Pulsar Model 82CA/81CA Integrating Sound Level Meters

With dB(C)-dB(A) Function

Back to 80 Series Overview

  Automatic C-A measurement mode
  Ideal for HML method of hearing protection calculation
  Hearing protection measurements have never been easier; The C-A mode ensures automatic measurement calculation
  Expands the original concept of the basic Assessor for those with noisy work places that prefer an affordable but legal method of specifying suitable hearing protection measurements

The Models 82CA & 81CA are the ideal instruments for those who do not want to pay extra for an instrument with 1:1 Octave Band Filters because the HML method (High, Medium and Low), is an established and accepted method of calculating hearing protection.

All hearing protection (PPE) should be supplied by the manufacturer with attenuation (reduction) values for each of the H, M and L values.

By knowing the 'C' and 'A'weighted Leq values and the difference between them you can use either a spreadsheet or simple formula to prescribe suitable hearing protection for your workforce.

C-A measurement mode

By just pressing the C-A button, the instrument will automatically switch to 'C-A' Measurement Mode. A blue LED indicator shows that you are now measuring in 'C-A' mode rather than the normal 'Broadband' mode.

The instrument will make an Leq measurement with dB(C) Weighting (LCeq) and will continue until the average level has settled. When the level has settled, the instrument will switch to dB(A) and repeat the process with 'A' weighting. When this level has also settled, the instrument will display the LCeq, LAeq and in large digits, the resultant LCeq-LAeq value on the screen.

Making this type of measurement has never been easier as everything is done in an automatic cycle for you.
