For measurements in the range below 20 Hz, use the high-precision sound level meter NL-62 supporting measurement from 1 Hz.
The model has a help function that facilitates use in the field also without consulting the instruction manual.
The meter is waterproof (IP54 rating, excluding microphone), so sudden rain during outdoor use is not a problem.
An auto store function is standard, allowing continuous recording of measured instantaneous sound levels, time averaged sound levels etc.
Recorded data can be managed with the AS-60 data management software for environmental measurement.
