When calibrated from a dry gas cylinder, multiply the reading by the CF to obtain
the true value.

Not necessarily the maximum allowable concentration.
** Methane above 1% by volume reduces the PID response, but has no effect on tube
capacity. Butane and higher hydrocarbons reduce tube capacity
.
# Methyl bromide can be measured using a 10.6 eV lamp and a 60 sec. sampling time at
room temperature. Adjust time at other temperatures proportionately.
Note:
Unused tubes contain no hazardous components but may adsorb toxic compounds
from the environment.
