The Process Photometer PAP 612 is a combined in-line extinction and scattered-light photometer (ES) for blow-by measurements (aerosol concentration determination) with double-running test sections and two wavelengths, which can operate in over- or underpressure.
The device is primarily designed for investigations of crankcase ventilation of combustion engines. Thus it should support the development and testing of filter systems. Due to its compact design, its use is conceivable on test rigs for engines, on swivelling test rigs, under lab conditions as well as for test drives in field use.
Advantages
Transmission and scattered-light measurements of 2 wavelength with high time resolution
Low uncertainty of measurement through two different measuring lengths
Compact design for the use at laboratory, engine and tilt test stands and for field use
Operation in over- and underpressure
Use for aerosols and suspensions
Windows software PAPWin for calibration, configuration and data acquisition
Applications
Detection of unwanted fluids in pipe systems for gas transport (e.g. gushes of oil or detection of condensation)
In-line characterisation and concentration monitoring of blow-by aerosols
Concentration measurements in aerosols, suspensions and emulsions
Determination of mean particle sizes of submicron aerosols
