* Channel selections can be selected at time of order in a range from 0.3 μ to 25 μ. However 0.3 μ and 25 μ cannot be configured together.
** Battery life is estimated with these conditions: The 1.77 cfm unit sampling for 20 minutes (1 m3) sample, print record, a 5-minute hold time (simulating move to new location), then repeat this cycle. Backlight sleep time is set at 2 minutes. The 1.0 cfm unit, sample time is set at one minute, print record, a 1-minute hold time (simulating continuous sampling mode), then repeat this cycle. Backlight would remain on at all times.
