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.
