Aquascan - Introduction Aquascan is an online instrument capable of simultaneous multi-parameter measurement for a full range of water quality parameters. Developed by Hyder Consultancy in the early 1990’s. In 1996 Siemens purchase manufacturing rights and undertake further development of product.
Common Problems Reported by Users of conventional on - line analysers Sampling - Sample lines, Internal tubing Filtration - Lost sample, maintenance Reagents- Cost and H & S Risk Sample Size- Sample often l volumes
Customer Feedback Ideal Continuous Monitor Trend Monitor for Early Warning No sample Pre-treatment Rapid Response Reagent Free Low Maintenance Low Cost of Ownership
Direct measurements :- pH Sample Temperature (deg C) Conductivity (uS) UV254 Absorption UV313 Absorption UV405 Absorption Infra Red Absorption Infra Red scatter Ion Selective Electrode (Ammonium)
