Casella CEL 240 Type 2 Sound Level Meter Rental

The CEL-240 is a simple general purpose sound level meter that is ideal for use in many situations where a quick idea of the current noise level is needed. It features 2 ranges from 30 to 100 db and 60 to 130 db and provides the standardized A and C broadband frequency weightings required by many protocols. The CEL-240 also has the Slow, Fast and Impulse time responses. A maximum hold function with a user reset is available to capture the highest level of noise to give a "worst case" measurement if needed. Results are displayed on a graphic LCD in either alpha numeric format or as a scrolling time history graph with either 1 or 5 minutes time history so that recent peaks and troughs may be viewed.

Calibration is as simple as placing the calibrator over the microphone and switching it on. As soon as the calibration tone is steady it is automatically detected by the CEL-240 and the user is offered the choice of performing the calibration with a single button press. There is no need to use old fashioned screwdrivers that may get lost as the calibration takes just 5 seconds and is very easy to perform.

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 nondecaying maximum hold feature on every display captures and displays the highest sound pressure level of any noise until reset by the user.
