ProSwap Digital Water Quality Meter

Swap one smart sensor for another with the ProSwap digital water quality meter. Featuring built-in temperature and optional depth sensors, ProSwap can transform into whatever you need it to be: a purpose-built turbidity meter or a high-accuracy optical DO meter; a spot sampling pH meter or a profiling conductivity-temperature-depth system. It can even handle beach monitoring for harmful algal blooms.

Swap one sensor for another! The ProSwap incorporates smart sensor technology that enables sensors to be automatically recognized by the handheld. Additionally, DIGITAL sensors store calibration data, so probe assemblies can be swapped between handhelds without the need for re-calibration.
