Fertilizer Tester

Instrument Features

• Can detect available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter and pH in chemical fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers, etc.) and plants, as well as various medium and trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon and molybdenum, and various heavy metal contents such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium and selenium.
• Android intelligent operating system, with more efficient and user-friendly operation; the instrument comes standard with WiFi network upload, 4G network transmission and GPRS wireless remote transmission for fast data upload.
• Built-in crop expert fertilization system, which can calculate and recommend the fertilization amount for the target yield of more than 100 kinds of national agriculture, fruit trees and cash crops, and scientifically guide agricultural production according to the fertilization formula.
• Adopts a precision rotating colorimetric cell design, making the light source consistency more precise and ensuring detection accuracy. It can rapidly detect 12 samples at a time, greatly improving detection efficiency and reducing detection cost.
• Built-in standard atlas for plant nutrition diagnosis; according to the pictures of nutrient deficiency of various crops, leaf comparison is carried out to diagnose abundance or deficiency.
• Adopts a self-developed patented analysis method using high-precision filter technology (patent number: ZL 2018 2 1777724.7); the cuvette slot uses a standard 1 cm cuvette, with no mechanical displacement or wear, and precise optical path test positioning, ensuring the detection results are better than the national standard requirements.
• The instrument is equipped with a data receiving platform; no data cable is needed, and data can be directly uploaded wirelessly via local area network and the Internet, facilitating data management and long-term data analysis.
• The instrument has a built-in new-generation high-speed thermal printer; after detection is completed, it can automatically print the detection report and QR code.
• High-sensitivity 7-inch capacitive touch screen with high-definition and highly interactive display, greatly reducing the cumbersome operations and errors of traditional instruments.
• Each channel is equipped with four-wavelength cold light sources, and all light sources achieve constant current and stable voltage to ensure wavelength stability. Silicon semiconductor is used as the signal receiving system, with a service life of up to 100,000 hours. Good reproducibility and high accuracy.
• High-strength PVC engineering plastic carrying case design, sturdy and durable, easy to carry; the power supply mode is AC/DC dual-use, and finished reagents are provided for field mobile testing.

Multiple Functions and Complete Test Items

Fertilizer nutrients: ● nitrogen, phosphorus and potassium in simple fertilizers; ● ammonium nitrogen, nitrate nitrogen, phosphorus, potassium and biuret in compound (mixed) fertilizers and urea; ● available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter and various humic acids in organic fertilizers (foliar fertilizers). The detection of trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon and molybdenum, as well as various heavy metals (lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium and selenium), can be expanded.

Technical Specifications

Test Speed

Testing one compound fertilizer sample (N, P, K) ≤ 50 minutes; each additional fertilizer sample adds 20 minutes. Testing one organic fertilizer sample (N, P, K, organic matter) ≤ 1.5 hours; each additional sample adds 30 minutes.

Test Error

The test result is a percentage content; the single-item error for fertilizers is ≤ 0.5%, and the error for the three items of nitrogen, phosphorus and potassium is ≤ 1%.

Product Features

• Full functions: the dedicated fertilizer nutrient detector has the most complete test items at home and abroad (all kinds of reagents can be purchased).
• Complete accessories: the instrument integrates reagents, utensils and instrument into one, convenient to carry, equivalent to a small laboratory; users only need to provide distilled water to complete all operations within the required time. It is suitable for agricultural service departments or agricultural material dealers to identify the authenticity of fertilizers, for fertilizer manufacturers to control fertilizer production, and for agricultural material quality inspection departments to crack down on counterfeit agricultural materials and regulate the agricultural material market.
• Reliable performance: the working stability is more than 10 times better than the national standard JJG 179-90 index, and the repeatability reaches the index level of a grating spectrophotometer.

After-Sales Service

The whole instrument has a one-year warranty, with lifetime free repair service, free mailing of the instrument, free provision of detection reagents and free training. Lifetime free technical support for agriculture such as soil and fertilizer is provided!
