CEL-620 Wide Range Integrating Real Time Analyzer
The CEL-620 is an advanced sound level meter designed to appeal to those users looking to do basic noise studies in industrial noise situations or to investigate specific noisy products with a view to controlling the noise output to meet mandated limits. It is available to satisfy both the ANSI/IEC type 1 and Type 2 accuracy classifications by the choice of the appropriate microphone capsule. Both of the standard half inch microphones give the CEL-620 series a single wide measurement range from 20 to 140 dB without the need to change ranges.
Included in a CEL-620 instrument:
CEL-620 Wide range integrating sound level meter includes a set of 3 x AA batteries for up to 10 hours use, a wrist strap and a USB connection cable to computer. A calibration and conformance certificate is provided for all meters in the series.
Included in a CEL-620 instrument kit:
The basic CEL-620/K1 sound level meter kit includes the required meter (CEL-620A, CEL-620B or CEL-620C meter and microphone) plus a matching acoustic calibrator in a small foam lined kit case. Download of stored results would normally be done using standard office programs such as Excel.
