Hach Company launched a series of 30 kinds of models of PCII a one-parameter water quality analyzer PCII series Pocket Colorimeter (measurable parameters and measuring ranges please refer to Table 2 PCII single-parameter water quality analyzer to measure the parameter list and the order number) applies not only to the Field of water quality tests, but also for water analysis in the laboratory. The series is pre-programmed Hach detection method in accordance with international standardization of the standard curve stored in single-parameter water quality analyzer, in a rigorous standardized laboratory calibration verification before delivery. This series of single-parameter water quality analyzer can measure one or more parameters, measurement results can be displayed directly. PCII single-parameter water quality analyzer uses an advanced optical system, expanding the colorimeter to measure the parameters of range, saving time required for sample dilution, making the analysis of efficiency is greatly improved. The main features of PCII single-parameter water quality analyzer as follows: ● Easy to carry: weighs only 230 grams; ● excellent waterproof performance: about 0.9 meters immersed in water up to 30 minutes still normal use; ● data logging function: Allows users store and recall 10 most recent data points to the need to manually record data; ● large-screen display: (1) with background lighting function, when the light is dim, easy reading on the viewing screen; (2) the battery indicator icon, you can indicate the battery level, to facilitate the timely replacement of the battery.
