  • Weatherproof kits available for semi-permanent outdoor monitoring
  • Calibration certificate included as standard

Description

For Industrial Noise measurement these integrating averaging sound level meters 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.

NR and NC values and curves can also be calculated using the Analyser software.

For Environmental noise monitoring the Models 93 (Class 1) integrating-averaging sound level meters 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. You can then add comments to the reports and highlight individual frequency bands.

Outdoor noise monitoring

Because environmental noise monitoring usually takes place outside, your sound level meter your Quantifier sound level meter can be supplied as part of a complete kit for taking environmental noise measurements and noise surveys. Weatherproof kits can also be provided to turn the sound level meter into a longer-term environmental noise monitoring instrument.
