The Pulsar Instrument – Ultra Simple Sound Level Meter

Combining computer technology with ultra simple operation, the Pulsar Instruments (UK) sound level meter model 14 is an entry level instrument intended to be used primarily for factory surveys to enable employers to meet the “Noise at Work” regulations at the lowest possible cost.
As well as simplicity in operation, particular attention has been paid to the display and a new design of LCD has been used with very high legibility in all light conditions. The unit has not only the A-frequency-weighting required by the EU directive, but as well, C- Frequency-weighting, both with F-time-weighting or what was traditionally called ‘Fast response’.

The intent of the model 14 is to carry out an initial survey of factories and other workplace where the noise levels are not expected to be very high. If during and initial survey, no noise level is found that is over say 75dBA, no worker can be exposed to dangerous noise levels and the employer can be confident that he is fully compliant with the current regulations. Even if one or more slightly higher levels are found, these can be avoided or a more complex Leq meter can be used to quantify the average level, or a Personal Sound Exposure meter such as the Pulsar Model 22 ‘doseBadge’ used to measure the noise exposure of individual workers. A high sensitivity range is also fitted, going down to 35 decibels to allow noise to be checked at the boundary of any premises to ensure that noise is not escaping from a workplace.

A major problem with measuring noise accurately for the purposes of the EU directive is the presence of many ultra low cost units, intended for hi-fi. That can be bought from many non-professional retail outlets, but these are simply not suitable for measuring industrial noise as they have not been checked for accuracy and in general cannot be officially approved. Model 14 is normally supplied as a kit including a calibrator – mandated by the Directive as well as the operating manual etc, housed in a carrying pouch and fully complies with the latest International standards IEC 61672 at Class 2 level as well as the older IEC 60651 Type 2.lt therefore offers the lowest cost fully compliant meter available on the European market.
Pulsar Instruments plc have been manufacturing high quality sound measuring equipment since 1969, in the USA and Uk and offer their standard 2 – year warranty with model 14 that can be extended at no cost, when the instrument is regularly calibrated.
