The Wireless Sound Level Meter Data Logger NSRTW_mk3 is the third generation of Convergence Instrument’s WiFi™ enabled smart integrating sound-level meters/dataloggers.

It includes a digital MEMS microphone, an accurate date/time clock, a non-volatile 128 Mb recording memory and wireless connectivity.

Running on battery, it can record sound pressure levels and report them through WiFi™ for a week.

Connected to an external USB charger it can record and report for months. Its very small size allows it to be attached to or embedded within the monitored equipment.
