Overview
The AMITTARI AS-156B is a multifunctional sound level meter with 0.1dB resolution and +/- 1dB Precision. This product is suitable for machine noise, vehicle noise, architectural acoustics, environment noise and electroacoustic measurement.
Features
1. With DC output of 10 mV/dB
2. Can store 30 sets of measurement data and measurement status
3. Three weighted "A"/"C"/"F" options and time weighted "fast and slow" options
4. Measurement parameters: Lp ordinary sound level measurement, Leq equivalent continuous A sound level measurement, Lmax maximum sound level measurement, LN statistical sound level measurement
5. Equipped with functions such as "alarm value setting", "output", "automatic shutdown and manual shutdown"
6. Use USB data cable output to communicate with PC
7. Provide Bluetooth data output selection
Principle
The product collects sound signals through a 12.5mm condenser microphone for measurement in the 20~ 12,500Hz Frequency range. Frequency weighting "A"/"C"/"F" and time weighting fast and slow modes are used to process sound signals, which can measure Lp, Leq, Lmax, LN four parameters, and built-in 94dB calibrated signal to ensure measurement accuracy.
Applications
Machine noise, vehicle noise, building acoustics, environment noise, electroacoustic measurement
