Air Check Carbonyl Sulfide Monitor

Item #: 99156


Product Summary

The AirCheck Carbonyl Sulfide (COS) Monitor is a compact extractive gas sampling system designed for the continuous detection and measurement of toxic gas leaks. It is capable of sampling over distances of up to 100 feet (33 meters). The COS monitor is a single point monitoring system built into a general-purpose, polycarbonate housing that may be wall-mounted. It’s designed to require as little space for installation as possible.

Stock Available
  • Detectable limits COS up to 100ppm
  • Detects low range TLVs
  • Sampling pump with monitoring capabilities up to 100ft
  • 2-year warranty
  • User Selectable Dual Level Alarm and System Fault Relays
  • Digital display and 4-20mA analog output connects to PLC

The AirCheck Carbonyl Sulfide Gas Monitor is ideal for facilities that require continuous monitoring and protection of personnel around semiconductor process tools. The built-in pump allows for monitoring up to 100 feet away and is perfect for use in valve manifold boxes or spaces that are not easily accessible. This monitor is well suited for environments such as semiconductor clean rooms where toxic gas is present.
