Personal gas monitoring equipment

[Rob]

Does anyone have a procedure for working/operating personal gas monitoring equipment after -20C. The manufacturer says don't use the equipment after -20C but thats not possible in Alberta's climate. Anybody have any suggestions?

An idea might be to use cholormetric tubes. simply they are a glass vile which contains a powder that will change colour when exposed to certain gasses. they can be purchasd for any type of gas. the down side is there will be no alarm.

Thanks for the post - But most personal monitors are good to -20C so I wonder why they would call the example you sent "Cold Climate". We use the MicroAlert by BW and it is good to -20C. I wonder what can be used at -30C or colder or if somebody has a cold climate procedure or something.
