Sample Filter

The Forbes Marshall Relisafe™ Series Sample Filters provide essential particulate protection for sensitive online water quality analysers. The Relisafe™ HPSF and Relisafe™ LPSF models are forged-body filters that utilise an ergonomic hex-cap design to rapidly remove suspended matter from sample flows without requiring specialised tools. These filters guarantee zero disruption to your localised instrumentation rack while eliminating sensor fouling.
