Description

ThisCEL-620B1-K1complete kits comes with acoustic calibrator (CEL-120), kit case,windshield, instruction manuals and USB cable.Kits come complete with Casella Insight Data Management Software,see Insight data sheet for more details. Using a high resolution colour TFT display, the 62Xseries is specifically designed toensure takingnoise measurements is quick and easy.This model is suitable forindustrial hygiene requirements where octave band analysis isrequired for the effective selection of hearing protection.TheCEL-620B1 is a Type I Meter. All 62X models are integrating so measure average noise levels as well as peak levels for workplace noise legislation. CEL-620A model also simultaneously measures the LC and LA used within the HML method for the selection of hearing protection. In addition, the CEL- 620B model performs real-time octave band analysis from 16Hz to 16kHz, values which are used in the octave band method for selection of hearing protection. If future requirements change, any instrument can be upgraded to a higher model without returning to Casella. Complete measurement kits are provided with an acoustic calibrator in a robust kit case complete with instruction manuals and calibration certificates.

Key Features

- Compact, rugged design - Simple operation - Single large measurement range - Large memory - High resolution colour display - Real-time octave band analysis (B models) - Simultaneous measurement of all workplace noiseparameters - Instrument menu in 9 languages - Pre-defined and user configurations available - Automatic calibration function - Long battery life

Simple Operation

The 62x series was designed with ease of use in mind. The menu structure is designed to pick up and use without the use of a manual. A simple icon structure is used with word prompts for each selection, available in seven languages. The instrument has six selectable set-ups. Four pre-defined setups can be used to satisfy local workplace noise legislation. Two user set-ups can be defined to display parameters and weightings as required. Regardless of the setup used, the 62x series measures and stores all parameters and weightings even if not selected. These can be viewed if necessary on the software. Up to 100 measurements can be stored without the need to download. All runs are date and time stamped. When connected to a PC via the USB connection, the 62x series acts like a memory card, so data files can be moved to a PC and easily reviewed without the need for proprietary software.

Digital Technology

By using Digital Signal Processing (DSP) technology, the 62x series measures all the workplace noise parameters simultaneously with necessary time and frequency weightings, preventing incorrect setup of the instrument. The instrument has a single large measurement range of 20-140dB, eliminating the need to change measurement range and preventing errors. On the CEL-620B model, octave analysis is performed in realtime, saving time compared to performing measurements sequentially. Octave band results are shown in both bar-graph and tabular form with the dominant frequency highlighted. Time history of the broadband noise level is displayed in real-time, so a user can see how the noise level varies with time.
