The Orion 9770BNWP Residual Chlorine Electrode allows total residual chlorine to be measured quickly and accurately. All forms of total residual chlorine are measured: free chlorine, hypochlorites, and chlorine bound to nitrogenous compounds. This electrode method is EPA approved for drinking water and wastewater (EPA No. 330.5).
The method permits rapid analyses to be done at the sampling site, eliminating erroneous low readings due to Cl2 loss. (Samples not measured immediately are subject to chlorine loss due to reaction with oxidizable species in the sample).
This electrode method requires the addition of two reagents to the sample before measurement. The electrode has a slope of about + 29 mV per decade increase in concentration.
Orion 9770BNWP Chlorine Solid State Combination Electrode.
Teamed with the introduction of the Orion Star Series, Thermo Scientific has also introduced the new WP- waterproof and secure electrode connectors, a revolutionary feature of the new Orion Star Series Meters. The BNWP connector provides a waterproof and secure connection when used with the new Orion Star Series meters. The BNWP connector is compatible with any standard BNC connector both on Orion meters and competitive meter models.
Waterproof BNC electrodes have 1 M cables.
Screw Cap connector requires separate cable.
