The Safety Officer's Noise Measurement Kit is a complete set of noise measurement tools that can be configured to meet your needs.

The kits contains a combination of an Optimus Sound Level Meter along with the doseBadge noise dosimeters and accessories for each instrument. All of these components are supplied in a single robust carry case.

Choose your ideal combination of instruments.

Simply select the Optimus SLM and the number of doseBadges that meets your needs. The doseBadges can be either the standard CR:110A version or the Intrinsically Safe CR:110AIS version which carry TEX, EEx, IECEx and FM certifications.

If you are measuring occupational noise, such as the Noise at Work Regulations or OSHA, choose from the Optimus Red (CR:160 Series). If you need to make environmental noise measurements or if you need to cover both environmental and occupational noise, choose one of the Optimus Green (CR:170 series)
