Certified Pre-Owned Gas Detectors

Get the World’s Most Reliable Gas Monitors at an Exceptional Value

Don't settle for just any used gas detectors. Every Industrial Scientific CPO gas monitor gives you virtually all of the durability, reliability, and dependable performance of a brand-new gas monitor. You can be assured that the gas detector you receive has been scrutinized to the exacting standards you would expect from Industrial Scientific.

Only gas detectors that pass a rigorous multi-point inspection, including intrinsic safety approvals, are included in this program. Our CPO monitors are certified once they pass a factory inspection checklist to ensure that all components perform as originally designed, and then are backed by a one-year warranty.
