Figure 1: FM-5XE

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.
