Most pH and ORP sensors share a common liability: the reference electrode.
Most pH and ORP sensors share a common liability: the reference electrode. Conventional designs rely on porous junctions that leak, contaminate, and drift, and that require frequent recalibration and replacement to stay accurate. The Badger Meter pH::lyser™ and redo::lyser™ eliminate that liability at the source with a technically unique non-porous, non-leaking combined reference electrode that delivers long-term stability without the maintenance burden.
Ion-Selective Measurement, Direct and Continuous
The pH::lyser uses ion-selective electrode (ISE) technology to continuously measure the concentration of dissolved hydrogen ions directly in the process stream, delivering real-time pH and temperature without reagents or manual sampling. The redo::lyser measures oxidation-reduction potential (ORP), quantifying the electron transfer activity of an aqueous solution to indicate oxidizing or reducing conditions. Both sensors are factory precalibrated and ship ready for immediate in-situ or flow-cell deployment with no field calibration required out of the box.
A built-in compressed-air cleaning system keeps the sensor surface free of fouling between measurement cycles, and plug-and-play compatibility with the s::can terminal ecosystem enables multi-parameter monitoring, remote data management, and seamless SCADA integration. Both sensors are part of the BlueEdge® suite of scalable water management solutions from Badger Meter.
