Details:
 The DR Series 800 multi-parameter water quality analyzer, especially for the field test design, the measurement process is simple, fast. This multi-parameter colorimeter with automatic wavelength selection and automatic wavelength calibration function to store a number of standard curve, number of measurable parameters, large-screen display of measurement results directly. Pink pillow, ampoules, pre-installed pipe (TNT tube) different packaging prefabricated reagent, can greatly shorten the time of sample analysis. The colorimeter can record 99 sets of data, the The can pass HachLinkTM software experimental data downloaded directly to your computer for easy data storage and management.
 
The DR Series 800 multi-parameter colorimeter available in three models: DR 890, DR 850, DR 820, respectively, to store 90, 50, 20 standard curve, various models given an dustproof, chemical resistant, waterproof function
