Amperometric Sensors with Advanced Membrane Technology

The robust membrane design withstands oil-rich wastewater and mechanical abrasion, ensuring stable data without frequent sensor cleaning.

Minimal polarization time allows for rapid deployment and maintains zero-point stability even during prolonged disinfectant absence.

Space-Saving DUC Series Universal Digital Controllers

The DUC series features an ultra-compact 100x100mm form factor that supports both panel-mount and wall-mount configurations, significantly maximizing internal cabinet space and reducing installation overhead in high-density electrical enclosures.

Engineered for global deployment, the controller integrates a versatile power module that adapts to either 100~240V AC or 18~36V DC inputs, ensuring continuous system stability in remote monitoring sites with fluctuating voltage conditions.

Empowering You to Achieve Process Excellence with Precision Disinfection Monitoring

About Disinfectant

Our sensors employ advanced amperometric membrane technology to selectively permeate disinfectant molecules while effectively blocking ions and particles from interfering with the measurement. Inside the electrolyte-filled chamber, a precise electrochemical reaction converts the concentration into a stable, linear electrical signal. Integrated algorithms then apply real-time pH and temperature compensation to ensure consistent accuracy across varying water conditions and industrial environments.

Our monitoring solutions help you minimize the ecological impact of disinfectant residuals by ensuring precise dosing that prevents water-borne eco-toxicity. This proactive control supports your commitment to environmental sustainability by reducing chemical discharge and lowering the overall carbon footprint of your water treatment processes.

Frequently Asked Questions

1. How do I choose the right sensor for chlorine dioxide vs. free chlorine?
Selecting the correct sensor depends on your specific application and water chemistry to avoid cross-sensitivity and ensure accurate disinfection control.
2. Why is pH compensation critical for accurate free chlorine measurement?
Since the ratio of HOCl to OCl- changes with pH, integrated compensation is essential to calculate the true active free chlorine concentration.
3. What are the advantages of membrane-covered amperometric sensors?
Membrane-covered technology provides high selectivity by allowing only disinfectant molecules to pass while blocking interfering ions and particles.
4. How often should disinfectant sensors be calibrated for stable performance?
While our sensors offer high stability, we recommend monthly calibration checks against a reliable DPD reference to maintain peak operational accuracy.
5. Can these sensors be used in high-salinity seawater applications?
Yes, our specialized sensors are designed with robust materials to resist salt build-up and corrosion in harsh marine or aquaculture environments.
6. What is the typical lifespan of a disinfectant sensor membrane and electrolyte?
Depending on water quality, membranes and electrolytes typically last 6 to 12 months and can be easily replaced to extend the sensor's service life.
7. How does real-time monitoring reduce chemical costs in water treatment?
Continuous tracking prevents both wasteful overdosing and dangerous underdosing, optimizing chemical consumption by matching real-time demand.
8. Are your disinfectant controllers compatible with existing SCADA systems?
Our ADS2 controllers support standard protocols like Modbus RTU and 4-20mA outputs for seamless integration into your existing industrial automation network.
