Do your monitors "cry wolf"?

Do your monitors "cry wolf"?

One thing all portable gas detectors have in common is alarm tones. 

One alarm tone is used to indicate gas hazards, albeit with varied frequency or volume for Low/High/TWA/STEL warnings. An alarm for carbon monoxide (CO) sounds the same as an alarm for Lower Explosive Limit (LEL), oxygen (O2), and hydrogen sulfide (H2S).

The purpose: warn users when invisible gas hazards reach “alarm worthy” levels so workers can take appropriate safety action.
