Cirrus doseBadge

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 doseBadge contains the microphone, a rechargeable battery and the electronics to acquire and analyze the levels continuously.

  • IEC 61252 and ANSI S1.25 to Type 2
  • Suitable for ISO, OSHA, MSHA, AICHE and ACGIH noise applications
  • Intrinsically Safe version available
  • No wires or controls on the badge to catch or knock
  • Very rugged cast aluminum case
  • Powered by a rechargeable battery
  • Time History gives a graph of noise levels
  • Noise measurement span from 70 to 130 dB(A)
  • True Peak reading from 120 to 140 dB(C)

The Reader

The Reader has a built in doseBadge calibrator and can show the results of measurements on its display or transfer them to a computer using the software supplied.

Complete Noise Dosimeter Kits

Complete measurement kits are supplied, including doseBadge noise dosimeter, Reader, charging unit, software and doseBadge mounts. Everything needed to make the noise dose measurements with no hidden costs.
