Description


The NSRTW_mk3 is a wireless sound level meter datalogger with a dust-protected type 1 digital MEMS microphone, an accurate date/time clock, a non-volatile 128 Mb recording memory and wireless connectivity with fast USB and WiFi download.

Product Description
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.

Every Wireless Sound Level Meter Data Logger NSRTW mk3 purchased is provided with an Individual Manufacturer's Certificate of Calibration from Convergence Instruments. This all-digital design includes the A, C and Z weighting curves. It is enclosed in a completely weatherproof casing which is designed for indoors and outdoors applications.. Its highly sensitive Type 1 MEMS microphone has a noise floor of 30 dB-A, and is ultra stable with time and temperature variations. The software includes an oscilloscope and spectrum analyzer features, as well as email alarms.

Over The Air Reconfiguration through the cloud.

Mounting Base and Tripod Adapter are included.

Preprogrammed recording start date/time.
Integrated oscilloscope function that can show the acoustic signal in real time.
Integrated spectral analyzer function that can show the spectrum (or 3rd-octave bands) in real time.
Can be used as a high-quality USB digital microphone
Allows the observation of recorded levels while the recording is ongoing.
Works standalone, or USB connected.
Long life internal rechargeable battery that recharges from USB and most USB chargers.
Can be field-calibrated.
Observes and records 100% of the acoustic signal (no missed samples).
Editable individual custom ID for easier instrument management.
