Boiler and Cooling Tower Photometer - HI83305

HI83305 is a compact, multiparameter photometer intended for boiling and cooling tower applications for use in the lab or in the field. The meter is one of the most advanced photometers available with an 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 30 different programmed methods measuring 18 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. Parameters specific to boiling and cooling towers include oxygen scavengers and silica which are important for maintaining equipment.

To save valuable laboratory benchtop space, the HI83305 doubles as a professional pH meter with its digital pH/temperature electrode input. Now one meter can be used for both photometric and pH measurements.
