The Α-Β-particulates monitor LB 150 D-R uses a fixed filter and is a true real time monitor while collection, detection and evaluation are done.
The Α-Β-particulates monitor LB 150 D-R uses a fixed filter and is a true real time monitor while collection, detection and evaluation are done simultaneously.
The very high sampling rate of 40 m³/h ensures a representative sampling for both stack monitoring with isokinetic extraction as well as room or workplace air monitoring.

Features of LB 150 D-R
- Simultaneous Measurement of artificial Α- and Β-particulates
- Compensation and measurement of natural radioactivity (Rn/Tn daughters)
- 3-fold large surface proportional counter with high Α- and Β-efficiency
- Prompt measurement of the activity deposited on the collection unit
- High sample airflow for representative sampling
- Collection of airborne particulates on a 200 mm Ø glass fiber filter
- Continuous measurement and alarm threshold monitoring while sampling
- Isokinetic airflow, known particulates loss factors taken into account
- Measuring principle independent of particulates energy
- Independent of pressure or temperature fluctuations, minor influence of filter loading
- Independent of Radon/Thoron ratio
- Minor influence equilibrium state of the Radon/Thoron progeny (depends on in situ conditions – geological, meteorological)
- Data collection and evaluation unit LB 9000 with ABPD/AERD application program to set parameters and visualize Measurement results. Utility programs for service and maintenance: calibration, plateau take-up, background measurement, recurrent testing, etc.
