The Extech EC600 waterproof conductivity meter has a waterproof housing which meets IP57 standards and automatic one button pH calibration to 4,7, and 10 pH. There is also a choice of 3 point pH calibration for better accuracy. The one point conductivity calibration automatically recognizes 8 calibration solutions.

The Extech EC600 waterproof conductivity meter has automatic temperature compensation (non-linear compensation for purified water 10µS/cm to improve measuring accuracy). The memory stores up to 300 readings with series number, measured value, and temperature. The Extech EC600 waterproof conductivity meter has a large blue backlit dual LCD display. The auto power off saves battery life and also has a disable function.
