GMI PS241 Gas Detector Gas Personal Safety Monitor Not Working. Condition is "For parts or not working" because we do not have a charger and we are unable to test. There are some that won’t turn on and may just need a charge. We do not have a charger... they may be discharged or not work.... not sure.  We have a bunch listed that turn on however we also do not have a charger for those otherwise we would have tested these.
