The NM102 is an excellent meter to have handy in your toolbox. It measures both "A" and "C" frequency weightings and has "Fast" and "Slow" time response. It has been designed to be very quick and easy to use, even in low light levels due to its back-lit LCD screen.

• Simple noise survey
• Checking alarms

Due to its "auto-ranging" feature, there is no need to select the correct measurement range before starting use, the meter does it for you.

Some applications (such as occupational noise measurements) demand the use of a calibrated Type 2 meter. In this case please take a look at the CEL240 Type 2 Sound Level Meter.
