HM-500 Oil in Water Sensor
Accurate. Reliable. Built for real-world conditions.
The HM-500 Oil in Water Sensor is designed to deliver precise oil concentration measurement in challenging water environments. Using advanced UV fluorescence technology at 365 nm, it provides accurate readings across a 0–10 ppm range – even in the presence of colour and turbidity.
Unlike conventional sensors, the HM-500 automatically compensates for interference (up to 150 NTU), ensuring consistent performance where other instruments struggle.
Practical Benefits
- Reduce maintenance time
- Improve measurement confidence
- Minimise downtime
- Ensure compliance with discharge limits
Typical Applications
The HM-500 is ideal for a wide range of industrial and water treatment applications, including:
- Heat exchanger leak detection
- Oil tank leakage detection
- Intake water monitoring (UF & RO feedwater)
- Reinjection water monitoring
- Industrial wastewater monitoring
- Marine discharge monitoring
- Plant runoff and stormwater monitoring
Ready for Integration
The HM-500 is built for reliable, continuous operation and integrates easily into existing monitoring and control systems – delivering dependable, real-time oil-in-water measurement where it matters most.
