Fluorescence measurement is employed to detect the presence of polycyclic aromatic hydrocarbons (PAHs) in water. The device stimulates the PAHs with UV light and detects the fluorescent radiation emitted by them as a result.
Product Introduction
Desun Uniwill PAH Measurement Sensors, designed for detecting Polycyclic Aromatic Hydrocarbons, is a cutting-edge device revolutionizing environmental monitoring. PAHs are organic pollutants with diverse sources, emphasizing the critical need for real-time monitoring to control pollution and assess associated risks effectively.
Desun Uniwill Online PAHs (Polycyclic Aromatic Hydrocarbons) Sensor works in the measuring principle of UV fluorescence, it’s more sensitive and specific than the conventional infrared scattering or absorption methods. This makes it possible to determine the smallest traces of PAHs, e.g. in drinking water, but also in cooling water condensates. It has an RS-485 interface that allows easy and fast sensor configuration via Modbus.
Features:
-PAH Measurement Range: 0 – 1000 ppb (µg/L)
-Equipped with an RS-485 interface that enables simple and quick
sensor configuration via Modbus
-In situ measurement, no sampling no reagents
-Installations on the inlet and outlet of the scrubber
-Fluorescence probe for PAH/Oil in water measurements
-Corrosion-free Housing
-Detects oil in water through UV fluorescence
-Real-time in-line measurement
-Simple installation and operation
PAH Testing Purpose
1. Trace oil in water
2. Leak detection
3. Oil Spill Monitoring
4. Water Quality Monitoring
5. Hydrocarbons monitoring in water
6. Oil in Water Monitoring
PAH Monitoring Medium
1. Ballast Water
2. Discharge Water
3. Industrial Wastewater
4. Drinking Water
5. Washing Water
6. Cooling water & condensate return
7. Process water (refineries, desalination plants)
8. Rainwater (airport runoff monitoring)

There are two measurement modes to choose from:
1. Analyzer mode,
Combine the instrument with a flow-through tank to lead the liquid into the glass tube for measurement.
2. Probe mode,
Online measurement of PAH (oil) content in water by UV fluorescence method with fast response and high sensitivity.
No need for sampling and sample preparation, no reagents.
Can be connected to supporting instrumentation, and can achieve 4-20mA analog output, to achieve a variety of control methods.
The field of application ranges from petrochemistry, and leakage detection in cooling and wastewater streams to environmental monitoring.
Desun Uniwill specializes in the design, development, and manufacture of a range of water quality monitoring sensors and controllers. PAH sensors are our latest sensors and are mainly used in marine exhaust gas cleaning systems.
