Online Chlorine Residual Analyzers Maintenance Benchmarking Practices

The Instrumentation Testing Association (ITA) conducted an instrumentation, control & automation maintenance benchmarking survey in Spring 1999. This paper presents comprehensive maintenance information and benchmarking data of various, total and free, online chlorine residual analyzer technologies. The paper includes chlorine residual analyzer maintenance benchmarking data reported by 135 water, wastewater, and industrial treatment facilities. The paper provides an analysis of analyzer applications; manufacturer and model in use; units and years in service; installation, calibration and maintenance practices; analyzer performance and accuracy; maintenance costs; and overall treatment facility profiles.
