The portable Dissolved Oxygen Meter of Hanna Instruments is a waterproof meter with a digital optical electrode and an extended measuring range up to 50 ppm and 500% saturation.
The meter automatically compensates for dissolved oxygen concentrations. Temperature and atmospheric pressure compensations are performed automatically. Salinity compensation can be entered manually.
Pressure compensation can be validated against a reference barometer using the built-in barometer and can be re-calibrated as required in user selectable units (mmHg, inHg, atm, psi, kPa, mbar).
