Analytical Technology (ATi) has introduced the innovative new C10/77 Particle Sensor, for the continuous on-line monitoring of particle counts in raw water, filter influent and filter effluent. Based on a laser light blocking principle, this novel sensor can provide particle count data over size ranges from two to 200 microns, with three 4-20 mA analogue outputs and an RS-232/485 digital output supplied as standard. ATi currently has over 75 of these monitors working in various water companies in the UK.

Turbidity monitoring of filtered potable water provides an excellent indicator of water clarity as well as a reliable measure of general filter efficacy.

Recent studies, however, indicate that particle count data can provide additional information concerning filter operation, and often can provide an early warning of filter breakthrough before turbidity values begin to rise.

Each C10/77 Particle Sensor from ATi contains an integral LED display used to indicate either raw count data or differential counts.

The user may select a display of the total particles about a certain size, or differential counts.

The display is operated from sealed membrane switches on the front unit.
