HI98198 Optical Dissolved Oxygen Meter Professional dissolved oxygen measurement with digital optical probe Design Features • Digital optical probe with Quick Connect • IP67 rated waterproof, rugged enclosure • Clear, dot matrix, back-lit display with multifunction virtual keys • A dedicated HELP key for assistance anytime. Technical Features • Percent saturation or concentration measurements (mg/L) • One or two-point calibration at 0 or/and 100% saturation (with auto recognition). • Automatic temperature compensation with one-point temperature calibration • Salinity compensation · Salinity compensation allows for direct determination of dissolved oxygen in saline waters. · Users can set the salinity value • A user selectable “Calibration due” warning. • Built-in calculations · Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR) modes • Built-in barometer · Automatic barometric pressure compensation with 1 point calibration · Displays pressure in user-selectable units (mmHg, inHg, atm, psi, kPa, mbar) • Log on demand with 4000 records capability. • AutoEnd freezes the next stable measurement value on the display. • GLP · A dedicated GLP key that includes at last 5 calibrations with time, date, calibration points as well as barometric pressure, temperature and salinity setting. • USB-C port for easy data transfer to memory stick, PC or other compatible device • Displays temperature in °C or °F • Approximately 200 hours of continuous use using 4 AA batteries The HI98198 opdo™ meter is a rugged, portable dedicated dissolved oxygen (DO) meter designed for fresh and saltwater measurements of dissolved oxygen. This professional, waterproof meter complies with IP67 standards and measures DO, barometric pressure, and temperature. The HI98198 is supplied with a HI764113 digital optical dissolved oxygen probe in a custom thermoformed durable carrying case with accessories. It is compact and ergonomically designed to provide ready access to the materials required for routine sampling. The HI98198 opdo meter is only compatible with the Hanna HI764113 digital dissolved oxygen probe. Concentration measurements are automatically compensated for barometric pressure, temperature and salinity. Barometric pressure and temperature are automatically measured and compensated. Salinity is automatically compensated by setting manually the salinity concentration of the water being measured. The meter also has a built in application to measure and calculate BOD (Biological Oxygen Demand), OUR (Oxygen uptake rate), and SOUR (Specic Oxygen Update Rate). 6 Dissolved Oxygen 6.22 | www.hannainst.com portable
