Sound Level Meter CEL-620A/2/K1
Sound Level Meter CEL-620A/2/K1
Internal memory, high-resolution TFT color display, real-time analysis of octave bands from 16Hz ... 16kHz, includes calibration certificate and acoustic calibrator
CEL-620A/2/K1 is a portable handheld sound level meter, decibel meter, sound pressure level (SPL) meter or sound level indicator that uses advanced digital technology to deliver high performance noise exposure evaluation capabilities in a compact yet robust design. The meter features a high-resolution color TFT display and allows for the analysis of octave bands in real time.

This CEL-620 series sound level meter measures average noise levels as well as peak levels, making the device the ideal solution for monitoring noise exposure in the workplace. The sound level meter also measures LC and LA simultaneously using the HML method for the selection of auditory protection.
