Opacity Meter Dealers (23 products available)

Single & Double Pass based Optical Instruments designed for monitoring Dust and Particulate concentrations (mg/m3) in the exhaust gas of industrial combustion or Air filtration processes, offer an ideal solution to your Emissions monitoring or Process control requirement. These continuous particulate monitors use either the standard obscuration opacity technique with zero and span checking or the innovative Dynamic Detection Principle technique which eliminates the need for zero and span checking through an immunity to drift with dirty optics.

The Land Model 4500 MkIII has reset the industry standard on compliance opacity and dust concentration measurement. Combining the unique features of three patented technologies, the 4500 MkIII achieves the highest available specification for the principal performance parameters, as defined by the internationally recognized ASTM Standard D 6216-07.

The dust concentration is measured depending upon the amount of light blocked by suspended articles in exhaust gas. Advanced techniques are effectively used to detect & compensate for errors due to ambient light as well as stationary dust giving accurate emission readings. Unique design of Swirling Chamber ensures effective cleaning of lenses.

OPAL 100 Series transmissometer systems are non-compliance monitoring systems that can provide continuous in–situ measurement of both visible (opacity %) and quantitative (mgm3) emissions. They are ideal for use as opacity monitors in package boiler, incinerator, and combustion process applications where EPA emission limits are applicable and precise combustion control is desired. They are also an invaluable tool for measurement of quantitative emissions, especially in applications where other technologies have limitations from electrostatic precipitators, variable air velocities andor large duct spans.

The DSL-340 Dust Monitor uses the innovative Dynamic Detection Principle (DDP) to measure dust, smoke and particulate concentration present in an exhaust gas flow in a duct, stack or flue. A light beam emitted from the Transceiver (TRX) passes across the duct, stack or flue to a Reflector, which returns the light beam to the TRX. Particles moving through the beam will cause fluctuations in the intensity of light received by the TRX. When calibrated against standard reference measurements, the magnitude of the signal variation relates directly to the dust, smoke and particulate concentration.   Features • In-situ measurement directly in exhaust gas flow• Innovative Dynamic Detection Principle, (DDP), measurement technique• Measurement reading as mg/m3 (when calibrated againststandard reference measurements)• Choice of interface options enabling easy integration into plant control system• Free utility software for PC based setup, control and data logging• Optional Operator Interface with different mounting configurations• IP65 rated external enclosure    

Ideal for the laboratory or plant floor, the model RT-6000 is a simple-to-use, off-line instrument that indicates relative opacity of plastic film, paper, laminates, printed packaging and other materials.  With a single pass of the light source through your material, the system measures relative light transmission on a scale of 0 to 100 Opacity Units, representing perfectly transparent to purely opaque materials, respectively.
