HM-FB organic fertilizer detection instrument Features: 1. The patented design of the "Integrated Aluminum Alloy Case/Drug Case" is easy to carry, sturdy and durable, equipped with testing methods and finished drugs. 2. Microcomputer control, digital circuit, programmatic design, LCD display, dual use of AC and DC, test data can be stored and queried, and can be tested in the field, reducing operator errors and labor intensity to a certain extent. 3. Resolution: 0.001, touch button, built-in new generation thermal printer, can print test results. 4. It can detect the content of available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, pH, various trace elements such as calcium, magnesium, sulfur, iron, manganese, boron, zinc, copper, chlorine, silicon, molybdenum, as well as heavy metals such as lead, chromium, cadmium, mercury, arsenic, nickel, aluminum, fluorine, titanium, selenium, etc. in fertilizers, organic fertilizers (including foliar fertilizers, water-soluble fertilizers, spray fertilizers), and biological fertilizers. 5. High brightness LED light source is used for filtering processing, 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. 6. The colorimetric 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. Technical parameters: 1. Power supply: AC 220 ± 22V DC 12V+5V (can be used as an onboard power supply or choose the instrument's built-in lithium battery) 2. Power: ≤ 5W 3. Range and resolution: 0.001-9999 4. Repeatability error: ≤ 0.3% (0.003, potassium dichromate solution) 5. Instrument stability: Within three minutes, the drift is less than 0.2% (0.002, transmittance measurement). After preheating the instrument for 5 minutes, it shows no digital drift within two minutes (transmittance measurement), and the digital drift does not exceed 0.3% within five minutes (transmittance measurement); Digital drift within 20 minutes shall not exceed 0.5% (transmittance measurement) and 0.001 (absorbance measurement); Digital drift within thirty minutes shall not exceed 0.7% (transmittance measurement) and 0.002 (absorbance measurement). 6. Linear error: ≤ 1% (0.01, copper sulfate detection) 7. Sensitivity: Red light ≥ 4.5 × 10-5 Blue light ≥ 3.17 × 10-3 Green light ≥ 2.35 × 10-3 Orange light ≥ 2.13 × 10-3 8. Wavelength range: Red light: 680 ± 2nm; Blue light: 420 ± 2nm; Green light: 510 ± 2nm; Orange light: 590 ± 4nm 9. Simultaneous, rapid, and accurate detection of nutrients such as nitrogen (N), phosphorus (P), potassium (K), and organic matter in fertilizers 10. Data printing: Built in new one click thermal printer (the first in China)
