带记录数字噪声计Models93&94

The Model 93 (Class 1) and Model 94 (Class 2) offer all the measurement functions of the Models 91 and 92 with the addition of 1:1 Octave Band Filters.

For Industrial Noise measurements these models offer 1:1 Octave Band Filters for the selection of accurate hearing protection. You can then choose your preferred PPE from a database of hearing defender products included in the Analyser software package.

For Environmental noise monitoring the Models 93 and 94 provide either an automatic or manual sweep through the filter bands in a measurement duration of as little as 1 minute for the 1:1 Octave Band Filters.

The frequency measurements are automatically time and date stamped with the 1:1 Octave Band Filters, displayed as a bar graph. Comments can then be added to the reports and individual frequency bands can be highlighted using the cursor.
