YSI ProPlus Water Quality Meter

Multi-Parameter Water Quality Meter: YSI ProPlus

The YSI ProPlus handheld multi-parameter water quality meter improves on the highly successful YSI556 series of instruments. The readout is slim and easy to handle, utilizes a built-in barometer, and has been drop tested to ensure the design offers years of rugged field service.

The display and keypad are backlit and the display can be read when using polarized glasses. A Help function guides the user through the menu. The instrument can log and store 5,000 data sets and maintain up top 100 GLP Compliance files all of which are available via the Data Management software and USB port.

The ProPlus reads up to 4 standard YSI water quality sensors on a single “Quatro” cable. Field cables are available in lengths from 1 to 30 meters, longer for D.O. only cables. Lab cables are available in 1-4 meters depending on the sensor selection. Use sensors purchased separately to populate the 4 available ports.
