The standard Optimus+ Industrial Sound Level Meter is capable of measuring the maximum noise level during a session, and provides simple and easy-to-understand data, including frequency weightings and time history.

Most suited for applications where only basic noise level data is required, these models can record the sound pressure level (SPL), maximum sound level (LMax) in decibels, which refers to the loudest recorded noise level during a period of data capturing, and on specific variants, allows for data logging of the sound levels measured over a user-defined period of time. This data will give you a basic understanding of the noise levels where you are measuring, and will allow you to identify any particular noise hotspots.

The Optimus+ Industrial Sound Level Meter with Leq Values makes noise level measurements incredibly easy and straightforward, saving you time while capturing all essential noise level data simultaneously. This instrument captures sound pressure level (SPL), time weighted and frequency weighted values at the press of a single button.

By measuring every parameter simultaneously, you can be sure that your occupational noise survey will be comprehensive and robust, providing the level of detail required for making better-informed decisions and reporting to key stakeholders within your organisation.

Sometimes it’s not possible to hold the meter whilst taking measurements, this might be due to location, the noise level itself, or the length of time you want to measure for. The Optimus+ Industrial range includes Bluetooth connectivity to help solve this; with the addition of the dBActive smartphone app, you can easily operate your sound level meter from a short distance away.

Each of our data logging Optimus+ Sound Level Meters feature VoiceTag audio note recording, increasing the ease with which your NoiseTools database can be organised. Before each measurement, simply speak into the microphone to provide additional information such as the location of your reading. Once your measurement data is downloaded to NoiseTools, these audio notes are automatically converted into text.

The Optimus+ Industrial Sound Level Meter with Leq Values and with Octave Bands both have LNE Pattern Approval. See the Downloads tab for our certificate. Pattern Approval is a method where a test laboratory such as the LNE tests an instrument against a set of standard tests to ensure that it meets the performance claims of the manufacturer.
