, organic matter in compound (mixed) fertilizers and urea, and organic matter in organic fertilizers.
3. Plants: organic matter in plants.

Product Features

  • Patented design of the “Aluminum Alloy Enclosure with Integrated Reagent Container,” featuring portability, durability, and compatibility with pre-packaged reagents.

  • Capable of measuring organic matter content in soil, fertilizers, organic fertilizers, and plant tissues, as well as soil pH and salinity (expanded functionality).

  • Microcomputer-controlled, digital circuitry, programmable design, LCD display, compatible with both AC and DC power, suitable for field testing, minimizing operator errors and reducing labor intensity.

  • Utilizes 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. Stable light source with excellent consistency.

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

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