Casella Logging Sound Level Meter Type 2 with Standard Accessories

CEL-632-B2 Logging Sound Level Meter Type 2 with Standard Accessories by Casella

Noise measurements from complex sources require a complete knowledge of the variable noise climate over an extended period of time. The CEL-632 model is designed to satisfy this need by providing overall, periodic and profile time history recording to suit almost any industrial or environmental measurement requirement. A super wide 120 dB dynamic range means that the user does not need to worry about selecting scales as the meter will always be on the right range. The provision of all the popular frequency and time weightings simultaneously allow many different noise measurements to be taken by new and experienced users alike. The fullcolor, high-precision, graphic LCD enhances the user experience with this new meter.

• Storage of all results simultaneously in a huge non-volatile memory
• Direct printing to portable printer for hard copy on site

Applications

The CEL-632 will be most suitable for measurements of noise levels as they vary with time. It provides all the required parameters for comprehensive OSHA, ACGIH workplace or environmental or similar noise studies. Time history information based on the Leq and max, min levels are best suited to describe the changing noise levels that can be present in the workplace or outdoors. The CEL-632 is designed to assist in the correct interpretation of these difficult noise climates. Regular periodic recording at fixed intervals from 1 sec to 1 hour is provided using a large 1 GB onboard memory chip. The changing noise intervals are stored together with the overall time average answer such as LDN, LDEN. Results are based on 24 hour overall intervals and can be linked in the Insight software into longer runs if needed. This enables the CEL-632 to correctly record changing noise levels and enables the user to visualize how the noise levels varied during the measurement. Full data logging and the measurement of the LN% values is available in the CEL-633 top of the line model. Additionally, octave and third octave band filters in the B and C versions can provide frequency analysis of tonal noises.
