Brief introduction: The CASELLA CEL-63X series is designed to make noise monitoring in the workplace quick and easy. Different data can be displayed as required, and all monitoring data can be saved at the same time without any monitoring errors caused by improper Settings. When cooperating with CEL-120 series sound level calibrator for calibration, calibration time and date will be stored and imported into PC software to verify the accuracy of monitoring. Average, peak, and octave monitoring are performed simultaneously, so all workplace noise monitoring data can be measured in one run. Main features: • ideal environment and workplace noise monitoring instrument • simple operation and easy to use • circuit design using digital technology • high resolution color TFT display • preset occupational and environmental monitoring configurations • voice tags can be added • recordable noise audio (wav) • single range up to 140dB, no manual adjustment of the range • data marking, erasing function • support event triggering • real-time octave and 1/3 octave noise monitoring • all parameters monitored at the same time as well as the calculated weights of frequency and time • level 1 and level 2 accuracy are supported •2GB of memory can store more than one year's data • removable preamplifier adapter • optional outdoor environmental monitoring suite Technical parameters: General performance: Range: 20-140db RMS (peak 143.3db) Background noise: 19dB(A) level 1, 25db (A) level 2 Time weighting: fast, slow and pulse (simultaneous) Frequency weighting: A, C and Z (no weighting) (simultaneous) Frequency band: 11 octave range 16hz-16khz (B&C model); 33 octave band 12.5 hz-20khz (type C) Amplitude weighting (Q) : 3, 4 and 5 (simultaneously) Back erase: last 10 seconds in cumulative mode (all models) Timer: lasts 1 second to 24 hours Turn timer on/off: 6 Settings with optional time and repetition Measurement parameters: Full frequency band: Lxy Lxymax Lxymin Lxeq Lxpeak Lavg lc-la Lxleq Ltm3 Ltm5 Lae Physical properties: Tripod: 1/4 "wyeth threaded socket Power pool: 3 AA alkaline batteries, 10 to 15 hours (depending on background brightness) External power supply: 9-14v DC, 150mA 230*72*31mm includes a preamplifier and microphone Storage: Memory: 2GB (records over 1 year and 999 runs when 1-second intervals are set). All parameters are stored and read by Casella Insight software. Total measurement run 999 times. Events: 999 events can be logged per run. High quality mode can record 10 hours, low quality mode 60 hours. For long periods of unmonitored use, CEL 630 runs once a day for a total of 400 days. The recording Low quality: 8 bits (64kb/ SEC) for 8000 data/SEC up to 4kHz High quality: 24000 data/SEC at 8 bits (192kb/ SEC), up to a maximum of 12kHz Working environment: Relative humidity 5-90%(no condensation) Temperature - 10 - to + 50 ℃ (rank 1), 0 to + 40 ℃ (level 2) The atmosphere is 65 to 108 kilopascals Language: User interface languages can be changed through menus: English, French, German, Spanish, Italian, Portuguese, and Chinese Workplace noise monitoring • monitor all noise parameters in the workplace at the same time • comply with monitoring standards of workplace noise regulations • help select hearing protection measures (SNR,HML and octave) • analyze the time history data of noise level • optional high range microphone, up to 165dB
