Applications

105&106Application Most noise related regulations stipulate that the sound level meter or dosemeter is calibrated before each measurement session and checked again before turning the instrument off. Noise measurements made for ‘official’ use, such as industrial health & safety or environmental monitoring, are not valid unless correct calibration procedures have been followed.
