Formula fertilization by soil testing instrument

Model: NK-210. 15265616398 Yu Yang

One, introduction to instrument: NK-210 type of formula fertilization by soil testing instrument can detect the soil, fertilizer, plant available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, soil pH and soil salinity ( Quantitative ), in addition to having memory, print function, instrument also the memory of more than 80 kinds of crop growth nutrients required fertilization software system, according to user needs can be output guide fertilization amount and print out. Greatly easing the farmers throughout the country friends of formula fertilization by soil testing needs, but also for fertilizer production enterprises realize professional, systematic, information-based, the data provide a reliable basis for the agricultural sector, is the preferred formula fertilization by soil testing instrument. Widely applicable to: all levels of agricultural testing center, School of agricultural scientific research, fertilizer production, agricultural management, agricultural services, planting base field.

Two, features: 1, can be detected in soil, plant, chemical fertilizer, biological fertilizer in the samples of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter content, chloride ion content, soil pH and soil salt content.

2, spray steel shell, sturdy and beautiful, durable, equipped with " intelligent fertilization expert software " CD 3, containing a battery, indoor field type. A time display function, may realize the automatic detection of the sample time recording and preservation.

4, store 1000 sets of test data ( time, location, the samples of various nutrient results ) and other related information is stored, the data can be readily transfer view. 5, can print out the test date, number of samples, sample test items, contents, crop varieties, chemical fertilizers, fertilizer quantity and other related information, rich and detailed.

6, apparatus also memory 80 kinds of crop growth nutrients required for fertilization formula software, according to user needs can be output guide fertilization amount and print out. 7, using liquid crystal Chinese large-screen backlit display, Chinese menu operation, operation process. In 8, the testing with look back function, thus make products more convenient and rational. Three: 1, technical parameters, nutrient measurement technical parameters: ( 1): A value stability ( absorbance ) within three minutes of the drift of less than 0.001 ( 2): A value reproducibility ( absorbance ) is less than 0.003 ( 3): linear error is less than 1%

( 4) sensitivity: red≥ 4.5 × 10-5; blue≥ 3.17 × 10-3 ( 5): red wavelength range of 620± 4nm 440± 4nm; blue; green 520 ± 4nm, can scale full wavelength

( 6) source: using the latest imported TTP long-life light source ( 7) earthquake: qualified ( Note: the technical parameters were higher than the national standard ), pH ( pH 2 ) measurement of technical parameters: ( 1 ) the test range: 1 ~ 14 ( 2) error:± 0.13, salt ( conductance ) measurement of technical parameters: ( 1) the test range: 0.01% ~ 1% ( 2±5% ) relative error: 4, the apparatus used in power: ( 1): 180V ~ 240V AC, 50 Hz ( 2) DC : 18V, 5W ( the instrument cabin ).
