MSHA Approved Noise Dosimeter Kit with 5 x I.S.doseBadges (OSHA)
1 week

FM Approved Noise Dosimeter Kit with 5 x doseBadges (NIOSH)
2 weeks


  • Intrinsically safe noise dosimeter
  • MSHA or FM approvals
  • Strong metal case
  • Shoulder mounted
  • Measures noise exposure
  • 15 Year Warranty


  • Petrochemical and mining industries
  • Hazardous and potentially explosive atmospheres
  • Occupational noise surveys
  • Noise dosimetry
  • Hearing protection


This is the intrinsically safe version of the doseBadge Noise Dosimeter. With approvals for use in potentially explosive environments, as found in the mining and petrochemical industries, the doseBadge mounts on a worker's shoulder and continuously measures the noise dose.

At the end of the work shift the doseBadge noise dosimeter calculates the noise exposure (dose %). Using the software, which is included, you can produce useful occupational noise reports, including a graph of the sound level over time so you can see when any high sound levels occur.

The noise measurements kit (order codes start CK) include doseBadges, a Calibrator, software, everything that you need to make noise assessments.

Intrinsically Safe

Shoulder Mounted Noise Dosimeter

The CR110AIS and CR112AIS versions of the doseBadge are approved for use in hazardous and potentially explosive atmospheres, making them ideal for the petrochemical industry and underground mining.

The CK112AIS/x kits have MSHA approval, for use in the mining industry, following the OSHA noise measurement regulations. The CR110AIS/x kits have FM approval for other applications. See the IS Approvals tab for more information on intrinsic safety approvals.

doseBadge Noise Dosimeter

The doseBadge intrinsically safe noise dosimeter is the part that mounts on the worker's shoulder. It is a small, lightweight device that should not interfere with the worker's duties.

The doseBadge is the only part of the system that is I.S. approved as this is the only part that needs to be present in the hazardous environment.

Weighing just 51g (1.8oz), the doseBadge has no cables or controls, making it safer around machinery and limiting the effects of tampering.

The dosimeter should be fitted to the worker at the start of the day or working shift and left to measure the total noise exposure.

Noise Measurements Made

The main measurements made by the I.S. doseBadge are:

  • TWA - time weighted average
  • Dose % - exposure as a percentage
  • Lavg or LAeq - the A weighted average sound level
  • Peak - the maximum peak pressure
  • Time History - average every minute

The MSHA / OSHA version of the doseBadge has two channels, one measuring with a threshold of 80 dB and the other with a threshold of 90 dB. This is needed for the two types of measurements needed for this particular set of regulations. The FM / NIOSH version of the doseBadge has one channel set to meet the requirements of NIOSH and the other channel can be configured as required, in case you have other regulations to meet.

Noise Dose Exceeded

noise dose level exceeded

The doseBadge can be set to indicate when the noise dose has exceeded 100% (e.g. 85 dBA for 8 hours). Under normal conditions, the blue LED flashes once every second. When the noise exposure limit is exceeded, it flashes twice every second.

Intrinsic Safety Approvals

These approvals apply to the CR112AIS and CR110AIS versions of the doseBadge noise dosimeter, which are included in the CK112AIS/x and CK110AIS/x noise dose kits.

Intrinsic Safety Certification

The Intrinsically Safe versions of the doseBadge have been independently tested and verified by a number of different test laboratories to ensure that it meets the requirements of the different Intrinsic Safety standards.

These tests ensure that under defined test conditions the doseBadge will not cause a spark or will not heat up and cause a flammable atmosphere to ignite. Within these standards there are many different levels of performance and it is essential that you have the correct level of performance for the environment in which your equipment will be used.

Limitations of the Intrinsic Safety Approval

Only the doseBadge itself (the shoulder mounted part) and its mounting are approved for use in potentially explosive atmospheres. None of the additional items, such as the Reader and Charger are approved. All tasks such as charging, calibrating and initializing the doseBadge should be done outside the hazardous area.

CR112AIS MSHA I.S. doseBadge

The CR112AIS version of the Intrinsically Safe doseBadge has MSHA approval for use in mining applications.

  • MSHA: Intrinsic Safety Approval (No. 18-A060027-0)

CR110AIS Intrinsically Safe doseBadge

The CR110AIS has ATEX, EEx, IECEx and FM approval for use in Group I non-mining and Group II mining applications.

Group I Non-Mining Applications:

  • FM: IS / I / 1 / ABCD / T4 Ta <= 60°C; Type IP54, I / 0 / AEx ia / IIC / T4 Ta <= 60°C; Type IP54
  • ATEX: CE Ex II 1 G
  • IECEx: IECEx BAS 06.0084, Ex ia IIC T4 (-20°C <= Ta <= +60°C)
  • EEx: EEx ia IIC T4 (-20°C <= Ta <= +60°C)

Group II Mining Applications

  • ATEX: CE Ex I M1
  • IECEx: IECEx BAS 06.0083X, Ex ia I (-20°C <= Ta <= +60°C)
  • EEx: EEx ia I (-20°C <= Ta <= +60°C)

Start of the Working Day

  • Fit the doseBadge onto the Reader and press the Reset key to clear its memory
  • Calibrate the doseBadge by pressing the Cal key
  • Attach the doseBadge to the worker using the supplied fixing
  • Point the Reader at the doseBadge and press the Run key

Leave the doseBadge measuring for the full working shift...

End of the Working Day

  • Point the Reader at the doseBadge and press the Stop key
  • Remove the doseBadge from the worker and fit it onto the Reader
  • Press the Cal key if you want a second calibration
  • Press Read to transfer the results to the Reader
  • Put the doseBadge on to charge to be ready for another day's monitoring

The measurements can be viewed on the Reader's built in graphic screen or they can be transferred to a computer for storage, analysis and reporting. The Reader can download a number of doseBadges before the measurements are transferred to a computer, so it is only necessary to carry the Reader on site.

doseBadge Software

The doseBadge kits include the NoiseTools software, which is used to download the measurements from the Reader and produce noise reports.

  • Download, store and organise noise measurements
  • View measurements on screen
  • Produce reports then print or export them for sharing
  • Link measurements to people, places or projects
  • Backup and archive noise measurement data

The NoiseTools software runs on a Windows PC, supporting versions 7, 8 and 10. There are no license restrictions so it can be installed on as many computers as needed.

doseBadge Dosimeter Kits

Although doseBadges and Readers can be bought individually, they are usually included in a complete noise measurement kit that includes everything you need to make occupational noise measurements.

The CK112AIS/x and CK110AIS/x kits include:

doseBadgesStandard kits include 1, 2, 3, 5 or 10 doseBadge dosimeters, but other quantities can be supplied
ReaderOne Reader unit is used with multiple doseBadges
CalibratorBuilt in to the Reader unit
doseBadge MountsOne mount for each doseBadge
ChargerFor charging the doseBadge batteries
SoftwareThe NoiseTools software
CertificatesCalibration certificates for each doseBadge and Reader (calibrator)
Carrying CaseHolds all doseBadges, Reader, charger and manuals

Optional Items

dosebadge windshield

Windshield The doseBadge windshield not only reduces the noise from strong wind but also provides additional protection against light rainfall, dust and the noise generated by knocks against the microphone.

Helmet Mount These allow the doseBadge to be fitted on the side of a helmet that is fitted with earmuff mounts. Note that the helmet mount is not approved for use in hazardous environments.

remote control keyfob

Keyfob Remote Control The Keyfob can be used instead of the Reader to Start and Stop the doseBadge. You still need a Reader to calibrate and reset the doseBadge but the Keyfob is much more handy for use in the field.
