PLACID PNSRT-Mk3
Smart integrating sound level meter noise monitoring
Measurement Microphone Logger
The PNSRT-Mk3 is a MEMS based smart integrating sound level meter / datalogger complying with Class 1 accuracy.
Technology
Basics
PLACID’s smart integrating sound level meter / data logger, 3rd generation, MEMS microphone, Class 1 with build in 128 MB recording, accessible with fast USB download.
Running on an internal battery it can record sound levels for 1 weeks, if connected to an external USB charger or small A4 sized solar panel it can record for months.
As all PLACID microphones, the PNSRT-Mk3 comes with an individually calibration certificate.
Connectivity
The PNSRT-Mk3 is a complete set, ready to use as sound level meter and/or data logger.
Uses
Sound level and acoustic dose measurements and recording, monitoring of safe working conditions, activity detection and logging, noise impact studies (long term measurements), weatherproof ready to be used outdoors (no cabinet needed).
Daily usage
PLACID recommends regular calibration however MEMS microphones are extremely stable.
Individual calibration
All PLACID measurement microphones set are being calibrated in a controlled laboratory environment using traceable calibration equipment complying with ISO17025 standards.
PLACID Traceable Calibration is performed by our qualified staff and under controlled conditions according to the procedures and standards such as ISO17025.
Quality
All PLACID microphones are made of high-quality materials that will ensure long stability and durability.
PLACID offers 2 years warranty against defective materials and workmanship.
FEATURES
- Type I precision
- A, C and Z weighting curves.
- Integrating Sound-Level Meter, records L-max, L- min and Leq level
- Log interval adjustable from 125 ms (8 points per second) up to ho
- Individual Manufacturer’s Certificate of Calibration from Convergence Instrument provided with every instrument purchased.
- Digital very sensitive MEMS microphone (30dBA typical noise floor)
- Completely sealed weatherproof enclosure designed for outdoors application 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
- Adjustable response time
- Preprogrammed recording start date/tim
- 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 on
- Works standalone, or USB connect
- 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 memo So the instrument will regain full functionality from hard-reset or battery loss.
