Portable dissolved oxygen meter

The HI98198 Portable Dissolved Oxygen Meter is a waterproof meter with a digital optical electrode and an extended measuring range of up to 50 ppm and 500% saturation.

The HI98198 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 recalibrated as required in user selectable units (mmHg, inHg, atm, psi, kPa, mbar). The meter has two virtual keys that guide you through configuration, settings and data logging. The interface is intuitive and therefore suitable for every user.
