We’re pleased to announce that the Class 1 Optimus Green and Class 1 Optimus Red Sound Level Meters have passed the latest round of Type Approval Tests and have been certified as meeting the latest version of the sound level meter standard, IEC 61672-1:2013 (and the corresponding NF EN 61672-1:2014 publication).
The instruments have been tested and certified by the LNE, the French National Standards Laboratory, and the new approval extends the previous certification whilst adding the CR:161D and CR:171C variants of the Optimus Red and Green ranges respectively.
The Class 1 Optimus Green and Optimus Red sound level meters had previously been Type Approved by the LNE to the previous version of the IEC 61672 standard (IEC 61672-1:2002) and the corresponding NF EN 61672-1:2003 version in June 2013.
The Optimus instruments also carry Type Approval from the PTB in Germany and Applus+ in Spain. A full list of the approvals carried by the Cirrus Research products can be found on this page.
This new approval is to the latest version of the sound level meter standard and continues to demonstrate that the Optimus sound level meters meet the very highest levels of accuracy and precision.
