HI-98193
The Hanna HI-98193 has extended ranges of up to 50 ppm and 600% saturation. The Dissolved Oxygen and BOD Meter includes measurement, methods and calculations for BOD, OUR, and SOUR. It can also compensate for changes in barometric pressure with the internal barometer.
Key Features
- Quick connect probe - The HI-764073 polarographic dissolved oxygen probe features a quick connect DIN connector to make attaching and removing the probe simple and easy.
- Data Logging - The HI-98193s log-on demand features allow users to store up to 400 samples that can be later transferred to a PC with the HI-920015 USB cable and HI-92000 software.
- GLP and On-Screen Help - Comprehensive GL data is directly accessible by pressing the GLP key; the contextual help menu can be accessed to obtain on-screen information and assistance at the touch of a button.
- IP67-rated waterproof, rugged enclosure
- Salinity compensation - users can set the salinity value
- Automatic pressure compensation - built-in barometer with user-selectable units (mmHg, inHg, atm, psi, kPa, mbar)
- Built-in calculations - determination of Biochemical Oxygen Demand (BOD), Oxygen Uptake Rate (OUR) and Specific Oxygen Uptake Rate (SOUR)
- Automatic polarisation of the probe at startup
- Ready to use PTFE-preformed membrane caps
- Approximately 200 hours of continuous use
- BOD is calculated in mg per litre 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
- OUR results measured in mg of oxygen consumed per L per hour
- SOUR results measured in mg of oxygen consumed per g of volatile suspended solids per hour
