The 4200+ is the most accurate and reliable monitor available for dust and opacity measurements in combustion applications not requiring automatic calibration checks.

Optimized for multi-process plants, 4200+ delivers you immediate performance and cost benefits through an easy installation, simple operation, and low maintenance requirements.

A highly homogenous green LED light source, glass multi-prism retro-reflector and flood LED minimize sensitivity to changes in alignment and ambient temperature: this ensures low optical and electronic drift, giving the exceptionally accurate, stable measurement you need.

Ideal for combustion applications where an automatic calibration check is not required, the 4200+ is suitable for use power generation, industrial boilers, and pulp & paper industries.
