Fertilizer nutrient detector (YT-HD)

Model: YT-HD

Features: ★ Upgraded version, spray coated steel plate shell design, sturdy and durable, equipped with a complete set of accessories and finished chemicals.

★ Micro computer control, digital circuit, programmatic design, LCD display, dual use of AC and DC, capable of field flow testing.

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

The fertilizer nutrient dedicated detector can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon and other trace elements, as well as heavy metals such as lead, chromium, cadmium, mercury, arsenic, etc. in fertilizers and organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.).

★ Adopting high brightness LED light source and dual dial filter processing technology, ensuring stable wavelength of the light source. Silicon semiconductor is used as the signal receiving system, with a lifespan of up to 100000 hours. Stable light source, good reproducibility, and high accuracy.

The color comparison groove adopts a single channel design, with no mechanical displacement or wear. The optical path testing positioning is accurate, ensuring the accuracy of the measurement results.

★ Adopting independent analysis method (No. ZL 2018 2 1777724.7) to ensure that the detection results absolutely meet the requirements of national standards.

★ Equipped with a built-in thermal printer, the fertilizer printing result is a percentage content, with a testing error of less than 0.5%.

Multi functional and complete testing items:

Fertilizer nutrients: ● Nitrogen, phosphorus, and potassium in elemental fertilizers; Ammonium nitrogen, nitrate nitrogen, phosphorus, potassium, and biuret in Hefei and urea; Organic fertilizer (foliar fertilizer) includes available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, and various humic acids. Scalable detection of trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, as well as various heavy metals (lead, chromium, cadmium, mercury, arsenic).

11. Testing speed: Test a fertilizer sample (N, P, K) for ≤ 50 minutes (including pre-treatment time, no attachments need to be provided by the user)

12. Simultaneously test 5 fertilizer samples for ≤ 2 hours (including pre-treatment time)

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

14. Reserve a 232 data interface that can be connected to a computer for data transmission.

Test speed:

Test a compound fertilizer sample (N, P, K) for ≤ 50 minutes; Add 20 minutes for each additional fertilizer sample.

Test an organic fertilizer sample (N, P, K, organic matter) for ≤ 1.5 hours; Add 30 minutes for each additional sample.

 Testing error:

Fertilizer single item error ≤ 0.5%, nitrogen, phosphorus, and potassium three item error ≤ 1%.

 Product instrument features:

The fertilizer nutrient dedicated testing instrument has complete functions: the testing items are the most comprehensive both domestically and internationally (all types of pesticides can be purchased).

The instrument is fully equipped and integrates medicine, equipment, and instrument, making it easy to carry. It is equivalent to a small laboratory, and users only need to provide distilled water to complete all operations within the required time. Suitable for agricultural service departments or agricultural material distributors to distinguish the authenticity of fertilizers, fertilizer manufacturers to control fertilizer production, and agricultural material quality inspection departments to crack down on agricultural material counterfeits, regulating the agricultural material market.

Performance reliability: The working stability is more than 10 times better than the national standard JJG179-90 index, and the repeatability reaches the level of the grating spectrophotometer index.

 After sales service:

The entire instrument is guaranteed for five years, with lifetime free maintenance services, free shipping of instruments, free provision of testing reagents, and free training.

Lifetime free agricultural related technical support such as soil and fertilizer!
