Features of the doseBadge Noise Dosemeter

  • No wires or controls on the badge to catch or knock
  • Simultaneous, dual channel measurements:
    • Channel 1, programmable exchange rate, time weighting, criterion time and level
      • Example: OSHA Q=5dB: Lavg, Dose %, TWA and Peak
    • Channel 2
      • Q=3dB (ISO): Leq, Dose %, Lep,d and Peak
  • "A" frequency weighting with "C" weighting for Peak
  • Very rugged cast alloy case
  • Powered by an internal rechargeable battery
  • doseBadge and Reader communicate using an infra-red link
  • Supplied with software to download measurements to a Windows PC
  • User programmable to either Q=3 (ISO) or Q=5 (OSHA)
  • Time history gives graph of noise levels
  • Measures down to 70 dB(A)
  • True Peak reading with Peak Time history
  • 115 dB(A) sound level exceeded flag
  • Extra user-programmable settings for MSHA, AICHE and ACGIH noise regulations
