Product Overview

The AHAI3002 noise and vibration analyzer is a handheld noise analysis instrument when paired with a microphone. It can simultaneously measure the total noise value, statistics, spectrum, and sound exposure. The measurement results can be saved inside the instrument or uploaded in real-time to a computer, front-end server, or cloud server through Bluetooth, RS485/RS232 interface. Widely used for measuring equipment noise, environmental noise, and other fields

Application field

Factory inspection, manual monitoring of environmental noise, and automatic monitoring of environmental noise for mechanical equipment such as motors, pumps, fans, household appliances, compressors, generators, gearboxes, etc.
