The AP300 sensor is the perfect starting point for pH or redox (ORP) measurements. Economical in outlay, yet powerful enough for the majority of standard applications, these PPS (Ryton) and PVDF-bodied sensors operate to 105 °C (221 °F) and 6 bar (90 psi). Backed by a gel-filled, no maintenance electrolyte, bulb and flat-glass versions ensure rugged performance and exceptional resistance to in-line coatings. With flexibility of mounting methods, the range provides uncomplicated, effective technology enabling on-site customization.
