Cole-Parmer Oakton DO2700 Benchtop Dissolved Oxygen Meter with NIST-Traceable Calibration

Oakton DO 2700 meter measures dissolved oxygen in mg/L, ppm, or % saturation with simultaneous temperature display in °F or °C. Large LCD features annunciators to aid in meter use and troubleshooting. Large display size makes viewing measurements easier. Meter is encased in a compact housing which takes up a minimum of bench space. Water-resistant membrane keypad and convenient pullout reference guide provide useful features for the lab. Meter meets GLP requirements — all calibration and measurement data is stored with a time/date stamp. Bundled self-stirring probe and bi-directional RS-232 make this meter ideal for BOD and other advanced dissolved oxygen applications. Nonvolatile memory stores up to 500 data sets to simplify documenting data. Oversized graphic LCD with backlight allows readings under all conditions.
