Casella Sound Meter With Real Time Analyzer Reduces Test Times

AMHERST, NH, -- Designed for safety compliance and exposure monitoring, the Casella CEL-620B sound meter digitally measures sound level in factories, refineries, construction sites or other workplaces where noise is a concern. In addition to assuring compliance to government regulations, such as OSHA, ACGIH and NIOSH, it helps occupational hygienists in quickly identifying and eliminating noise factors.

Although priced in the mid-range class, the CEL-620B has features found in instruments costing hundreds of dollars more. At the top of the list is a wide sound range (20 to 140 dB) and real time octave band frequency analysis from 16 Hz to 16 kHz, along with a full-color LCD that presents overall noise levels in numerical and graphical formats.

The CEL-620B also has the capability to measure three broadband levels plus 11 octave bands over the whole audio range simultaneously in parallel. Based on digital signal processing, this simultaneous recording eliminates the need to go back and re-measure the noise to get the result set required for a thorough survey.

Additional features are:

A, C and Z (Linear) frequency weightings (simultaneously)

Fast, Slow and Impulse time weightings (simultaneously)

Q=3, 4 and 5 exchange rates (simultaneously)

measures instant, maximum and minimum levels

measures Leq, Lavg(DOD), Lavg(OSHA)

measures maximum and time average level in all octave bands

manual measurements using intuitive menus.

Up to 100 run results can be stored in its internal memory for later retrieval. The instrument connects to a PC using its integral high speed USB interface. Runs can be imported into standard office programs such as word processors and spreadsheets.

The CEL-620B is available in ANSI Type 1 or Type 2 versions depending on the microphone capsule fitted. It can be purchased seperately or as part of a full measurement kit with a matching acoustic calibrator and accessories.
