Oakton DO 300 Meter

• A fast response and minimal maintenance.

These completely waterproof meters read dissolved oxygen (D.O.) in mg/L, ppm or percent saturation. They automatically calculate barometric pressure and salinity offset values so you don’t have to. They also ensure high accuracy with independent 100%, zero and offset adjustment capabilities.

Each meter includes an easy-to-service DO/temperature probe, electrolyte solution and batteries. They have a hold function, a ready indicator and automatically shut off after 30 minutes of nonuse. Nos. 78074 and 78075 additionally feature a backlit display for taking readings in the dark. Waterproof and dustproof No. 78260 also has a backlit display for easy reading of pH, dissolved oxygen and temperature measurements. Can toggle between dissolved oxygen/temperature and pH/temperature. Features push-button pH calibration at five points with automatic buffer recognition. The meter’s two-point D.O. calibration includes an offset function for comparison to titration results. Salinity and atmospheric pressure compensation provide best accuracy. Meter floats for easy recovery if dropped in water. Automatic temperature compensation.

Compliance: IP67 rating.
