Field strength meter with analogue display.

Univox® FSM Basic is a calibrated precision measurement device, designed for measuring the performance of Audio Frequency Induction Loop Systems (AFILS). The meter enables easy and straight-forward assessment of background noise, field strength and frequency response of the system to comply with the requirements of IEC 60118-4.

Two different frequency response characteristics are provided: ‘NORMAL’ which is a restricted response, similar to that of a hearing aid, and ‘FLAT’ which is a wide, flat response, similar to that of an equalized induction loop receiver for wide-band communication.



  • PPM meter responding to program peaks
  • Real time verification of sufficient field strength for good speech clarity
  • The monitor audio output is active on all range and filter combinations.
  • Operates over a very wide range of 54dB in two stages
  • Two measurement filter (tone) responses
  • Low battery indication
  • Volume control
  • High quality components for low noise
  • The meter is calibrated, traceable to International Standards
