Soil organic matter content detector

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, greatly reducing operator errors and labor intensity.

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

★ Can detect the organic matter content, soil pH, and salt content (expansion) in soil, 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.

11. Testing speed: Measure the organic matter of a soil sample for ≤ 60 minutes (including pre-treatment time)

12. Can simultaneously detect 8 soil samples for ≤ hours (including pre-treatment time)

13. Data printing: Built in * * one click thermal printer (domestic * * patented design)

Test speed:

The soil organic matter content detector can simultaneously detect 8 samples;

Measure the organic matter of one soil sample for ≤ 60 minutes, and simultaneously test the organic matter of three soil samples for ≤ 80 minutes.

Instrument features:

Complete supporting facilities: The soil organic matter content detector integrates medicine, equipment, and instrument, making it easy to carry and equivalent to a small laboratory. Suitable for agricultural service departments, agricultural material distributors, and fertilizer manufacturers to test soil fertilization and distinguish the authenticity of fertilizers.

Easy to operate and fast, the finished drug is ready to use upon opening without the need for configuration.

Performance reliability: The working stability is 6 times better than the national standard JJG179-90 index, and the repeatability reaches the level of the grating spectrophotometer index.
