Sound Pressure
RANGE
from 10 dB to 160 dB
- Sound pressure measuring devices,
- noise dose measuring devices – dose meters,
- sound pressure calibrators,
- vibration measuring devices.
WE PERFORM
- Acoustic calibrations in accordance with requirements of standards IEC 60651 and IEC 60804 in frequency range from 31,5 Hz to 12,5 kHz with best measuring capability 0,2 dB (depends on the microphone);
- best measuring capability (BMC) applies for instruments, whose microphones have all characteristics recognized.
- electrical calibration of sound pressure measuring devices is performed in the entire dynamic (from 40 dB to 154 dB) and frequency (from 31,5 Hz to 20 kHz) range with measuring capability 0,1 dB.
- acoustic and electric calibration of noise dose measuring devices is performed in accordance with requirements of standard IEC 61252 with best measuring capability 0,2 dB for acoustic part and 0,1 dB for electric part of noise dose measuring device.
- calibration of sound pressure calibrators (pistonphone) is performed in accordance with requirements of standard IEC 60942 at frequencies 250 Hz and 1000 Hz and levels 94 dB, 104 dB, 114 dB and 124 dB with best measuring capability 0,08 dB.
SERVICE
- We perform service and adjustment of measuring instruments of all types in the field of acoustic quantities – sound pressure and vibration measuring devices.
WHY PERFORM CALIBRATION
- Accuracy of measuring devices is not stable time-wise,
- changes in temperature, humidity, air pressure and other adverse factors can affect the accuracy of measurement, as well as operator’s work,
- regularly perform calibrations to ensure accurate and precise operation of the measuring device.
Certificate, which you are provided with after each calibration, ensure measuring traceability of measuring devices with establishment and maintenance of quality systems (ISO certification), laboratory accreditation and is in accordance with requirements GMP, GLP and GCP.
CALIBRATION PERIOD
Calibration period is set in accordance with standards or recommendations for ensuring quality of measuring equipment SIST ISO 10012, ILAC-G24 / OIML D10.
