Hash DR820 multi-parameter water quality analyzer 
 The DR820 multi-parameter water quality analyzers, specifically designed for field testing, the measurement process is simple, fast. DR800 Series multi-parameter water quality analyzer with automatic wavelength selection and automatic wavelength correction function to store a number of standard curve to measure multiple parameters, large-screen direct display measurement results. Powder pillow, ampoules, pre-installed tube (TNT tube) different packaging prefabricated reagent, can greatly shorten the time of sample analysis. The instrument can record 99 sets of data, and through HachLinkTM? Software to experimental data downloaded directly to your computer for easy data storage and management.
