The MultiRAE Plus combines a PID (Photoionization Detector) with the standard four gases of a confined space monitor (O2, LEL, and two toxic gas sensors) in one compact monitor with sampling pump. The MultiRAE Plus is quickly and easily changed from a sophisticated technician instrument to a simple text-only monitor. The same monitor can be used as a personal monitor, a hand-held sniffer, or as a continuous operational area monitor. The detector can be made wireless with the use of RAELink2.
