The CEL-414 is available to meet those requirements where a precision sound level meter is required. A large easy to read liquid crystal display enables the noise levels to be viewed and the slim light weight design will appeal to new and experienced users alike. The CEL-414 can be supplied in European format with the standard 1/2" microphone capsule CEL-192/2F. This is a free field microphone allowing measurements from 20 to 140 dB to be displayed to the relevant IEC requirements. The optional CEL-192/2R capsule is a random incidence microphone fulfilling the requirements of the ANSI specifications. The CEL-414 is available as an A version with the A and Lin frequency weightings or as a C version with the A and C frequency weightings where simple hand held operation is required.
