This sound level meter and calibrator combination have been
designed to be very quick and easy to use. The hard carrying
case protects the meter and calibrator but we also include
the soft case so that the meter alone can be carried around
without getting damaged.
The Sound Level Meter
The sound level meter that is included in the kit has a high specification,
including "A" and "C" weighting, Fast and Slow
time response and Min/Max Hold. The large display is easy to read
and is fitted with a backlight for use in poor light conditions.
Please visit the Low Cost Sound Meter page
for more information on the sound meter itself.
The Sound Level Calibrator
The NM100 is a Class 2 Dual Level Calibrator, operating
at 94 and 114 dB, 1 kHz.
Before making a measurement, the calibrator is placed over
the microphone and switched on to 94 dB(A). Any adjustments
can be made automatically by simply pressing two buttons
on the sound level meter. The meter calibrates itself.
The calibrator is then removed from the microphone and switched
off.
