The Original doseBadge

Everything you need for occupational noise and industrial hygiene measurements

The doseBadge noise dosimeter system is the perfect solution for measuring a worker’s noise dose exposure. The badge is small and light, with no cable or controls and mounts comfortably on the worker’s shoulder. The dosimeter is then left on the worker, storing details about the noise levels throughout the day.

The doseBadge has no controls or display and all control is over the infra-red link to the Reader.  The doseBadge case is a lightweight alloy, giving added strength to the already strong cone shape.

The Original doseBadge noise dosimeter is a dual-channel instrument that will measure, store, and calculate the parameters essential for compliance with occupational noise regulations.

These include LAeq, LCPeak & LEP,d and % Dose, LAVG & TWA. Along with these overall values, the Original doseBadge will store a Time History, or Noise Profile, throughout the measurement, for both channels.

The Original doseBadge survives in the harshest environments

The Original doseBadge has been designed to survive in the toughest and harshest environments. There are no cables, controls or displays to damage, and the microphone, battery and electronics are all housed in a robust and lightweight metal case which is strong enough to withstand being dropped, knocked or even stood on.

Applications for the Original doseBadge Noise Dosimeter

Due to its unique and robust design, the doseBadge is used across a wide range of applications where there is a need to assess workers’ noise exposure, such as:

The measurement and control of occupational noise exposure
Compliance with Noise at Work Regulations, Industrial Hygiene Standards and Occupational Noise Exposure Guidelines.
Monitoring and recording term noise exposure

Simple to use

Using the Original doseBadge Noise Dosimeter

Each Complete Kit is supplied with a Reader unit. One Reader can be used to control as many doseBadges as you need.

The Reader is used to carry out the following functions:

Reset and Calibrate the doseBadge
Start the doseBadge running (after fitting it to the worker's shoulder)
Stop the doseBadge at the end of the day
Read and Display the noise measurement results
Download to computer

The Reader has a built in Calibrator, operating at 1 kHz, 114 dB.

To calibrate the dosimeter, simply push it into the calibration cavity and press the Cal button on the Reader. The calibration process is automatic and the results are recorded, along with any automatic adjustments that are made.

The Reader unit can also be used to configure the doseBadge settings. The doseBadge can be configured to meet the ISO Q=3 (for European regulations) and OSHA Q=5 (for the American standards).

The Exchange Rate, Criterion Level, Criterion Time, Threshold and Slow Time Weighting can be set individually in order to meet other standards such as those published by MSHA, AICHE and ACGIH. See the Noise Regulations page for more information.

As the doseBadge has Dual Channels, it can have Channel 1 set to OSHA, MSHA, AICHE, ACGIH or similar, with Channel 2 fixed to measure with the common ISO 3dB settings.
