About This Product

The Aerosol Monitor LB9140 is used to measure airborne alpha/beta particles under the influence of natural radiation (radon) and a fluctuating gamma background. The display is equipped with a self-monitoring feature that continuously monitors display and alarm conditions. The system has the advantages of being quiet, vibration-free, maintenance-free and having a long service life.

■Main configuration

・Filter tape unit LB 9128μ: Enables rapid measurement of radioactive α/β particles using a Si-CAM detector. ・Alpha Beta Detector: Measures directly in the placed area and realizes a real-time monitoring system. - Cassette: Made of aluminum with protection class IP68, it consists of a dust collection unit, filter supply, and take-up spool, and the plexiglass front door allows visual confirmation of the filter supply. Filter feed is driven by a stepping motor unit and can be fed continuously at user-selected speeds (5/10/12.5/15 mm/h). It is also possible to step through the filter at user-selected time intervals.

■Summary

・Direct measurement of artificial α/β radiation that can be corrected for radon products using ABPD & AED correction methods ・Portable monitor with small footprint ・Si-CAM detector unit (600 mm²) that can measure α/β individually and simultaneously

■Features

- Continuous filter operation speed is variable in 4 steps from 5 to 15 mm/h (warning before paper ends) ・Step filter operation possible (optional) ・Low-noise, low-maintenance pump unit with fault monitoring (flow meter optional)

■Self-check & alarm

・Monitoring of pump function ・Monitoring of filter tape ・Detector failure thresholds α and β (γ if installed) ・Pre-alarm threshold α and β ・Alarm threshold α or β ・Lamp test
