Reduce your Total Cost of Ownership (TCO) with Optical DO sensors. Features include long-lasting sensor caps, instant warm-up, and high stability in harsh environments.
Zero Warm-up Time: Unlike polarographic sensors that require up to 30 minutes of polarization, optical sensors provide instantaneous readings upon power-up.
No Flow Requirement: Since the sensor does not consume oxygen during measurement, it provides accurate data in stagnant water without the need for stirrers or constant flow.
Plug-and-Play Integration: Most modern units utilize Digital Communication (Modbus RS485), allowing for seamless integration into existing PLC or SCADA systems with minimal wiring.
Consumable-Free Body: Eliminates the need for hazardous electrolyte solutions, fragile membranes, or anode/cathode cleaning.
Long-Life Sensing Caps: The luminescent caps typically last 1 to 2 years, meaning maintenance is reduced to a simple, once-a-year “twist-off, twist-on” replacement.
Extended Calibration Stability: Optical technology is inherently more stable; these sensors can hold their calibration for several months, drastically reducing the labor hours required for field technicians.
Interference Resistance: Completely unaffected by common “poisoning” gases like Hydrogen Sulfide ($H_2S$) or wastewater chemicals that typically destroy electrochemical membranes.
Automatic Compensation: Built-in sensors provide real-time corrections for Temperature and Barometric Pressure, ensuring $mg/L$ accuracy across varying environmental altitudes and climates.
Rugged Construction: Available in 316L Stainless Steel or Titanium, making them ideal for everything from corrosive salt-water aquaculture to industrial chemical processing.
