Wet Gas Monitoring Solutions for Stack Emissions and Industrial Process Applications

ProDetec supplies wet gas monitor solutions to refineries, power stations, biogas plants, pulp and paper mills, and chemical processing sites across Australia. Our systems measure gas concentrations continuously and in-situ, directly in hot, wet stack and process gas streams, so you avoid the cost and maintenance of extractive sample conditioning. 

Conventional extractive analysers require the wet gas sample to be dried before measurement, introducing sample handling components that create ongoing maintenance demands and potential measurement errors, particularly in applications involving wet gas compressor monitoring, where moisture content and process conditions vary continuously.

ProDetec’s wet gas monitoring solutions are built on the Neo Monitors LaserGas range, using Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology to measure gases including CO, CH4, O2, and H2O directly in the process stream in real time. The LaserGas iQ2 measures up to four gases plus process temperature in a single in-situ unit, so one analyser can replace several across a wet gas monitor installation. It offers fast response, high selectivity and lifetime calibration, with no regular maintenance required.

With over 22 years of experience and local engineering support across Australia, ProDetec supplies, commissions, and supports the full Neo Monitors wet gas monitoring range.

Range of Wet Gas Monitoring Solutions

LaserGasâ„¢ III Single Path

LaserGasâ„¢ III Single Path

LaserGas™ III SP is the third generation in-situ analyzer, designed for safety applications with a special focus on SIL-applications and Ex-d. A compact sized instrument which is easy to install. The instrument is a placed in a sealed housing which eliminates the need for instrument purging. The instrument does not require regular maintenance. 

The monitor is mounted directly onto flanges, which include purge gas connections and a tilting mechanism for easy alignment. Continuous purge flow prevents dust and other contamination from settling on the optical windows. Once power and data lines are connected, measurements are performed in real-time. 

LaserGasâ„¢ III Ultra

LaserGasâ„¢ III Ultra

LaserGas™ III Ultra uses the innovative baseline insensitive TDLAS technique specifically designed for combustion analysis. The Ultra simultaneously meets the requirements of combustion control and safety. That is, high measurement accuracy and high dynamic range with simultaneous real-time measurement capability. 

Applications with very long path lengths and high gas concentrations are no problem for the Ultra. Thanks to the baseline insensitivity and the use of the proprietary IROSS signal processing, high measurement accuracy is achieved even with complex gas mixtures. 

The LaserGas™ III Ultra CO together with the LaserGas™ III O2 is the perfect combination for proper combustion control and safety. 

LaserGasâ„¢ III Ultra

LaserInspectâ„¢ CIMO4

NEO Monitors’ LaserInspect™ CIMO4 gives the operator the opportunity to remotely operate up to 4 LaserGas™ analysers from the same display. The operator has full status overview in an instance of all instruments and can perform maintenance tasks directly from the panel. This HMI is designed for the NEO Monitors LaserGas™ family and can easily be integrated into a cabinet. 

LaserGasâ„¢ II Multi Pass

LaserGasâ„¢ II Single Path

LaserGas™ II SP (Single Path) is a non-contact optical measurement method also known as in-situ. The analyser is suitable for variety of gases and process conditions, including dual gas measurements.
Laser Gas™ II SP has also a wide range of Ex-certifications, including IECEx, ATEX, CSA. 

The instrument does not require any consumables and does not require regular maintenance. The absence of extractive conditioning systems further improves availability of the measurements and eliminates errors related to sample handling. 

Once power, data lines and purge are connected, the instrument is ready to use and measurements are performed in real-time. 

LaserGasâ„¢ Q ICL

LaserGasâ„¢ Q ICL

Unlike the previous generations of LaserGas™ products, the LaserGas™ Q family measures in the mid-infrared spectrum which allows for better detection limits. As well as detection of gases not obtainable with the more common near-infrared spectroscopy. 

The sensor has low maintenance cost and does not require regular maintenance. The absence of extractive conditioning systems further improves availability of the measurements and eliminates errors related to sample handling. 

The monitor is mounted directly onto flanges, which include purge gas connections and a tilting mechanism for easy alignment. Continuous purge flow prevents dust and other contamination from settling on the optical windows. Once power and data lines are connected, measurements are performed in real-time. 

LaserGasâ„¢ II Multi Pass

LaserGasâ„¢ II Multi Pass

LaserGas™ II Multi Pass combines extractive measurement with a compact analyser design. The laser beam is coupled into a measurement cell, where it is reflected multiple times between two spherical mirrors to enhance the analyser sensitivity. 

The monitor is a turn-key instrument. No other operations than connecting power, sample gas tubes and optional purge are required during installation. LaserGas™ MP provides a reliable and easy to use solution for a wide variety of applications. 

EXO Dust Monitor for Wet Gases

EXO Dust Monitor for Wet Gases

The EXO (EXtractive Optical PM Monitor) for CEMS is a continuous particulate emissions monitoring system (PM-CEMS) designed for accurate dust measurement in wet and condensing process environments. Ideal for applications downstream of wet scrubbers, the EXO uses extractive, isokinetic sampling with a heated probe to eliminate moisture before measurement. Its advanced optical forward scattering technology delivers reliable, continuous particulate concentration readings, while the integrated touchscreen interface provides real-time data in mg/m³ or 4–20 mA outputs. Supplied in a robust weatherproof enclosure, the EXO offers dependable performance for industrial stack emissions monitoring and supports compliance with environmental monitoring requirements.
