The CR:800A series sound level meters are now available with PTB approval. The PTB laboratories are one of the most prestigious in Europe and their Type Approval assures a design that genuinely meets the exacting acoustic standards.

Such approval is essential for many noise measurement applications in Germany and other European countries. Although not essential in other regions it gives that extra confidence in the accuracy of the measurements.
