Product Overview
The AZ Waterproof EC and TDS Pen provides reliable real-time readings of electrical conductivity (EC), total dissolved solids (TDS), and water temperature. Featuring a large dual-display LCD, it allows you to easily switch between EC (µS/mS) or TDS (ppm) and temperature values with automatic temperature compensation for consistent accuracy. The IP65-rated keypad safeguards against splashes and field use, while a handy hold function freezes readings for better visibility. With an adjustable TDS factor, auto-power-off, and one-button calibration, this compact pen delivers professional-level precision in an easy-to-use, portable package. Ideal for hydroponics, aquaculture, pool care, and general water quality monitoring.
Batteries Included.
