XENON MONITOR

Model # FM-5XE([fig] ([fig] FM-5XE) FEATURES:

* LOG SCALE.NO RANGE SWITCHING

* WRITTEN RECORD

* SETTABLE ALARM

* COMPLETELY MODULAR, STANDARD FM-5

* CAN DRAW FROM USE AREA, DUCT, ETC.

APPLICATION: The FM-5XE Monitor is becoming a standard safety
instrument at all facilities where Xe-133 (m) is used.


DESCRIPTION: Model FM-5XE Xenon Monitor determines xenon
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 three 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 meter, it
furnishes permanent record in the form of a strip chart.
An alarm is included which produces a red flashing light
and/or 2,000 Hz (beep) should the preset level be exceeded.
The meter and strip chart record are in log form so that
they cover a dynamic range of 10,000 - 1 with no range switching.
