GX-2009 Filter Replacement & Battery Refresh

The Model GX-2009 Portable Gas Monitor is a very reliable device. However, like all gas monitors, some routine maintenance is required. In addition to routine calibration or bump testing, there are a few other maintenance related issues that need to be considered:

GX-2009 filter replacement

 

Scrubber filters
There are H2S scrubber filters used to protect the CO and LEL sensors. These filters should be replaced every six months, possibly more often in cases where the instrument sees frequent or heavy exposure to H2S or heavy hydrocarbons. There is one H2S scrubber filter for the LEL sensor, and one charcoal scrubber for the CO sensor.

Battery Refresh Cycle
The rechargeable NiMH batteries used in the GX-2009 are generally quite resistant to the “memory” effect associated with rechargeable batteries. The charger for the GX-2009 is a “smart” charger, designed to minimize the possibility of improper charging. However, over time the battery capacity may be diminished depending on how the unit is used and charged. It is recommended that a refresh cycle be performed every six months, or when battery capacity seems to be diminished.GX-2009 Battery Refresh
Please refer to the GX-2009 Operator’s Manual or Training Video for filter replacement and battery Refresh procedures.
