Product Name: PGM102 Portable Gas Monitor

Product Description

The PGM102 is a self-contained mobile monitoring/sample collection station for radioactive noble gases, particulates, iodines and tritium in a gaseous sample media. The inlet gas sample passes first through a dual charcoal cartridge and a 0.3 micron filter paper which removes iodines and particulates from the sample. It then passes through an unshielded 8.3 L counting chamber with a dual phosphor scintillation detector (plastic scintillator and BGO crystal). The BGO crystal provides a gamma activity signal with a slower rise time pulse, thus allowing it to be identified by the preamplifier and used as a compensating signal for the gamma background.

CANBERRA’s full featured ADM606M Control and Display Unit processes the detector (logic) signals from the preamplifier and data from other sensors to provide live time digital display and alarm functions. It also functions as the control unit and display for the sample collection systems.

The PGM102 gas monitoring station provides independent sampling systems to collect quantitative samples for laboratory analysis for tritium, iodine, particulate, and noble gas activity. Air sample flow rates are controlled and measured by mass flow rate controllers for both the monitoring and sample collection channels to allow calculation of activity concentration in the gaseous media.

Functionally, the PGM102 comprises several standard CANBERRA instrument modules interconnected into a stand-alone system on a rugged handcart frame. Each monitoring and sampling subsystem includes the required isolation valves, flow indicators, quick connect fittings, and connecting hoses to provide jobsite convenience without sacrificing the laboratory level sensitivity and accuracy of the initial instruments. Workers in protective clothing can readily move the handcart station to a selected site, connect the electrical and pneumatic systems, and activate the monitoring station functions in a fraction of the time required to set up separate monitoring and sampling systems.

The PGM102 is designed for use at locations where ac electrical power and a source of pressure or vacuum is present for transport of the sample through the monitoring system. An external vacuum pumping system may be connected to the air outlet connection if the inlet sample flow is not pressurized.
