DPA / DPAS

Combine Accuracy and Ease of Use

The DPA/DPAS are pre-pressurized, gel-filled, low-maintenance pH or redox

sensors for in-line measurements of industrial processes. Pre-pressurized reference electrolyte prevents influx of process medium and keeps the reference junction

clean. The silver-ion trap prevents reference junction fouling even in solutions containing sulfide. The DPAS delivers fast and precise measurements, even after repeated autoclaving or sterilization cycles at 130 °C （266 °F）.

The DPA/DPAS sensors are also available as a platinum redox （ORP） sensor for oxidation-reduction measurements.
