Loopworks Measure iOS app

Loopworks Measure iOS App

Loopworks™ is a suite of online and App based tools and resources that enables customers to specify and design hearing loop systems.

Loopworks Measure combines an iOS phone or tablet App that utilises a self-calibrating receiver. Together they become the most accurate, dedicated field strength meter (FSM) currently available. The Measure App and R1 Receiver are supported by the Loopworks online database and reporting tools. The App can also be connected to any network enabled Ampetronic loop amplifier, to automatically control test signals and get direct access to key settings.

Designed for iOS 11 and up. The Loopworks Measure App will not function without the Loopworks Measure Receiver Hardware

The Loopworks system helps to measure the magnetic field produced by a hearing loop / induction loop system to either assess whether a system is functional or to measure it against the IEC 60118-4 Standard for hearing loop performance.

Once users have created and signed in to their Loopworks account, the App can synchronise data with the Loopworks online portal. This makes it possible for users to view, analyse and share their results online. The portal can also be uses to create test and certification reports. Support is available from our loop experts via telephone or Live Chat.
