Detectable Gases - Honeywell Vertex VC 4 User Manual

Detectable Gases

Vertex™ VC4 System Chemcassette® analyzer are continuous monitoring instrument. The initial analysis period listed in the following table varies based on the programmed alarm levels. This period is valid only after the system pulls a new
Chemcassette® window. Increasing the programmed alarm levels will decrease the initial sample period.
For accurate detection, gas must be present at sufficient levels and durations. Typical response times are shown in this table at 2 TLV, which will vary in duration depending on the target gas and alarm level settings. For high concentrations (greater
than full scale) a minimum of 4 seconds is required.
