Analyser Software

Another key benefit of the Model 84 & 83 instruments is that they do not need to be upgraded. They are supplied as data logging instruments with the Pulsar Analyser software and download cable supplied as standard.

In other words they can store data in the internal memory and allow this information to be downloaded and reports created using the excellent Pulsar Analyser download /analysis reporting software suite.

The software also has a special database of hearing protection that allows you, at the click of an icon, to have all calculations done for you automatically. You then select the hearing protectors of your choice and print out a full report justifying your selection.
