Measuring noise really does not have to be complicated, even for the novice, and the Castle GA6224 (Class 1) and GA6226 (Class 2) Integrating Sound Level Meters are designed with this in mind.

These meters are 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 meters 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.

Noise at Work Measurements
These noise meters provide 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 meters 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.

Environmental Monitoring
Also ideally suited to environmental monitoring, these meters can measure 5 selectable percentile values and sound exposure (LE). Most environmental measurements require Leq and L90 plus possibly one or two other measurements. These can all be measured simultaneously and data-logged into its 10,000 data-point memory.

Multi-purpose Measurement
Many sound measuring tasks require the measurement of Leq (equivalent continuous level), Lmax (Maximum rms level), LE (Sound Exposure) or percentiles, and all of these can be completed using these meters with their accessories.

Operation
The Castle GA6224 (Class 1) Integrating Sound Level Meter and GA6226 (Class 2) have easy to follow menu systems and clearly marked keys, all designed to make the meter simple-to-use. The back-lit LCD display is also very clear with large figures and a quasi-analogue display bar to show the changes in sound level as they happen.
