Combining the unique features of three patented technologies, the 4200+ achieves the highest possible specification for the fundamental performance parameters for an opacity monitor, with no moving parts.
The Model 4200+ is a compact smoke, dust and particulate monitor for measuring dust emission concentrations on industrial processes and non-compliance applications. This dust monitor is ideally suited to multiprocess plants with common exhaust stacks.
