Wireless Sound Level Meter type 1 microphone NSRTW_mk3

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.

Integrating Sound-Level Meter, records L-max, L-min and Leq levels.
Log interval adjustable from 125 ms (8 points per second) up to hours.
Individual Manufacturer's Certificate of Calibration from Convergence Instrument provided with every instrument purchased.
WiFi™ connectivity to report measured levels remotely and automatically at preset intervals.
Email alerts for sound detected over specified threshold, as well as low-battery.
Digital very sensitive MEMS microphone (30 dBA typical noise floor)
Completely sealed weatherproof enclosure designed for outdoors applications. Now includes an ePTFE membrane that seals the microphone against dust and water.
All-digital design.
Ultra-stable sensitivity (field recalibration is easily done, but seldom required)
Very low sensitivity variation due to temperature changes
Very low sensitivity to vibrations
Software function calculates global Leq and/or dose, according to ISO and OSHA methods.
Adjustable response time.
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.
All settings are stored in non-volatile memory. So the instrument will regain full functionality and WiFi connection from hard-reset or battery loss.
Compatible with Convergence Instrument's Cloud servic
