Introduction: The instrument uses Nessler colorimetric measurement of ammonia in the water, the method is simple and high sensitivity. The principle is: ammonia or ammonium ions exist in the free state and sodium's reagent to generates yellow-brown complex, the complex is proportional to the chromaticity and ammonia content. Features High-performance ultra-low power 16-bit microcontroller, standby time of the instrument is up to six months or more. LCD large-screen LCD, easy and intuitive operation. Compact equipment, easy to carry. Saved standard curve 20 and 199 measured values (with a time stamp with the year, month, day, hour, minute, second ammonia values, absorbance and transmittance values. ) Cold light, narrowband interference optical system, good optical stability. Data power protection. Host chassis with molded ABS material, IP65 design, good corrosion waterproof and dustproof performance. Technical Parameter Measuring range :0.02-25mg / L (range is divided into two: 0 ~ 5mg / L, 5 ~ 25mg / L can be measured over range after dilution.) Basic error: ± 3% (F.S) Repeatability: ≤ 3% Dimensions: 80mm × 230mm × 55mm Weight: 500g Normal conditions of use: Ambient temperature: 5 ~ 40 ℃ Relative humidity: ≤ 85% Power supply: 4 5 # batteries no significant vibration and electromagnetic interference, avoid direct sunlight.
