Hangzhou Aihua AWA5661-W Sound Level Meter
Product details
With the development of technologies such as the Internet of Things and smartphones, acoustic measurement equipment should also move towards intelligence, networking, and IoT.AWA5661-W Sound Level MeterThe measured noise data is sent out through WIFI, and the receiving devices can be selected from smartphones, tablets, laptops, and desktops. The powerful processing capabilities of these devices can be used for calculation and analysis, with powerful functions and flexible matching. The instrument can be used in conjunction with PC or mobile software (Noise Assistant APP) to achieve functions such as total value analysis, statistics, and spectrum analysis.
