Water
Quality Analyzer
The
WQA is a robust, portable, water diagnostic particle counter.
The WQA may be used as a point of use analyzer or lab
qualification instrument. The WQA 2000 provides 8-channel
tracking, in either differential or cumulative mode, for
particles as small as 2 mm. When sensitivity is critical, the
WQA 1000 provides 8-channel tracking for particles as small as
1mm. Sample and purge volumes are user selectable from 10 to
1000ml. All 8 channels are simultaneously viewable on a large,
easy to read LCD display.
