The CEL 110 is designed and manufactured to comply with requirements of the new IEC 60942 (3rd edition 2003) Acoustic Calibrator standard.This latest standard ensures accurate calibration over a wide range of temperature, humidity and pressure conditions, typical of field work, making this calibrator an integral part of your measurement kit.
It features dual calibration levels at 94 & 114dB on Class 1 and 114 dB only on Class 2. A clear lcd display indicates a digital readout of the actual dB level and indication of correct microphone insertion.
