OAKTON® Waterproof pH / DO Meter

Waterproof pH / DO Meter Gives You the Convenience of Three Meters in One

This completely Waterproof pH / DO Meter reads dissolved oxygen in mg/L, ppm or percent saturation. They automatically calculate barometric pressure and salinity offset values so you don't have to. It also ensures high accuracy with independent 100%, zero and offset adjustment capabilities.Meter features a hold function, a ready indicator and auto shut-off after 30 minutes of inactivity. Backlit display makes readings in the dark easy. Toggle between dissolved oxygen/temperature and pH/temperature. Push-button pH calibration at five points with automatic buffer recognition. Two-point DO calibration includes an offset function for comparison to titration results. Salinity and atmospheric pressure compensation provide best accuracy. Automatic temperature compensation. Floats for easy recovery if dropped in water.
