Organic Fertilizer Detector

Characteristic:

★ The patented design of the integrated aluminum alloy chassis/medicine box is easy to carry, sturdy and durable, and comes with finished medicines.

★ Microcomputer control, digital circuit, programmed design, LCD display, dual-purpose AC/DC, capable of field flow testing, minimizing operator errors and labor intensity to the greatest extent possible.

★ Resolution: 0.001, touch sensitive buttons, built-in new thermal printer, capable of printing test results.

★ The fertilizer nutrient dedicated rapid detector can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, etc. in fertilizers and organic fertilizers.

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

The colorimetric groove adopts a single channel and dual optical path design, with no mechanical displacement or wear. The optical path testing positioning is precise, ensuring the accuracy of the measurement results.

★ Adopting independent invention patent analysis method to ensure that the test results absolutely meet the national standard requirements.

The fertilizer printing result shows a percentage content, with a testing error of less than 1%.

10. Can simultaneously detect 8 soil samples for ≤ 3 hours (including pre-treatment time)

11. Data printing: Built in new one click thermal printer

Test speed:

Test a fertilizer sample (N, P, K) for ≤ 1 hour; Simultaneously test three fertilizers (N, P, K) for ≤ 1.5 hours.

test error:

The individual error of fertilizer is ≤ 1.5%, and the total error of nitrogen, phosphorus, and potassium is ≤ 3%.

Instrument features:

Fully equipped: This instrument integrates medicine, equipment, and instruments, making it easy to carry and equivalent to a small laboratory.

Suitable for agricultural service departments or agricultural material distributors, fertilizer manufacturers to conduct soil testing and fertilization, and to identify the authenticity of fertilizers. Easy to operate and fast, the finished medicine can be used immediately after opening the bottle, without the need for configuration.

Reliable performance: 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.
