The ABB pH & ORP Sensor is an analogue pH sensor that is compatible with most ABB Analysers that have an analogue input.
For more than 20 years our OEM replacement sensors have provided our customers with superior performance over the original product in virtually every aspect. The chemical and physical resistance provides a superior service life of up to 10 times that of the OEM product. In nearly all cases our customers report less drift and significantly less maintenance and the reason they keep using Turtle Tough… a significantly lower cost of ownership.
The high capacity solid state Polypropylene reference junction provides superior chemical resistance to sulphides and other dissolved gasses. The standard sensor utilises a double junction, however, a triple junction is available as a special order. The sensor is built with PT1000 integrated temperature compensation element so that it interfaces seamlessly with the ABB Analysers, though a PT100 option is available.
For extreme applications that require our extreme slurry/abrasion resistant, zinc resistant or High HF resistant glass and a different analyser will need to be considered.
The challenge A major zinc producer informed us that during operation of the zinc concentrator and thickener, their pH sensors were unable to cope with the solids content and composition, causing the reference junction to persistently clog and foul.
