RDOX Optical Dissolved Oxygen Probe
The ChemScan rugged dissolved oxygen (RDO) RDOX probe, with its proprietary membrane protection layer, is the most abrasion-resistant optical DO probe available for measuring dissolved oxygen (DO) in demanding wastewater process environments. The RDO EPA Approved Method allows NPDES permit holders to monitor influent, effluent and treatment processes. The RDOX probe is immediately auto calibrated upon cap installation for ease of use and high accuracy.
RDO EPA Approved Method
The RDOX® luminescence quenching sensors have been proven through extensive lab testing and the methodology has been approved by the United States EPA. DO concentration is derived from measuring the luminescence lifetime based on the phase shift between red returned light from the excited lumiphore molecules and the red reference light from the red LED. The RDOX does not consume oxygen and does not require water movement for accurate measurements.
RDOX Smart Sensor Cap
RDOX Smart Sensor Cap – Optical DO sensing foils typically show a high degree of response variability batch to batch and need specific calibration coefficients. Every RDOX foil is calibrated at 90 discrete points and the calibration coefficients are stored in a memory chip embedded in the cap.
A unique, three-layer system provides unmatched chemical and abrasion resistance, extending the life of the sensor cap and expanding the range of compatible conditions.
Instant Hydration Conditioning
Unlike other DO sensors, the RDOX formulation doesn’t require 12-24 hours of hydration conditioning and reads accurately within 90 seconds of going from dry to wet conditions.
RDOX mini Calibration Cup
The RDOX uses only 50 mL of calibration solution for both rinsing and calibration. This feature reduces the calibration cost by 5x over traditional methods, saving thousands of dollars in calibration solution per year.
In-Situ performs a multi-point factory calibration on every sensor. This calibration ensures that the sensor is linear across its full range and reduces the complexity of user calibration.
