1 NR = not recommended (does not register)
? = measurable but no data exist
Confirmed Value = “+” means actual gas has been used to verify RF, “blank” means it is an empirical estimate
IP = is the gases ionization potential (only gases < 10.6eV will respond to sensor)
TWA/Time Weighted Average = generally accepted limit for safe 8 hour exposure (in ppm)
ne = None Established
