Williams AV Hearing Loop Field Strength Meter

The Hearing (Induction) Loop Field Strength Meter is a tool used for evaluating the performance of an induction (hearing) loop system during installation and maintenance. With easy-to-use controls, it provides dB readings that help loop installers and users calibrate and monitor magnetic loop signals. It gauges the RMS signal energy, checking the loop's audio frequency to ensure it meets the worldwide IEC 60118-4 standard.

Williams AV builds for install: the transmitters rack, the receivers charge in bays rather than one at a time, and the earphones and neckloops are replaceable parts rather than a sealed accessory. Ordered as part number PLM FSMP. Published dimensions, power and warranty are in the specifications tab.
