CEL-630 octave band sound level meter, noise spectrum analyzer

CEL-630 octave band sound level meter, noise spectrum analyzerThe instrument is a professional sound level meter suitable for precise measurement in the field of workplace and environmental noise. The product has powerful and comprehensive functions, adopts the latest digital technology, and fully complies withIECStandards andANSIThe international standards for sound level meters are fast to operate and easy to use. Users only need to turn on the machine power to automatically calibrate and measure according to the preset parameters, regardless of what parameters are measured,CEL-630All data will be automatically recorded and saved in the machine memory, so that users will not miss any measurement parameters that may be needed and there will be no errors.

CEL-630The series of digital sound level meters and noise spectrum analyzers have advanced functions and are easy to use. The recording isCEL-630The basic function of all products in the series is that all models can perform voice recording. Users can annotate the results by speaking into the microphone before and after the measurement, eliminating the need for manual recording. The ability to 'mark' data during the measurement process means that abnormal or important events and audio can also be recorded for subsequent noise source identification. If the instrument is used for unmanned measurement, recording can be triggered by a condition (such as exceeding a certain level for a period of time). In this case, additional data will also be collected along with the audio. This is particularly important when the noise source is fleeting.

CEL-630Adopting multiple latest digital technologies and using a single range measurement mode, users do not need to manually adjust the measurement range, ensuring high-level performance under all noise sources. Additionally,CEL-630Environmental noise and occupational health modes can be selected for measurement, both of which can use spectrum analysis and time weighting functions, and can record historical data over time (sound pressure level changes over time). The powerful, comprehensive features and fast and easy-to-use characteristics makeCEL-360Becoming one of the best professional noise measurement tools in the industry, it is a trustworthy environmental noise and occupational health measurement equipment.
