Assessor Integrating Sound Level Meter Models 81CA & 82CA

(1)

Models 81CA & 82CA for Affordable Hearing Protection Prescription:

Expanding on the basic models in the Assessor range, the Models 81CA and 82CA effectively combine affordable noise measurement and compliances with International Industrial Noise Directives; these models use the established HML method of calculating required hearing PPE and are the ideal noise measurement instruments for people who do not want to pay extra for an instrument with 1:1 Octave band filters

Noise Level Meter

Both the Model 81CA (Class 1) & 82CA (Class 2) Noise Level Meter is the ideal instruments for those who do not want an instrument with 1:1 Octave Band Filters when the HML method (High, Medium and Low), is an established and accepted method of calculating hearing protection requirements.

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 select suitable hearing protection for your workforce.

C-A Measurement Mode

By just pressing the C-A button, the instruments will automatically switch to ‘C-A’ Measurement Mode. A Blue indicator shows that you are now measuring in C-A mode rather than the normal Broadband mode.

The noise level meter 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 screen. Making this type of measurement has never been easier, as everything is done in an automatic cycle for you.

Features

  • The Model 82CA (Class 2) and 81CA (Class 1) have all the features of the Assessor 81A and 82A but with the addition of an affordable and legally compliant way of specifying hearing protection.

DHL Supply Chain
Following a claim we were defending, we were asked by our lawyers to supply noise measurement samples for a particular area in our factory. At this point, none of our managers were trained in noise assessment and it looked like we would have to pay out thousands of pounds to hire a consultant to give us all of the required information. After attending the Safety & Health Expo in Birmingham, we decided to purchase the Pulsar Assessor kit at just over one thousand pounds and arranged for Pulsar to present a Noise Awareness training day at our site in Warrington. We carried out our own assessment the next day after the training, downloaded all of the details onto the database supplied with the equipment, which gave us the measurements over an 8 hour period in minutes, graphs explaining the different levels at given times and this helped us identify if there were any issues in the problem area and even the type of PPE we would have to issue. The site then sent off all of this information to our lawyers who successfully defended the case saving the business in excess of seven thousand pounds.
