ARGON/NOBLE GAS MONITOR Model # FM-7XE-M2 FM-7XE-M3 FEATURES: * NEW, IMPROVED DIGITAL MONITOR USER FRIENDLY SIX-DIGIT READOUT * MEASURES: Ar, Kr, Xe, Rn * AIRBORNE CONCENTRATION & TOTAL DOSE IN MPC (OR ANY UNITS) * ADJUSTABLE AIR FLOW * SETTABLE ALARM * RS-232 COMPUTER AND/OR DATA LOGGER INTERFACE * OPTIONAL PRINTER FOR HARD COPY APPLICATION: The FM-7XE-M2 Monitor is fast becoming the first choice for Noble Gas users in facilities all over the world. FM-7XE-M2 DESCRIPTION: Model FM-7XE-M2 Argon/Noble Gas Monitor determines Argon and Noble Gas content of air by drawing the air through a gas chamber which is under constant surveillance by a radiation detector. It is normally supplied with a six foot outlet and inlet hose so that it may draw air from the use area, duct, etc. In addition to showing the xenon content on the digital meter, it furnishes permanent record in the form of an optional digital printer with date & time stamp. An alarm is included which produces a red flashing light and/or 2,000 Hz (beep) should the preset level be exceeded.
