FEWER ERRORS
September 1st 2004 New products from Casella CEL are helping eliminate a common cause of acoustic measurement errors – range adjustments.
The 400 series of sound monitors that offer real time frequency analysis and a new software package have a single measurement range of 140dB to remove range adjustment problems. Simultaneous measurement reduces time and cost and ensures a high standard of data.
CEL-450 brings real time frequency analysis to the workplace for hearing protection assessment. CEL-490 measures all necessary statistical parameters, even in frequency modes. Both are point-and-shoot instruments. More articles from Casella Measurement: |
