Pulsar “Noise Assessor”: hard to beat for simplicity

Find out why the Assessor is renowned as the simplest approved noise meter available for Industrial Health & Safety

Nov 21, 2011

The Pulsar Instruments plc "Assessor" is renowned as the simplest approved noise meter available for industrial Health and Safety. With only four buttons and a display that gives its user full data on all the parameters the European Directive and Health & Safety Executive (HSE) require, it is hard to beat for simplicity. It is truly a "point and shoot" meter where, in a single measurement, all the data is gathered to demonstrate compliance with the Noise at Work regulations.

However, the original Pulsar "Noise Assessor" was never intended to be used as a diagnostic tool to determine the choice of personal hearing protection. Indeed, conventional wisdom has always been that "simple to use" and "diagnostic" were mutually incompatible.  This version of the Assessor changes this and allows even the biggest technophobe to make quick and accurate measurements to select the appropriate hearing protection for a wide range of noises and in many different areas.

 Introducing Pulsar Models 81CA & 82CA

The two models in question here have only one extra button, making a total of five.  As such, compared with competing instruments that are complex to operate, the Assessor is truly a revolution in measurement simplicity. The Pulsar Assessor uses the HML or High-Medium-Low selection method. Visit the Health & Safety Executive website where you will find a simple spreadsheet to input the data given by the Assessor for a comprehensive selection of hearing protection or PPE.

In use, the sound level meter is simply turned ON and the reading taken allowed to settle.  The instrument then automatically measures all the legally required parameters AND also gives the "C minus A" metric - also known as [LCeq - LAeq]. 

This addition to the existing popular Noise Assessor range is available in two variants, both completely complying with the current international standard IEC 61672:  The Model 81CA at Laboratory Precision Class 1 level, while the lower cost Pulsar Model 82CA complies with Class 2 industrial accuracy.  As with all Pulsar Instruments, the noise meters are normally supplied as a full noise measuring kit with everything needed to make the measurements.
