The CEL-633 Type 2 sound level meter is an easy to use instrument designed to undertake the measurement requirements of workplace and environmental noise. It also complies with the latest IEC and ANSI international standards for sound level meters. Just switch on the instrument, auto-calibrate and start measuring with one of the predefined views. Regardless of the view selected, all data is measured and stored simultaneously so no mistakes can be made. By implementing the latest digital technology, the meter has a single measurement range so no adjustment is required, ensuring the highest levels of performance with all noise sources. Models are available for both environmental and/or occupational noise with the availability of frequency analysis and advance functions such as data markers,timers and logging of time history data. Even with such advanced functionality, the CEL-630 Series remains very simple to use.
The CEL-633C1/K1 kit includes: meter, calibrator, wrist strap, foam windscreen, USB cable, Insight Plugin and small kit case.
