620 Noise Meters

CEL-620-A1 Wide Range Integrating Sound Level Meter Type 1 with Standard Accessories by Casella

Many industrial measurements of complex noises require a complete knowledge of the variable noise level climate over a period of time. The CEL-620.A meter is designed to satisfy this need and to enhance it by providing the capture and display of the highest maximum level and the lowest minimum level together with the integrated time average level. A super wide 120 dB dynamic range means that the user does not need to worry about changing scales as it will always be on the right scale and the provision of all the popular frequency and time weightings allow many different measurements to be taken by new and experienced users alike. The full-color, highprecision, graphic LCD enhances the user experience with this new meter.

Key Benefits

• Wide dynamic range from 20 to 140 dB on single span
• A, C and Z simultaneous frequency weightings
• Slow, Fast and Impulse rms. time responses
• Large 240 x 320 pixel color ¼ VGA graphic display
• Easy to use menu structure
• Integrating capability for time average values
• Available in ANSI/IEC class 1 and class 2 accuracy depending on application
• Available as A version with broad band levels only
• Available as B version with 11 real time octave band filters from 16Hz to 16kHz plus broad band results
• Storage of all results simultaneously in a huge non-volatile memory
• Available as complete measurement kits with acoustic calibrator and case

Applications

For measurements of simple noise levels the instantaneous sound pressure level is often adequate. However, in many real workplace situations the noise levels are variable or changing too quickly to accurately visually estimate the average level over a representative time period. The CEL-620 is designed to assist in the correct interpretation of these difficult noise climates by providing the time average noise level with both the 3 and 5 dB exchange rates. Changing noise levels are properly integrating into the overall time average answer and displayed as the Leq (with Q=3) or the Lavg (with Q=5) exchange rates. This enables the CEL-620 to correctly assess changing noise levels and comparison of the results to the requirements of OSHA or ACGIH or NIOSH. Additional octave band filters in the B version of the CEL-620 provide for a comprehensive frequency analysis of difficult noise levels that is so important for the correct prescription of hearing protectors or other noise control applications.

For measurements of simple noise levels the instantaneous sound pressure level is often adequate. However, in many real workplace situations the noise levels are variable or changing too quickly to accurately visually estimate the average level over a representative time period. The CEL-620 is designed to assist in the correct interpretation of these difficult noise climates by providing the time average noise level with both the 3 and 5 dB exchange rates. Changing noise levels are properly integrating into the overall time average answer and displayed as the Leq (with Q=3) or the Lavg (with Q=5) exchange rates. This enables the CEL-620 to correctly assess changing noise levels and comparison of the results to the requirements of OSHA or ACGIH or NIOSH. Additional octave band filters in the B version of the CEL-620 provide for a comprehensive frequency analysis of difficult noise levels that is so important for the correct prescription of hearing protectors or other noise control applications.

CEL-620-C1-K2 Sound Level Meter Type 1 Kit with Standard Accessories Including Insight Database Software by Casella

Many industrial measurements of complex noises require a complete knowledge of the variable noise level climate over a period of time. The CEL-620.A meter is designed to satisfy this need and to enhance it by providing the capture and display of the highest maximum level and the lowest minimum level together with the integrated time average level. A super wide 120 dB dynamic range means that the user does not need to worry about changing scales as it will always be on the right scale and the provision of all the popular frequency and time weightings allow many different measurements to be taken by new and experienced users alike. The full-color, highprecision, graphic LCD enhances the user experience with this new meter.
