ENVIRONMENTAL SAMPLING EQUIPMENT
The YSI ProSwap Logger is a slim, single-port submersible monitoring sonde with built-in temperature and depth sensors — ideal for continuous, unattended deployments in groundwater wells, deployment pipes, streams, and shallow spaces. The internal Li-ion battery version delivers at least 90 days of autonomous logging at a 15-minute interval with no external power needed, making it the right choice for remote sites.
Add any single ProDSS Digital Smart Sensor (sold separately) to measure a second parameter alongside built-in temperature and depth. Compatible sensors include conductivity/temperature, optical DO, pH, pH/ORP, turbidity, algae, ammonium, nitrate, and chloride.
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.
