The Model 91 (Class 1) or Model 92 (Class 2) data logging sound meters are the ideal instruments to measure vehicle noise. On these models, the pre-amplifier can be removed from the instrument, connected via a cable and located next to the exhaust in the correct position. This allows the sound level meter to be read from the driver’s seat so the correct engine speed can be set for measuring vehicle exhaust noise.
Both sound meters can also be used for the risk assessment of noise levels providing time history and the measurement of all required parameters needed to comply with the Noise at Work Regulations and EU Directive 2003/10/EC.
Each data logging sound meter has been designed to be easy to use whilst providing the user with the fundamental parameters required to comply with current legislation such as Leq, LEPd and LCPeak.
All sound meters in the Quantifier range are data logging making it easy to transform your noise measurements into informative reports. Our outstanding Pulsar Analyser reporting software package is provided as standard, making the transformation of measurements into informative reports a simple task.
The ‘Analyser’ Sound Level Meter Software package is supplied as standard with the Models 91 & 92 instruments. The instruments can store data in their internal memory and this information can be downloaded and reports created using the exceptional Pulsar ‘Analyser’ download and analysis reporting software.
The Sound Level Meter Software also has a special database of hearing protectors that allows the user, at the click of a button, to have all calculations done for them automatically. A selection of hearing protection is listed and a report can be compiled.
The sound meters can be supplied as part of a complete noise measurement kit, containing all that is required to carry out a noise survey.
Outdoor noise monitoring kits are also available for the Quantifier Range enabling you to protect your meter from the climate and dust.
