Smart environmental monitoring solutions
The 4200 dust and opacity monitor is AMETEK Land’s compact, cost-effective solution for the continuous monitoring of dust, smoke and particulates in a wide range of industrial applications. NOTE: The 4200 is currently available only in Asia.
A lightweight design makes installation and positioning simple, even in challenging applications. The low-maintenance design has no moving parts – ensuring it operates reliably and continuously for immediate cost and performance benefits.
Using a single red LED to effectively monitor hot, dirty, or toxic process conditions, 4200 requires only the installation of a transceiver and retro-reflector, fitted on either side of the stack. The system alternates between measurement and flood sources to eliminate drift and ensure accuracy.
Ideally suited to multi-process plants with common exhaust stacks, the 4200 is designed for measurements in power generation, minerals, and industrial boilers.

VERSATILE APPLICATION USE
The 4200’s flexible and reliable measurement makes it ideal for use in a range of applications, including particulate removal systems, combustion efficiency monitoring and precipitator power optimisation.
SIMPLE KEYPAD CONTROL
Easy keypad operation allows straightforward access to the 4200’s functions. Setup, calibration, diagnostic and alarm settings can all be adjusted, providing optimum instrument performance for your process. Measurements can be displayed and output in % opacity or mg/m3.
CUSTOMISE TO YOUR PROCESS NEEDS
Extensive accessories enable users to customise the 4200 to their precise process conditions. Options include air blower/mover systems and waterproof covers.
