CounterSense - Particle Counter


The Particle Counter range from Pi gives you a world’s first. The first to allow multiple sensors on a single analyser. The CounterSense is a sophisticated online particle counter with the capability to size and count particles from 2 to 100 microns and to count form 2-750 microns. The FilterSense has the capability to size and count particles from 2-100 microns, and the ParticleSense is a standalone counter with the capability of counting and sizing particles from 2-125 microns.


The range of sensors are available with different controllers giving you the same great performance with different communication, display, and control options. With the Pi range of controllers, you get everything that you need – and nothing that you don’t, without sacrificing the quality of measurement. Each sensor comes with a ‘clean me’ alert and can be run with a constant head weir or a flow meter, to maintain a constant flow.
