Measures Noise
December 1st 2005 The CR:261 Class 1 integrating sound level meter from Cirrus Research is a suitable noise measurement tool for users who need a Class 1 (Type 1) instrument that is simple to operate and that can be used for compliance with the latest Noise at Work Regulations.
Providing basic noise level parameters, sound level , Leq, Lmax, Lmin and Lpeak(C), the instrument can be used for occupational noise measurements and for basic noise level testing.
It meets the latest standards for sound level meters - IEC 61672-1:2002 - as well as the EN and BS EN equivalents, so will be compatible with regulations, guidelines or standards for many years.
The basic instrument can be upgraded to add data logging and PC download, at which point it can be used with Deaf Defier3 software to produce graphs, reports and export data. More articles from Cirrus Research plc: |
