Introduction : The instrument adopts the NH3-N reaction of Nessler's reagent and dissociative NH3 or Ammonium ion generates yellow-brown complex. The NH3-N concentration will be calculated by the single-chip computer and the optical colorimetry as the complex color depth is proportional with the concentration of NH3s-N. It’s widely used in the measurement of surface water, industrial waste water and sewage. Features: 1. V/F conversion, digital filter and other technology, excellent stability and anti-interference ability. 2. Adopt the national standard method; NH3-N content is displayed directly. 3. High efficiency and accuracy, the whole experiment only needs 10min. 4. Auto-save each parameter if power failure. 5. Single buttom and easy operation. Technical Parameter: 1. Measure Range: 0.02~10mg/L(can be diluted if exceeds 10mg/L) 2. Accuracy: <±3%(F.S) 3. Lowest Detectable Limit: 0.01mg/L 4. Repeatability: <±2% 5. Absorptance Drift ≤0.001A /10min 6. Dimension: 282mm×237mm×102mm 7. Weight: 2.2kg 8. Operating Condition: Operating Temperature Range: 5~40℃ Relative Humidity: ≤85% Power Supply: AC(220±22)V;(50±0.5)Hz No obvious vibration and electromagnetic interference, avoid direct sunlight.
