AFF25-3

Display/Recorder/Integrating sound level meter - Embedded Web Server - IP Connection


AFF25-3 is a sound pressure logger display for simple and effective visualization of ambient sound pressure levels (bars, discotheques, concert halls, party halls).

In order to provide reliable support for sound level monitoring, the AFFseries-3 have the distinction of being able to change color according to pre-defined thresholds and over a wide range of colors.

It is both in compliance with the NF S31-122-1 standard of January 2017 and Article R.1336-1-II -3° of Decree N°2017-1244 of August 7, 2017 on the prevention of related risks of sounds amplified for the part concerning the display of sound levels.

It is also in conformity with article R.1336-1-II-2° of the same decree and with the norm NF S31-122-1 for the recording of the sound levels.

The Integrating Sound Level Meter complies with Class 2 according to IEC61672-1 of March 2014.


• Display on three independent programmable displays in A or C weighting in Leq1s, 1min, 5min, 10min, 15min, 60min as well as in LpCmax 1min. Each display is configurable in basic color and according to overruns.
• Continuous recording of sound levels in A and C weighted decibels, in the form LAeq1min, 5min, 10min, 15min, 60min and LCeq1min, 5min, 10min, 15min, 60min sliding average in 1min increments, as well as LpC max1mn and LAFmax1min. The internal memory is dimensioned to store these values 24 hours a day and 7 days a week, for 6 months.
• A 9-level trend predictive indicator, based on the 1 minute Leq, makes it possible to better manage sound management and to act smoothly and with anticipation to avoid overtaking Leq 10min, 15min or 60min.
• Two relay outputs GPO1 and GPO2 (on RJ45) allow the triggering of an alarm or an external signaling.
Choice for each GPO of weighting A or C and Leq1s, 1min, 10min or 15min.
• The consultation and the programming are carried out by the LAN port(IP).
• Integration of an embedded web server, allowing the configuration, the consultation in real time of the sound levels as well as the downloading of the recording memory of these. The link under IP works with any OS, any browser and especially without downloading specific software.
• Operating alone or in a network.
• Supplied with a swivel bracket to allow the ideal orientation.
• 12V power supply provided.
