Using a high resolution colour TFT display, the Casella 62x series is specifically designed to ensure taking noise measurements is quick and easy. Different models are available depending on your requirements for use in general workplace noise measurements, up to full industrial hygiene requirements where octave band analysis is required for the effective selection of hearing protection.
Key Features
- Real-time measurement of octave bands
- Used for the selection of hearing protection (Octave or HML Methods)
- Full colour display, simple to operate
- Single measurement range even in octave modes
- IEC 61762 Class 1 or Class 2 models available
- Measures all workplace noise parameters simultaneously
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.
Applications
- Occupational Noise Measurement
- Workplace noise according to ISO9612 and OSHA 29CFR 1910.95
- Selection of hearing protection
- Calculation of noise exposure
- Ensuring compliance with workplace noise legislation
- Machinery noise tests
