Understanding Oil in Water Monitoring and Its Importance

An oil-in-water monitor is a crucial device used across industries to detect and measure hydrocarbon contamination in water systems. Whether for industrial process water, cooling towers, steam condensate, or wastewater treatment, ensuring that water remains free from harmful oil contamination is essential for environmental compliance, equipment protection, and operational efficiency.

Oil contamination in water can lead to clogged filters, reduced heat exchanger efficiency, environmental fines, and costly downtime. Industries worldwide rely on high-performance monitors, oil-in-water sensors, and oil-in-water analysers to provide real-time, highly accurate hydrocarbon measurements.

With over 50 years of expertise in oil-in-water analysis, PMA has been at the forefront of providing cutting-edge technology that ensures precise, reliable, and cost-effective monitoring solutions.

TD-120 – The Industry’s Most Advanced Oil in Water Monitor

The TD-120 Oil in Water Monitor is designed for real-time, high-accuracy hydrocarbon detection, making it the perfect solution for critical water quality monitoring applications. Engineered with UV fluorescence technology, the TD-120 delivers instant, precise readings from low PPB (parts per billion) levels up to 6,000 PPM (parts per million).

What makes the TD-120 the best oil-in-water analyser?

Unmatched Accuracy & Sensitivity

• UV fluorescence technology ensures the detection of even the slightest traces of hydrocarbons.
• Detection ranges from PPB to 6,000 PPM, providing versatile application monitoring.
• Auto-calibration capabilities ensure long-term accuracy with minimal operator intervention.

Instant Response Time – Less than 1 Second!

• Unlike other oil-in-water sensors that take minutes to respond, the TD-120 provides real-time data in under a second, allowing for immediate action and process optimisation.

Low Cost of Ownership – No Reagents, No Hassle!

• Many traditional oil-in-water analysers require expensive consumables, but the TD-120 operates without reagents or additional instrumentation, making it a cost-effective solution.
• Minimal maintenance required, saving you time and money.

Smart, User-Friendly Interface

• Internal tablet interface for quick setup and calibration.
• Local colour display provides easy-to-read PPM, PPB, or raw signal data results.
• External touchpad for event logs and maintenance tracking.

Built for Harsh Industrial Environments

• 316 Stainless Steel Enclosure (NEMA 4X/IP66 rated) ensures maximum durability.
• New Auto-Valve Capabilities:
• Temperature Protection – Ensures stable performance in extreme conditions.
• Fresh Water Flush – Keeps the system clean and running efficiently.
• Process Isolation – Prevents external factors from interfering with readings.
• Certified to ISO 9001, 14001, and 45001 standards – Quality, environmental responsibility, and safety guaranteed.

Real-World Applications – Why You Need the TD-120 Oil-in Water Sensor

Boiler & Steam Condensate Monitoring – Protecting Your Equipment & Efficiency

Boilers and steam systems are susceptible to hydrocarbon contamination, which damages heat exchangers, reduces efficiency, and leads to costly shutdowns. The TD-120 continuously monitors steam condensate and boiler feed water, ensuring zero oil contamination and extending boiler life.

Cooling Tower & Heat Exchanger Protection – Preventing Costly Damage

Heat exchangers and cooling towers require clean water to operate efficiently. Even small traces of hydrocarbons can lead to scaling, fouling, and heat transfer inefficiencies. The TD-120’s rapid detection capabilities ensure that oil leaks are identified immediately, preventing long-term damage and reducing maintenance costs.

Intake Water & Environmental Protection – Meeting Compliance Standards

Industries that rely on natural sources must ensure their water intake is free from hydrocarbon contamination. The TD-120 provides real-time data to help companies meet strict regulatory requirements and prevent pollution incidents, whether for drinking water treatment, industrial use, or environmental protection.

Dam Sumps & Wastewater Treatment – Optimising Water Quality

The TD-120 oil-in-water analyser is perfect for detecting hydrocarbon contamination in sumps, wastewater treatment plants, and industrial drainage systems. Its PPB-level sensitivity ensures that even the most minor traces of oil are identified, allowing industries to optimise treatment processes and prevent environmental discharge violations.

Industrial Process Water Monitoring – Maximising Efficiency

For industries that use water in manufacturing or refining processes, ensuring oil-free water is critical to maintaining efficiency and preventing product contamination. The TD-120 helps optimise oil separation processes, reduce downtime, and improve operational efficiency.
