The CEL-240 series includes two primarily instrument types, the CEL-240 and CEL-242 basic sound meters, and the CEL-244 and CEL-246 integrating meters. The CEL-242/ 246 feature basic datalogging capabilities. CEL-240 sound level meters are suitable for a range of simple noise measurement applications, are ideal for industrial hygiene measurement of workplace noise, and comply with ANSI and IEC Type 2 accuracy specifications. All CEL-240 series sound level meters support two measurement ranges and can display maximum and instantaneous values. In addition, the CEL-244/ 246 support the time average values Leq or Lavg. The CEL-240 supports impulse, fast, and slow time weightings on A or C scale. Other CEL-240 features include a wide sound monitoring range from 30– 130 dB, a monochrome LCD screen, scrolling sound level display, and auto-calibration at either 114 or 94 1 kHz decibel levels. Digital output of audio is possible through USB and the CEL-240 can also provide an audio feed to a computer or external recorder through a 2.5 mm audio jack. Standard measurement and optional computer output kits are available. CEL-240 series instruments are powered by three AA alkaline batteries for up to 35 hours of use and can also be powered continuously through a computer or a mains-to-USB adapter. CEL-240 Series Features 4 models; 2 basic sound meters, 2 integrating meters Output to PC for simple data logging capabilities ( select models) Wide sound monitoring range from 30– 130 dB Impulse, Fast, Slow time weightings on A or C scale Auto calibration at either 114 or 94 1 kHz decibel level Large monochrome graphic LCD with numeric and bar graph output Screen displays current, highest, time average noise levels Scrolling display of sound level 3 AA alkaline batteries for up to 35 hours of use
