The Extech DO700 portable dissolved oxygen meter has automatic salinity compensation and manual barometric pressure compensation for DO measurements. The waterproof housing meets IP57 standards. The Extech DO700 portable dissolved oxygen meter has one button pH calibration (4, 7 and 10 pH) and a choice of 3 point pH calibration for better accuracy. One point conductivity calibration automatically recognizes 8 calibration solutions. The Extech DO700 portable dissolved oxygen meter has automatic temperature compensation (non-linear compensation for purified water, less than 10µS/cm to improve measuring accuracy).

The Extech DO700 portable dissolved oxygen meter's memory stores up to 400 readings with series number, measured value and temperature. The meter has a large blue backlit dual LCD display. The auto power off function saves battery life and also has a disable function.
