Opacity and Dust Monitors

4200+ (Opacity)

Dust and opacity monitor for monitoring combustion processes where automatic calibration checks are not needed.

Overview +

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.

The 4200+ is AMETEK Land’s advanced, compact monitor for opacity and dust.

*4500 MkIII is recommended for measurements requiring automatic zero and upscale checks, as specified by ASTM D6216 and US EPA Performance Specification 1.

- An Introduction to Opacity Monitoring
  
  This presentation looks at how you can measure 'something' which you are required to measure by the environmental agency in the country in which you are operating, particularly the opacity.
- Thermal Imager Continuously Monitors Industrial Gas Applications
  
  With the AMETEK Land NIR-B 3XR thermal process imager, operators of industrial gas applications can continuously monitor tube wall temperatures within a live thermal scene. The NIR-B 3XR is easy to install via a small hole through the furnace wall, and its wide 90-degree horizontal field-of-view provides coverage for many tubes with just a single device. More than 320,000 temperature measuring pixels help the operator to continuously define and monitor spots, areas, and profiles - even in hazardous areas. In addition, the high-quality optics afford detailed views of anomalies like flame impingement and coking tubes.
- Measuring Opacity and Particulate Emissions From Combustion Processes
  
  An opacity monitor provides a simple and robust means for emissions monitoring in combustion processes, but under some conditions a particulate matter (PM) monitor may be necessary. This webinar will introduce the concepts behind opacity and particulate measurement, describe the key technologies and provide detailed insight into the requirements for a successful installation.
