YSI ProSwap Logger — External Power (No Battery)

The no-battery version of the YSI ProSwap Logger — same slim, single-port submersible sonde with built-in temperature and depth sensors, but requires external power via the Topside Power Pack (6×AA batteries) or Flying Lead Adapter (connects to an existing DCP). Ideal for sites where AC or DCP power is already available, or where an extended power pack is preferred over a rechargeable internal battery. Add any single ProDSS Digital Smart Sensor (sold separately) to measure a second parameter alongside built-in temperature and depth. Note: Turbidity and Total Algae sensors require the Extended Guard Kit (626740, sold separately). CT, DO, pH, and ISE sensors use the standard Short Guard Kit included with the logger.
