About Portable & Personal Gas Monitors

These gas detectors and monitors are used for the detection of flammable gases, oxygen depletion, and an extensive range of toxic gases meeting the safety monitoring requirements of a broad range of different industries. When dangerous levels of gas vapours are detected, alarms sound and flashing lights appear.

These units are fully portable, usually worn on clothing or clipped on a belt. However, the optimal location is as close as possible to the primary entry points for toxins to enter the body - the nose and the mouth.

Typically utilised when entering tight spaces, dispatching emergency personnel into potentially explosive environments, locating gas leaks, or performing hot work in potentially hazardous areas. The detectors shield their users from a wide range of potentially dangerous gases and respiratory poisons, all of which behave differently.
