Class 2 Risk Assessment / Environmental System

GA6226 (Class 2) Industrial / Environmental Logging Sound Level Meter c/w Calibrator (Single level, Class 2) and Data management software and interface cable for use with GA6226

 
The in-depth combination risk assessment package for larger applications.
  • Enhanced data analysis and manipulation
  • Portable and simple to use
The meter is ideally equipped for carrying out Noise at Work Risk Assessments, as well as the majority of environmental survey work. The range of parameters measured, the wide measuring capability of the meter and the ease of use, mean that this equipment is suitable for anything from aircraft noise to lawnmower design, and from construction sites to laboratories. Castle GA6226 provides the essential measurements required by the Control of Noise at Work Regulations 2006, including Leq (equivalent continuous level) in A and C weightings, and Cpeak. The meter can data-log any of these parameters in up to 10,000 data-memories, making it more than powerful enough for the task in hand.
