| Two to Four Gas Portable Monitor | GX-94 Model |
 |
Features
Applications
|
| The GX-94 is a powerful and economical solution for confined space gas monitoring requirements. For one low price you receive features such as single-button autocalibration of all gases, datalogging with a lunch break mode, continuous operation for 12 straight hours on only 2 size C alkaline batteries with a dual low battery alarm (warning and fully dead), simultaneous readout of all 4 gases on an auto back-lit LCD display, a high impact RFI shielded housing, user adjustable audible and visual alarm settings, additional STEL / TWA / Ceiling alarms and readouts, as well as peak or average readouts. The GX-94 is a lot of gas monitor for its price. This compact and rugged portable instrument will monitor for % LEL levels of combustibles, oxygen deficiency, and ppm levels of hydrogen sulfide and carbon monoxide. The GX-94 is also ergonomically designed with a wide, steel-belt clip that positions the instrument’s display and visual alarms facing up at the user. There are several sampling options including the GX-94 in its standard diffusion configuration, or utilize its attachable battery driven or hand aspirated pump for a quicker response. A sturdy, waterproof carrying case is also available which custom fits the GX-94 and all of its accessories in a protective, foam padding. UL Classified as intrinsically safe. |
