The RDO PRO-X Probe is EPA-approved for Clean Water Act programs, using optical technology to measure dissolved oxygen and temperature in demanding process environments. The RDO PRO-X Probe lets NPDES permit holders monitor influent, effluent and treatment processes, responding quickly to oxygen and temperature changes for more accurate results.

This durable probe requires no calibration, conditioning, or membranes. The sensor cap automates setup, storing calibration coefficients, serial number, and expiration date. When cap expires, simply snap it off and pop on a new one.
