 NSRTW_mk3 includes the following features:

  • Type I precision
  • A, C and Z weighting curves.
  • IntegratingSound-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.
  • Open TCP/IP protocol, allows the customer to control the instrument remotely through a custom application.
  • 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 WiFiconnection from hard-reset or battery loss.
  • Compatible with Convergence Instrument’s Cloud service.
  • Sound level and acoustic dose measurement and recording.
  • Monitoring of safe working conditions.
  • 24/7 noise monitoring on construction sites.
  • Email Alerts when the noise is too loud.
  • Activity detection and logging.
  • Long-term measurement and recording of acoustic levels for environmental impact studies.
  • Specially designed for long-term outdoors applications.
