The YSI EcoSense Pen-Style Conductivity & Temperature meter is waterproof and can be operated with one hand. It has a graphic user interface for ease of use, and a "hold" feature to lock the reading on the display.
This meter displays conductivity or TDS and temperature and auto-ranges over both units. Use 1 or 2 point calibration. The electrode is user replaceable.
