5.4.4. Sample area connections
NOTE
The buyer is responsible for deciding which areas and gases to monitor and the
exact location of the sampling points in gas cabinets, storage rooms, valve boxes,
exhaust ducts, exhaust hoods, breathing zones, etc. Honeywell does not
determine and cannot advise the exact point to sample for hazardous gases. The
buyer, the equipment manufacturer, or a third-party consultant must make such
decisions.

Points and gases monitored
The ACM 150 monitor is designed for and intended to detect occasional leaks of
hazardous gases at levels within its detection range. The following conditions may harm
the ACM 150 monitor and may violate the warranty terms:
• Continuous oxidizing or corrosive gases at one or more sample points at levels
exceeding 10 PPM, mainly if the air is humid.
• High PPM level leaks that saturate the ACM 150 monitor with oxidizing or corrosive
vapors.
• Liquids (water, solvents, or oil) present in the sampled air that enter the ACM 150
monitor via the sample tubing.
• Flammable gases above explosive levels that might increase the risk of fire inside the
ACM 150 monitor.
The ACM 150 monitor is not suited for monitoring samples that contain high levels of
corrosive and condensable gases, such as the exhaust from treatment systems.
