OAKTON pH/DO 300

Convenience of three meters in one!

These completely waterproof meters read dissolved oxygen 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. Features a backlit display for taking readings in the dark. Toggles between dissolved oxygen/temperature and pH/temperature. Features push-button pH calibration at five points with automatic buffer recognition. Meter's two-point DO 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. pH/DO Accessory Kit includes calibration solutions, electrolyte solution, rinse bottle and hard carrying case. Meter not included.
