HI-98193 Professional Waterproof Dissolved Oxygen and BOD Meter
HI-98193 Professional Waterproof Dissolved Oxygen and BOD Meter
The HI-98193 is a robust and versatile portable dissolved oxygen (DO) and BOD meter designed for demanding field and laboratory environments. It delivers accurate DO measurements in both mg/L (up to 50.00) and % saturation (up to 600%), ideal for environmental monitoring, wastewater analysis, and process control.
This meter stands out for its advanced compensation features:
- Salinity compensation: Direct determination of DO in saline waters.
- Automatic temperature compensation: Built-in sensor with one or two-point calibration for reliable accuracy.
- Pressure compensation: Built-in barometer, user-selectable and recalibratable, eliminates external charts or altimeter needs.
In addition to standard DO readings, the HI-98193 offers built-in measurement modes and automatic calculations for:
- Biochemical Oxygen Demand (BOD)
- Oxygen Uptake Rate (OUR)
- Specific Oxygen Uptake Rate (SOUR)
Other essential features include:
- Quick connect probe: HI-764073 polarographic DO probe with easy DIN connection.
- Data logging: Store up to 400 samples, transfer via USB to PC with HI-92000 software.
- GLP compliance & on-screen help: Instant access to calibration and measurement data; contextual help menus for easy troubleshooting.
- Rugged, IP67 waterproof enclosure: Built for challenging environments.
- Extensive accessory set: Includes probe, electrolyte solutions, membrane caps, software, cables, beakers, batteries, and rugged carrying case.
On-screen Features
- BOD, OUR, SOUR results are calculated and displayed in real time.
- All necessary parameters for BOD testing can be set and viewed at once.
- List and review all saved BOD data with ease.
