Soil testing formula fertilizer applicator

(New development, agricultural material distributors, popularization of agricultural technology system)

(! Good compatibility, built-in lithium battery, printer, and all accessories used for testing, ensuring that users only need to provide pure water to accurately determine the pH and salt content of nitrogen, phosphorus, and potassium organic matter!)

Soil testing formula fertilizer applicator model: HM-TYA

Features:

1. The design of the integrated aluminum alloy case for chassis/medicine is easy to carry, sturdy and durable, and comes with finished medicine.

2. Microcomputer control, digital circuits, programmatic design, LCD display, dual use of AC and DC, capable of field flow testing, greatly reducing operator errors and labor intensity.

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

4. It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, and organic matter in soil, chemical fertilizers, organic fertilizers, and plants, as well as soil pH and salt content (extended).

5. The soil nutrient analyzer uses 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 consistent.

6. 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.

Test items:

Soil nutrients: ● Ammonium nitrogen, available phosphorus, available potassium, moisture, organic matter, pH test paper method, etc;

Test speed:

The soil testing formula fertilizer applicator can simultaneously detect 8 samples;

Test one soil sample (N, P, K) for ≤ 30 minutes, and simultaneously test three soil samples (N, P, K) for ≤ 40 minutes.

Features:

Complete supporting facilities: The soil testing formula fertilization 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.
