SPL25-3

Data Logging Sound Level Meter


The SPL25-3 is used to measure and record sound levels. The associated sensor is the CAP66 or CAP50, or the CAP50 with its outdoor kit for outdoor measurements.

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.
