Loop Tester/Field Strength Meter

The Opus Technologies Induction Loop Receiver and Measuring Kit OP-LRM combines an OP-LR receiver/measurer with OP-778 headphones, providing a compact solution for listening to and checking induction loop systems. It enables installers and maintenance teams to monitor transmitted audio through headphones and view magnetic field strength indications on the receiver.

The receiver features yellow, green and red LED indicators for magnetic field strength, alongside a standard 3.5 mm stereo headphone output. The included headphones allow users to listen to the loop signal when carrying out installation checks or routine system inspections.

Powered by a lithium-ion battery with Micro USB charging, the receiver measures just 35 × 20 × 75 mm and weighs 34 g including its battery. Its compact size makes it convenient to carry between locations when checking an induction loop installation.
