The Extech EC600 is a 7-in-1 waterproof meter that measures conductivity, TDS, salinity, resistivity, pH, mV, and temperature with lab-quality performance. Its IP57 waterproof housing provides reliable operation in demanding field environments.

The meter features automatic one-button pH calibration for 4, 7, and 10 pH with an optional three-point calibration for enhanced accuracy. One-point conductivity calibration automatically recognizes eight calibration solutions from USA, Europe, and China series. Automatic temperature compensation includes non-linear compensation for purified water below 10µS/cm to improve measurement accuracy.

Memory storage holds up to 300 readings with series numbers, measured values, and temperatures. The large blue backlit dual LCD display ensures clear viewing in all conditions. Auto power off with disable function conserves battery life.

Complete kit includes pH/mV/temperature electrode, polymer conductivity cell, pH calibration solutions (4, 7, and 10pH), conductivity calibration solution (1413µS), 2 AA batteries, and hard carrying case. Ideal for water quality testing, environmental monitoring, and laboratory applications.
