CEL620A Sound Level Meter


The CEL620A is an Integrating Sound Level Meter that provides you with all the measurements needed for a detailed occupational noise survey and subsequent hearing protection assessment.

  • Occupational Noise Measurement
  • Hearing Protection Assessment
  • Data logging with download to computer
  • Quick and easy to use
  • Simultaneous measurement of parameters (Lavg, Leq, TWA, Max, Min)
  • Single range 20 to 140 dB


  • ANSI S1.4 and ANSI S1.43 - Type 1 or Type 2
  • IEC 61672 - Class 1 or Class 2
  • IEC 60651 and IEC 60804 - Type 1 or Type 2
  • OSHA, MSHA, ACGIH, European and other regulations

Integrating Sound Level Meter

The CEL620A provides a large set of parameters, such as "A" and "C" weighted Max, Min and Peak. As an Integrating sound level meter, the CEL620 also provides the average sound level Lavg and Leq. All measurements are made in parallel, which means you do not need to decide beforehand which ones you need - they are all stored.

Occupational Noise Regulations - OSHA and Others

All the CEL620 series meters are suitable for measurement to the USA standards OSHA, ACGIH, MSHA as well as regulations from all other parts of the world. Most regulations (including OSHA) require the use of a Type 2 calibrated meter that can measure the Lavg to enable accurate TWA noise exposure calculations. The CEL620A also measures the Peak for loud banging noise along with "A" and "C" weighting for hearing protector checks.

Data Logging and Software

The CEL620A comes complete with data logging capability. Measurements are stored in the meter's internal memory. When connected to a Windows computer, the meter acts like a memory card (shows as a removable drive) so the measurements can be loaded into a spreadsheet or moved to your hard drive for long term storage. There is no need to buy and install special software, which can be a real benefit on a company network where the installation of software is not encouraged.

For occupational noise assessments you can also use our NoiseMeters Applications web based system. Measurements can be transfered to our server without the need to install software, and reports generated from within your web browser. For NoiseMeters Applications please include item NMAPPS with your order.

sound meter softwareIf you want a little more than just loading the measurements into a spreadsheet then the Insight software simplifies the process of downloading the measurements, storing them in a database, managed by person, place or process criteria. To get the Insight software for the CEL620A include item ISC020 with your order.


Our Recommendation

For occupational noise measurements, we recommend order code CEL620A2-K, which includes the Type 2 CEL620A2 and Calibrator. The standard meter is data logging and measurements can be transferred to a spreadsheet or to our web based NoiseMeters Applications.

For advanced users the Insight software can make the download and analysis process easier and more powerful. If you are unsure, Insight can be ordered at a later date.
