Soil nutrient speed tester
Scope of application:
Agriculture, forestry, animal husbandry and fishery
Soil fertilizer nutrient rapid tester (agricultural material distributor, agricultural technology system practical type)
1. "Chassis / Pharmaceutical Integrated Aluminum Case" design, easy to carry, sturdy and durable, supporting finished pharmaceuticals.
2. Microcomputer control, digital circuit, programmed design, liquid crystal display, AC and DC dual-use, can be field flow test, reduce operator errors and labor intensity.
3. Resolution: 0.001, touch button, built-in thermal printer, can print test results.
4, can detect soil and chemical fertilizer, organic fertilizer, plant available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, soil pH, salt content, and soil calcium, magnesium, sulfur, Boron, chlorine, silicon and other six trace elements.
5, using high-brightness LED lights as the light source, silicon semiconductor as the signal receiving system, the life of up to 100,000 hours level. The light source is stable and consistent.
6. The colorimetric tank adopts a single channel and dual optical path design, without mechanical displacement and wear. The optical path test is accurately positioned to ensure the accuracy of the measurement result.
I. Test items:
Soil nutrients: ● Ammonium nitrogen, available phosphorus, available potassium, water, organic matter, pH (pH test paper method), and various medium and trace elements such as calcium, magnesium, sulfur, boron, chlorine, and silicon (extended);
Fertilizer nutrients: ● nitrogen, phosphorus, and potassium in elemental fertilizers; ● ammonium nitrogen, phosphorus, and potassium in compound (mixed) fertilizer and urea; ● available nitrogen, available phosphorus, available potassium, total nitrogen, and total phosphorus in organic fertilizers , Total potassium, pH, organic matter, etc.
Technical parameters of the instrument:
1. Power supply: AC: 180V ~ 240V, 50Hz; DC: 12V + 5V (can be connected to vehicle power supply)
2. Range and resolution: 0.001-9999
3. Stability: less than 0.003 drift within three minutes
4. Linear error: ≤3% (0.03, copper sulfate detection)
5. Repeatability error: ≤0.5% (0.005, potassium dichromate solution)
6. Sensitivity: red light ≥4.5 × 10-5 blue light ≥3.17 × 10-3
7.Wavelength range: 620 ± 8nm red light 440 ± 8nm blue light
8. Technical parameters of soil moisture Moisture unit: ﹪ (g / 100g) Water content test range: 0-1000 Accuracy: ± 0.5 ﹪
9. Determination of available N, P, and K nutrients in the soil at one time and scientifically recommended fertilizer application amount
10. Simultaneous, fast and accurate detection of nitrogen (N), phosphorus (P), potassium (K) and other nutrients in fertilizers
11. Test speed: test a soil sample (N, P, K) ≤ 30 minutes (including pre-treatment time)
12. Simultaneous detection of 8 soil samples ≤ 1 hour (including pre-treatment time)
13. Data printing: built-in one-button thermal printer (domestic patent design)
Can detect 8 samples at the same time;
Measure one soil sample (N, P, K) ≤ 30 minutes, and simultaneously detect three soil samples (N, P, K) ≤ 40 minutes;
Test one fertilizer (N, P, K) ≤ 50 minutes, and simultaneously test three soil samples (N, P, K) ≤ 1.5 hours.
Complete equipment: The instrument integrates medicine, device, and instrument into one, which is easy to carry and is equivalent to a small laboratory. It is suitable for the agricultural service department or agricultural material distributors, fertilizer manufacturers to test soil fertilization and identify the authenticity of the fertilizer.
The operation is simple and fast, and the finished product can be used immediately after opening the bottle without configuration.
Reliable performance: The working stability is 6 times better than the national standard JJG179-90, and the repeatability reaches the level of the grating spectrophotometer.
V. After-sales service:
The whole instrument warranty is one year (mainframe warranty for five years), free lifetime maintenance service, free mailing instrument, free training.
Provide free agricultural related technical support for life!
