AMETEK Land - Model 4400 - Opacity and Dust Monitor
The 4400 is the most accurate and reliable monitor available for dust and opacity measurements in combustion applications not requiring automatic calibration checks.
Optimised for multi-process plants, 4400 delivers you immediate performance and cost benefits through easy installation, simple operation and low maintenance requirements.
A highly homogenous green LED light source, glass multi-prism retro-reflector and flood LED minimise 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 440 is suitable for use power generation, industrial boilers and pulp & paper industries.
