Item Description:
For sale is a Forensics Detectors FD-4X 4-Gas Meter in open box condition. This unit is unused and has been inspected, complete with all original accessories and packaging. It's built for confined space work, simultaneously monitoring oxygen, carbon monoxide, hydrogen sulfide, and combustible gases (LEL) using high-quality nano sensors, with detection error under 5% and a response time of less than 30 seconds. It arrives factory-calibrated with a certified calibration certificate, and zero/span calibration options let you keep it accurate over time. Whether you're entering tanks, vessels, silos, tunnels, or working in maritime, oil and gas, construction, or wastewater environments, this meter provides the essential 4-gas monitoring needed for safe confined space entry. Opened only to verify contents — no usage performed. A reliable, purpose-built safety tool for anyone working in or around confined spaces.
