Assessor 81CA & 82CA Industrial Noise Level Meter

The Assessor 81CA (Class 1) and 82CA (Class 2) are industrial noise level meters ideal for affordable hearing protection prescription. This meter uses ‘C’ and ‘A’ weighted Leq values and the HML method of calculating required hearing PPE.

Description

Industrial noise level meter

Expanding on the basic models in the Assessor range, the Assessor 81CA and 82CA effectively combine affordable noise measurement and compliance with International Industrial Noise Directives.

This integrating sound level meter is the ideal instrument for those people who are happy to use the established HML method (High, Medium, Low) of Hearing Protection Prescription and do not want an instrument with 1:1 Octave Band Filters.

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 instrument 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 integrating sound 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 the screen. Making taking this HML method of measurement has never been easier, as everything is done in an automatic cycle for you.

Data logging

There is also an option to upgrade the meter to include data logging so that you can store your measurements to the internal memory and then download to create reports using the Pulsar Analyser software.
