FK-CT20 Scientific soil nutrient detector
1. Operating system: Android operating system, the main control must use multi-core processor, CPU frequency ≥ 1.8GHz, large capacity memory, fast operation speed, strong stability, no stuck phenomenon. With USB dual interface, the upload data can be exported quickly.
2. The instrument adopts 7.0-inch large screen Chinese character backlight display, can store and print test results, and has the function of historical data query and printing.
3. There is no need to make blank and standard samples for testing. Compared with other instruments, the operation steps, operation time and reagent consumption are reduced by half. The samples are read directly to eliminate the errors caused by traditional blank standard samples and ensure the accuracy of test results.
4. 12 channel rotary colorimetric cell (non solid module), which can detect 12 samples at the same time. Each sample can select different detection items, and rotate automatically. It has the function of reminding each channel to complete the detection.
5. The instrument has its own protection function, which can set user name and password; Equipped with fingerprint lock for fingerprint login, prevent non staff operation to view the experimental data.
6. Built in crop Atlas: according to the pictures of nutrient deficiency of each crop, compare the leaf surface, and diagnose the abundance and deficiency.
7. Data printing: the built-in thermal printer can print out the detection items, detection units, detection personnel, detection time, channel number, absorbance, content (mg / kg), two-dimensional code and other information.
8. Built in advanced locator to achieve accurate positioning of each channel;;
9. The instrument is equipped with four kinds of wavelength light sources (red, blue, green and orange). The wavelength of the light source is stable, the service life is up to 100000 hours, the reproducibility is good, and the accuracy is high.
10. the instrument is equipped with voltage display lamp, which displays the current voltage value in real time to ensure the stable voltage state of the operation process, and has the function of power off protection. In case of sudden power failure, the data can be stored automatically to prevent data loss
11. Simultaneous extraction and determination of fast available N, P, K and other nutrients in soil.
12. Detection speed: under normal proficiency level, it takes about 20 minutes to detect soil ammonium nitrogen, phosphorus and potassium (including soil sample pretreatment and chemical preparation), about 50 minutes to detect fertilizer nitrogen, phosphorus and potassium, and about 20 minutes to detect single trace element.
1. Power supply: AC 220 ± 22V DC 12V + 5V (large capacity lithium battery inside the instrument)
2. Power: ≤ 5W
3. Range and resolution: 0.001-9999
4. Repeatability error: ≤ 0.04% (0.0004, potassium dichromate solution)
5. Instrument stability: drift less than 0.3% (0.003, transmittance measurement) in one hour. After the instrument is started and preheated for 5 minutes, the display number will not drift within 30 minutes (light transmittance measurement); Within one hour, the digital drift shall not exceed 0.3% (transmittance measurement) and 0.001 (absorbance measurement); 5% (0. 005, transmittance measurement) within two hours.
6. Linear error: ≤ 0.2% (0.002, copper sulfate detection)
