    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
