MultiRAE PLUS One to Five Gas
Monitor with VOC Detection
Build
your own personal gas monitor!
Designed
as a "building block" system, the MultiRAE can be configured
from a simple, inexpensive Oxygen/LEL monitor all the way to an affordable
five gas monitor for total protection in toxic environments. The
MultiRAE is easily reconfigured and upgraded to meet your changing needs.
MultiRAE¡¯s versatility allows it to replace a wide range of monitors,
saving training and maintenance costs. The MultiRAE is quickly and easily
changed from a sophisticated technician instrument to a simple text or
display only monitor. The same monitor can be used as personal monitor, a
hand-held sniffer, or area monitor for:
- industrial hygiene work
- emergency response
- confined space entry
Four Gases Are Less Than Total Protection
Most confined space monitors provide less than total protection because they miss many toxic vapors and gases. LEL sensors measure explosivity, not toxicity. Many Volatile Organic Compounds (VOCs) are potentially toxic at levels that are well below the sensitivity of the LEL sensors found in most multi-gas monitors. For example by the time that LEL sensors even respond to gasoline vapors the air is already toxic! The MultiRAE accurately measures low levels of VOCs without the annoyance of false alarms that are so prevalent with other "broad-band" sensors. Its patented VOC monitor, measures 0 - 2000 ppm of VOCs¡¯ while providing continuous display and alarms for worker protection. Alarms can also be set for Short Term Exposure Levels (STEL), Time Weighted Average (TWA), Peaks and Minimums. The MultiRAE displays the exact airborne VOC levels so that you do not have to guess when to put on respiratory protection. With the MultiRAE you work safer, more efficiently and more comfortably because you can go longer without respiratory protection with complete confidence you are working in clean air.
