Archives - Data logging sound level meter

The SPL25 allows both audio pressure level metering and recording. The associated sensor is either the CAP65, the CAP40 or for outdoor the CAP90.

• Recording is in peak and in average level (Leq 1min, 5min, 10min, 30min or 60min) weighting A or C.

• Real time reading allows instantaneous level display (1s integration), Leq level (1min,5min,10min,30min or 60min) and a Leq variation graph. Historical exportation is in text, CSV or HTML format.

• The internal memory is dimensioned to store the values 24 hours a day and 7 days a week,for 6 months.

• The measuring range is 61dB to 123dB for average level and 71dB to 133dB for peak level.

• For environmental measures select sensors CAP40B or CAP90B with a measurement range of 41dB to 123dB in an average level and 51dB to 103dB for the peak level.

• Reading and settings use LAN port (IP network). It is possible to connect several SPL25 on the same network, allowing audio level analysis in various places, like for large rooms, or stadium. Each SPL25 will have its own IP adress.

• A very important feature is the embedded web server, allowing configuration and reading the SPL level, using any web browser, under any OS. It does not requires a specific software.

• Two static relays output (Opto-Mos) allow external equipment switching. These outputs allow to switch on a light (requires an interface) or audio level control.

• USB port is used for internal software update.

• USB Host for connecting a USB stick for collecting history.

• A 12V DC power is supplied with the equipment.
