Hanna Instruments Boiler and Cooling Tower Photometer – HI83305

The HI83305 is a small multiparameter photometer designed for use in the lab or in the field for boiling and cooling tower applications. The meter is one of the most advanced available, with an innovative optical design that employs a reference detector and focusing lens to eliminate errors caused by changes in the light source as well as imperfections in the glass cuvette. This meter includes 30 different programmed methods for measuring 18 key water quality parameters, as well as an absorbance measurement mode for performance verification and users who want to develop their own concentration versus absorbance curves. Specific parameters for boiling and cooling towers include oxygen scavengers and silica, which are important for equipment maintenance.

With its digital pH/temperature electrode input, the HI83305 doubles as a professional pH meter, saving valuable laboratory benchtop space. Now, a single meter can perform both photometric and pH measurements.

  • A cutting-edge optical system
  • A benchtop photometer with unrivaled performance
  • Input from a digital pH electrode
  • Save valuable bench space by using a meter that functions as both a photometer and a laboratory pH meter.
