For Universal Applications

The HI98193 is a portable DO meter with extended ranges of up to 50 ppm and 100% saturation. HI98193 features compensations for pressure, temperature and salinity, which are essential for an accurate dissolved oxygen reading. HI98193 is supplied with the HI764073 polarographic dissolved oxygen probe that utilizes field replaceable PTFE membrane caps.

BOD results

BOD is calculated in mg per liter from the difference between the initial and final dissolved oxygen concentration readings.

BOD parameters and records

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.

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.
