Smart Sensor AR824 MAX Sound Level Meter, 35-130dB Digital SPL Meter with Windscreen, for Sound Field Calibration and Noise Testing

Know exactly how loud your space is - before every test.

The Smart Sensor AR824 MAX is a digital sound level meter covering 35-130dB with a condenser microphone sensor. In audiology practices it is the practical companion for sound field calibration: verify speaker presentation levels before pure tone testing, and keep visual reinforcement sessions consistent visit after visit. It is equally at home checking office, classroom and industrial noise levels.

The large LCD shows readings at a glance with MAX hold, while FAST and SLOW response modes and A/C frequency weighting adapt the meter to different measurement tasks. Powered by 4x1.5V AAA batteries (included), it travels safely in a zip carrying case together with a windscreen foam ball that reduces wind noise for outdoor readings.
