The new addition to the Environmental Express Oakton product line features updates to measuring water quality easier and faster. The larger display is 2.75×2.0" for better viewing angle, has indicators for battery life, stability, and calibration. It shows both the parameter and temperature measurements at the same time.

The meter is a perfect combination of the most advanced electronics technology, sensor technology, and software design all while being the most cost-effective portable electrochemical meter. The microprocessor-based meter features automatic calibration, automatic temperature, salinity compensation, function set-up, self-diagnostics, automatic power-off, and low voltage display.

DO100 portable meters come with a polarographic electrode and a special DO calibration sleeve, taking only three to five minutes to polarize. The electrode also comes with three combined membrane caps so the membrane can be easily replaced.
