SPL25-3

Data logging sound level meter
Standard NF S31-122-1-2017


SPL25-3 allows both the measurement and recording of sound levels. The associated sensor is either the CAP65, the CAP40/50 or for outdoor capture the CAP90.

It complies with the NF S31-122-1 standard of January 2017 for recording sound levels. The Integrating Sound Level Meter conforms to Class 2 according to IEC61672-1 of March 2014.

• 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.
• 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 configuration and real-time consultation of sound levels. The link in IP form works with any OS, any browser and especially without having to download any specific software.
• Operation alone or in a network. It is thus possible to connect several SPL25-3s on the same network to allow sound analysis at several points, in the case of a stadium or a large hall for example.
• A USB Host connector allowing the connection of a USB key for collecting the history.
• A 12-volt mains power supply is provided with the equipment.
