Environmental Noise Monitoring 6224, 6226
6224 (Class 1) and 6226 (Class 2) Integrating Sound Level 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.These 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
These can be used for
* Noise at Work Measurements
* Environmental Monitoring
* Multi-purpose Measurement viz. Leq, Lmax, LE.
| 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 datapoints Back-lit LCD display |
