Details: Best in its class, the professional series CO detector by FORENSICS. High precision for accurate measurements and robust for fieldwork, inspections, occupational safety, industrial, and environmental applications. It comes factory-calibrated. Using electrochemical sensors, the detection range is 0 - 1000 ppm within 30 seconds. Comes with advanced features such as temperature detection, adjustable alarm setting, backlight high-resolution LCD, and calibration. We also offer a built-in pump version, our model FD-600-CO CO Gas Analyzer for Inspectors.

Carbon monoxide (CO) is a toxic gas. OSHA emphasizes that carbon monoxide is a poisonous, colorless, odorless, and tasteless gas - making it very elusive. Although CO has no smell, it is often mixed with other gases that do have an odor (i.e. exhaust gas). When carbon monoxide is inhaled, your body replaces the oxygen in your red blood cells with carbon monoxide. This leads to asphyxiation, serious tissue damage, brain damage, and even death.

Included: CO gas detector, belt clip, sling, English manual, USB charging cable, calibration cover, and USA NIST calibration certificate.
