ProDSS Digital Smart Sensors compatible with the YSI ProSwap Logger and ProSwap-1 Handheld. The ProSwap accepts one smart sensor at a time (in addition to the built-in temperature and depth sensors on the Logger).

Note: Turbidity and Total Algae sensors require the Extended Guard Kit (626740, sold separately in YSI ProSwap Logger Accessories). CT, DO, pH, and ISE sensors use the standard Short Guard Kit included with the logger.
