CEL Acoustic Calibrator 350
The field calibration of Sound Level Meters is an essential procedure when carrying out any type of noise survey both before and after each measurement sequence. This ensures that instruments are providing consistently accurate readings necessary for monitoring to ensure compliance with workplace and environmental noise regulations.
Features:
Measures and logs all workplace noise parameters
28 hour battery life, fully charges in 90 minutes
Simple auto-calibration function
Run duration timers
Simultaneous ‘C’ and ‘A’ weighted measurements
Large memory capacity 180 hours
Compact, rugged (rubber overmoulded) design weighs only 71g
No cables to damage or get in the way
Applications:
Complete shift exposure measurements
Task based measurements
Measurements according to ISO9612: 2009
Selection of hearing protection
Measuring personal noise exposure
