AMETEK-Land 4200

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 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.
