Product Introduction
Desun Uniwill PAH Monitoring 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

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.
Applications:
-Environmental Monitoring: Detecting PAH levels in the air, especially in urban and industrial areas.
-Occupational Health: Monitoring PAH exposure in workplaces like manufacturing plants, refineries, and construction sites.
-Disaster Response: Assessing air quality during and after events like wildfires or chemical spills.
-Indoor Air Quality: Monitoring PAH levels in homes and buildings, particularly those using solid fuels for heating or cooking.
Polycyclic Aromatic Hydrocarbons (PAHs) are a group of organic compounds with multiple aromatic rings. They are found in the environment primarily due to incomplete combustion of organic matter and are known for their potential health hazards. Real-time PAH sensors are crucial for monitoring air quality, especially in industrial areas or regions affected by wildfires.
