$250 · Gas Detector GX-2003

Gas Detector GX-2003 updated Sell or TRADE…. Detects the presence of combustible gas, oxygen, carbon monoxide, hydrogen sulphide simultaneously. Can be LEL or percent (%) settings. Data logging function and more. Comes with the operations booklet, remote sample line, 12 volt car charger. Needs the oxygen sensor replaced for sure and due to the length of time it has been in storage I would think that the other sensors should be replaced as well and a re-calibration as required. Has other uses in other industries besides oil and gas. Well cared for and has been stored inside since it was last used. Don't need it any longer time to move it. Asking $250.00, obo OR I’d be willing to trade for an older OBD1 code scanning tool or OBD 2 & 1 combo code scanner? Email for more info. Thanks
