The CEL-240 will be an ideal instrument for industrial hygiene measurements of noise in the workplace. The meter has a low and high measurement range that covers a full 70dB on each range. It can be used for machinery noise surveys as well as all general purpose workplace noise level measurements. With the A and C frequency scales and the S, F and I time response the meter can be used to assess the right hearing protectors using the NRR method. A non-decaying maximum hold feature on every display captures and displays the highest sound pressure level of any noise until reset by the user.
