I have five VRAE PGM7800 multi-gas air monitors for sale. Four of them power on with the power cord plugged in but will need the sensors replaced (screen ... moresays the warranty is expired). The fifth one will turn on (pump will work) while plugged in but nothing shows on the screen. I believe four of them are set up for 5 gas monitors (OXY, H2S, CO, LEL, and PH3) and one is set up for 4 gas monitor (OXY, H2S, CO, LEL) These gas monitors have been sitting on the shelf for a couple years not in use, I'm not sure if the batteries will hold a charge. I would change all the battery packs and sensors before i used them in the field, all sensors can be purchased thourgh VRAE. This sale is for all five gas monitors.
