AquaMetrix 500 series combination pH / ORP sensors use the conventional measurement technique employing a process pH glass electrode (platinum for ORP) which is compared to a reference electrode in KCl solution.

These combination probes provide an economical alternative to higher cost models. The durable materials wetted by the process provide excellent chemical resistance. The convertible design of these probes allows them to be used in flow-through and submersion applications thus minimizing inventory requirements. The probes are offered with or without temperature compensation.

AquaMetrix 500 series combination pH / ORP sensors can be directly connected to the Shark, SharkTX/P and 2200P/R analyzers, provided the instrument is within reach of the 10 foot sensor cable. For longer transmission distances, a preamplifier with automatic or fixed temperature compensation are available.
