For sale is a Lot Of 2 Biosystems Inc. PhD Ultra Multi Gas Detector Kits. This is being sold FOR PARTS OR NOT WORKING as they have been UNTESTED! The chargers do appear to work. I am not sure if the batteries or the units work. One of the units appears to have a busted screen. The foam inside the carrying cases is in poor condition. Could use cleaning. Please take a close look at the pictures. What you see is what you get AS IS! Shipping is for the lower 48 states. Other shipping will be calculated. I ship Monday-Thursday, meaning that If you purchase an item(s) on Friday-Sunday your item(s) will ship out on Monday. If you have any other questions please feel free to message me. Thanks!
