HI83308 is a compact, multiparameter photometer for use in water conditioning applications. The meter is one of the most advanced photometers available with a innovative optical design that utilizes a reference detector and focusing lens to eliminate errors from changes in the light source and from imperfections in the glass cuvette. This meter has 23 different programmed methods measuring 15 key water quality parameters and also offers an absorbance measurement mode for performance verification and for users that would like to develop their own concentration versus absorbance curves. Water conditioning parameters include fluoride, chlorine, ammonia, manganese, copper, iron, silver and zinc.
