Overview:
The CEL-620 Series Enhanced has new features including:
- Time history storage (Selectable from 1s to 30min)
- Larger memory (999 runs)
- Voice notes (Up to 33 hours of audio storage)
- GPS
The CEL-620 Enhanced digital Sound Level meters can be used for the measurement of all workplace noise parameters to comply with workplace noise legislation, e.g. EU, OSHA and ACGIH. Use the CEL-620 Series to carry out occupational noise assessments or machinery noise tests as well as to assist with the selection of hearing protection.
Choose a CEL-620 Series model to suit your requirements, either with a Class 1 or Class 2 Microphone for precision, and with or without Octave Band analysis, to aid you in the choice of hearing protection. The CEL-620 is a simple to use meter and data is displayed on the high resolution colour display. Measurement screens are intuitively colour coded according to the mode of operation, i.e. green if a measurement is being taken and red when a run has ended.
Data is graphically displayed to give a clearer picture of the noise environment. Calibrate easily on-site with the 120 Series Calibrator to comply with best practice. The instrument also has six selectable setups – four that are pre-defined to legislative standards and two that can be customised so that you get the data you need.
Regardless of the setup, the CEL-620 measures and stores ALL parameters, even if not selected and these can be viewed in the software. All runs are date and time stamped and the CEL-620 stores up to 999 runs. The 999 runs can be up to 24 hours each, even with the 1s time history stored. Simply connect your CEL-620 to a PC via the USB connection and the data can be easily reviewed without the need for proprietary software.
The instrument has a single large measurement range of 20-140dB meaning that you don’t need to change range. On the CEL-620B, Octave band analysis is shown in real-time in both graphical and tabular format with the dominant frequency highlighted.

Digital Technology:
The 620 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
real-time, 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 and stored in selectable 1s to 30min intervals, so a user can see how the noise level varies with time.

Tabular octave results
Simple Operation:
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.
The instrument has six selectable set-ups. Four pre-defined set-ups can be used to satisfy local workplace noise legislation. Two user set-ups can be defined to display parameters and weightings as required.
Up to 999 measurements can be stored without the need to download. All runs are date and time stamped.
• Intuitive menu structure
• Multilingual user interface
• Predefined and user selectable set-ups
Set-up selection
The 620 series uses colours on the high-resolution display to aid the user in making measurements. Measurement screens are colour coded depending on the mode of operation.
