Opacity and Dust Monitors

  • 4200+ (Opacity & Dust)

    Dust and opacity monitor for monitoring combustion processes where automatic calibration checksmore

  • Model: 4200

    The most accurate and reliable monitor can be used for dust and opacity measurements in combustion applications without automatic calibration checks and compliance.more

  • Model: 4500 MKIII

    A highly uniform LED light source is used to minimize sensitivity to optical misalignment. The prism rear reflector reduces thermal drift, resulting in a minimum detection limit. Together with Floodlight LEDS, these patented technologies minimize electronic drift, providing you with highly stable, highly accurate resultsmore
