Overview of the portable single gas monitors:

There are two different models in the series, the GX-8000 portable single gas monitors (LEL & O2) detects the oxygen in the air or LEL which detects dangerous combustible gases like methane, isobutane and hydrogen.

LSD Display

The large, LCD display, shows a digital value of the component gas concentrations up to 5 by simultaneous display, and performs more reliability to confirm the concentration. In loud environments the high brightness LED lamps arranged in three directions alarms, the workers in a visible way.

IP rating

These portable single gas monitors (LEL & O2) features a waterproof and dustproof design with IP 67 rating for which the over-mould body is impact resistant and RFI shielded. Consequently, the GX-8000 portable single gas monitors (LEL & O2) offer full protection while minimising large fleets because of it’s functionality.
