YSI ProSwap Digital Water Quality Meter
The ProSwap is a highly adaptable digital water quality meter designed to give users maximum flexibility in the field. With interchangeable smart sensors, built-in temperature measurement, and optional depth sensing, the ProSwap can be configured for a wide variety of applications — from turbidity and optical dissolved oxygen monitoring to spot pH sampling, conductivity profiling, and harmful algal bloom detection.
Its modular design makes it an ideal solution for professionals who need a portable, reliable, and cost-effective handheld meter that can adapt to changing monitoring requirements.
Flexible ProDIGITAL Platform
The ProSwap is built on the ProDIGITAL platform, allowing users to connect any ProDIGITAL integrated probe and cable assembly directly to the handheld. It is also compatible with ProDSS digital water quality sensors when used with a ProSwap cable.
Sensors and cable assemblies are fully user-replaceable and available in lengths from 1 to 100 metres, offering excellent flexibility across a range of sampling environments.
Smart Sensor Technology
ProSwap features advanced smart sensor technology that automatically recognises connected sensors and stores calibration data directly within each probe. This allows sensors to be swapped between handhelds without the need for recalibration, reducing downtime and improving workflow efficiency.
Built for Demanding Fieldwork
Designed for tough field conditions, the ProSwap features a rugged IP-67 waterproof housing and military-spec cable connectors for long-term durability. The handheld has been rigorously drop-tested and is backed by a 3-year warranty, with a 2-year warranty on cable assemblies and sensors.
Advanced Data Management
The ProSwap includes KorDSS Software for simple two-way communication between the handheld and a PC, making data transfer and management straightforward. For added convenience, data can also be exported directly to the included USB flash drive in CSV format without connecting to a computer.
