Hanna Optical Dissolved Oxygen Meter / water testing HI98198

The HI98198 Optical Dissolved Oxygen Meter is a portable water-testing instrument for measuring dissolved oxygen in fresh and salt water using enhanced optical dissolved oxygen technology. The meter provides fast, stable readings with a Quick Connect digital optical DO probe and built-in calculations for Biological Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR), making it suitable for field and laboratory water quality testing.

Key Features:

• Model: HI98198 Optical Dissolved Oxygen Meter
• DO range: 0.00 to 50.00 mg/L and 0.0 to 500.0% saturation
• Temperature range: -5.0 to 50.0 °C (23 to 122 °F); temperature resolution 0.1 °C
• Barometric pressure range: 420 to 850 mmHg with 1 mmHg resolution
• Data logging: log-on-demand up to 4000 records; GLP data (last 5 calibrations)
• Connectivity: USB-C data export (.csv)
• Power: 4 × 1.5V AA batteries; dimensions 185 × 93 × 35.2 mm; weight with batteries 450 g

Advantages:

• Optical DO technology and Smart Cap probe eliminate membranes, electrolyte and warm-up time for low maintenance, ready-to-use measurements.
• Rugged, waterproof (IP67) meter and IP68-rated probe with protective guard provide reliable field performance in harsh environments.
• Built-in methods (BOD, OUR, SOUR), GLP traceability and onboard logging simplify compliant data collection and reporting.
• Quick Connect probe and USB-C export enable fast probe replacement and straightforward data transfer to computers or storage devices.
