ACT-400 Acoustic Connect Terminal
CurrentFixed Class 1 noise monitoring terminal that combines the measuring electronics and microphone in one weatherproof housing, so no external microphone unit or cabinet is required. It is mains powered with a back-up battery, connects over Ethernet or a 4G modem with GPS, and pushes data to the Cadence platform or other open platforms rather than operating as a handheld meter.
