Fertilizer nutrient 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, reducing operator errors and labor intensity.

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

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

★ 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.

★ Adopting independent patented analysis methods to ensure that the detection results absolutely meet the requirements of national standards.

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

Product instrument features:

The fertilizer nutrient dedicated rapid detection instrument is fully equipped: this instrument 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.
