Item:LOOPWORKS-R1 Price:$395.00MSRP

The R1 Receiver is a high quality audio induction loop receiver with a vertically mounted pick up coil. Designed to be used in conjunction with the Loopworks Measure iOS App the R1 Receiver and App together become the most accurate, dedicated field strength meter (FSM) available.

Ampetronic customers can now download their Measure App FREE from the iTunes store and order their Loopworks Measure R1 Receiver field strength meter. Please note that the Loopworks Measure iOS App is currently only available through iTunes store and will only run on an iOS device; that is an iPhone, iPod Touch or an iPad device running iOS 11 or higher.

Please Note: The app supports use of the R1 with Apple lightning to 3.5mm adapters but does not currently support USB-C devices. We are working on an update to bring USB-C support to Loopworks Measure as soon as possible.
