AMETEK-Land 4200+

The 4200+ 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, 4200+ 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 4200+ is suitable for use power generation, industrial boilers and pulp & paper industries.

A TRUSTED COMBUSTION MEASUREMENT
The 4200+ accurately measures dust and opacity levels across key combustion processes, including electricity generating units, industrial boilers, furnaces, kilns and dust collectors.

TROUBLE-FREE OPERATION
Lightweight and compact, the 4200+ is designed to operate easily, with no moving parts to ensure high reliability. The menu tree is intuitive, using text and icon prompts. A manual calibration check can be performed while the process is running.

WIDE OPERATING TEMPERATURE RANGE
Suitable for monitoring dust and opacity across an extensive range of combustion processes, the 4200+ operates from -40 °C to 55 °C (-40 °F to 131 °F). This brings unprecedented flexibility to a wide variety of applications.

Applications

  • Biomass
  • Cement
  • Chemical Processing
  • Emissions Monitoring
  • Iron to Steel
  • Lime
  • Paper
