Hanna Instruments HI98193 Waterproof Portable Dissolved Oxygen and BOD Meter
A tough, transportable dissolved oxygen (DO) meter for demanding applications is the HI98193. This expert, IP67-compliant, waterproof meter measures temperature, DO, barometric pressure, and BOD. All necessary tools for performing a DO measurement are included with the HI98193, which is delivered in a sturdy carrying case.
- Preformed PTFE Membrane
- Quick Connect
- Ergonomic, One-Handed Operation
On-screen Features
BOD is calculated in mg per liter from the difference between the initial and final dissolved oxygen concentration readings.
All necessary parameters for BOD testing can be set and displayed at once.
A list of all saved BOD data can be easily retrieved and shown on the LCD display.
Measured in mg of oxygen consumed per L per hour.
Measured in mg of oxygen consumed per g of volatile suspended solids per hour.
