K-Patents' PR-23-W is is used in large scale production and in large pipelines for chemically-aggressive solutions and ultra-pure fine chemical processes. Its Saunders body (diaphragm) sensor is designed to measure refractive index and temperature.
The PR-23-W graphite cast iron sensor body has a PFA chemical-resistant lining, and a stainless steel cover. Wetted parts are Spinel or Sapphire (prism), PTFE (prism gasket), and PVDF or PTFE (Teflon). It can be mounted in a vertical or a horizontal pipe.
The PR-23-W features digital sensing technology that is not affected by suspended solids, bubbles or color changes. The PR-23-W's measurement range covers 0-100% by weight.
