Product Description

Castle Sound Level Meters
Specification for Castle 6224 (Class 1)

Measuring noise really does not have to be complicated, even for the novice, and the Castle 6224 (Class 1) Integrating sound level meter is designed with this in mind.
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.

Noise at Work Measurements

The Castle 6224 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.

Environmental Monitoring

Also ideally suited to environmental monitoring, the Castle 6224 can measure 5 select- able percentile values and sound exposure (LE). Most environmental measurements re- quire Leq and L90 plus possibly one or two other measurements. These can all be measured simultaneously with the Castle 6224 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 the Castle 6224 with its accessories.

Operation

The Castle 6224 (Class 1) Integrating Sound Level Meter has an easy to follow menu system 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.

Features

  • Equivalent continuous level (Leq)
  • 5 user selectable percentile values (Ln)
  • Wide Linearity range of 90dB
  • RS232 for data output to optional software
  • Memory storage for 10,000 data-points
  • Back-lit LCD display
