Optical RDO PRO-X Dissolved Oxygen Probe for Process Monitoring Applications0 pages
Innovations in
Water Monitoring
Optical RDO® PRO-X Dissolved Oxygen Probe
The In-Situ® Rugged Dissolved Oxygen (RDO)
PRO-X Probe uses optical technology for
measuring dissolved oxygen (DO) in demanding
process environments. The U.S. Environmental
Protection Agency (EPA) has approved In-Situ RDO
methods for use in Clean Water Act programs.
NPDES permit holders can use the RDO PRO-X Probe and
Con TROLL® PRO System for monitoring influent, effluent, and
treatment processes. Visit the In-Situ website for details and
start using breakthrough technology.

Runs aerators efficiently and mitigates risks
Eliminates the need for a costly transmitter or controller,
and requires only 8 to 36 VDC power
Includes complete instrument with a standard 10-m cable
Resists abrasion and photobleaching effects
Withstands high salinity environments—Inert, non-corrosive
materials used to construct probe body and sensor
Insensitive to interferences that plague membrane-based
sensors (hydrogen sulfide, chloride, ammonium, and others)

Includes diagnostic tools to help you evaluate sensor health
Provides ±0.1 mg/L accuracy from 0 to 8 mg/L; ±0.2 mg/L
accuracy from 8 to 20 mg/L; and ±10% of reading from
20 to 50 mg/L
Operates with very low drift for long periods of time
Responds quickly to oxygen and temperature changes
Delivers consistent, reproducible results (<0.05 mg/L)
