Model 4200 Process and Non-Compliance Opacity Monitor
The Model 4200 is a more compact design, whilst benefiting from the same advanced measurement technology. It is aimed at both cost sensitive applications and requirements to monitor multiple ducts on a single plant. It has a lowest measuring range of 0 - 20 % up to a 100% maximum . >>>

Model 4500 MkII⁺ Opacity Compliance Monitor
The Model 4500 MkII⁺ is designed specifically for environmental compliance monitoring applications.
It has a lowest measuring range of 0 - 20 % opacity with a maximum dust burden of 4000 mg/m³.
This opacity monitor carries a wide range of compliance and performance approvals including those from the US-EPA and the ASTM. >>>

Model 4500 Premier Opacity Compliance Monitor
The Model 4500 Premier is the most sensitive monitor in the range, aimed at very low dust applications.
It gives a lowest measuring range of 0 - 10 % opacity and is ideally suited to CPS-001 and other low dust applications, where high accuracy and low drift are required. This opacity monitor carries a wide range of compliance and performance approvals including those from the US-EPA and the ASTM. >>>
