For Occupational Noise and Industrial Hygiene, measuring the noise exposure of employees quickly and reliably is essential. The optimus red sound level meters are the ideal instrument for these applications with a clear, high resolution OLED colour screen, a wide 120dB measurement span (up to 140dB(A) and 143dBC Peak) and simultaneous measurement of all available parameters. There’s no setup or complicated configuration needed. Just switch on, calibrate and press start. It’s that simple.

VoiceTag audio recording

Before each measurement is made, you can record a VoiceTag by simply speaking into the microphone.
You can record notes about the measurement location, describe what is being measured or simply store information that may be useful at a later date.

The ideal instrument for any application

With two additional “virtual” noise meters running at the same time, you can meet any noise regulation, guideline or standard.
Whether you need to meet the UK and EU Regulations, measure to OSHA HC & PEL, MSHA, ACGIH or any other regulation, an optimus red is the ideal instrument.
 

Simple operation with advanced technology

The optimus sound level meters have been designed with ease of use as the most important feature which lets you get on with measuring and controlling the noise.

The instruments use the very latest in digital technology and industrial design techniques to make everything as clear and simple as possible.

The high resolution colour OLED screen can be seen in any conditions, and the keypad illuminates automatically in low light.

The case is robust and covered with a tactile finish so it can be used even if you’re wearing gloves.

The measurement data is displayed in a clear and simple format along with a realtime noise chart so that you can see how the noise varies with time.

All of the functions of the instrument are measured simultaneously, and with a wide 120dB measurement span you don’t need to worry about choosing the right range. An optimus can measure up to 140dB(A) and 143dB(C) Peak in this single range.

Just switch on, calibrate and you are ready to go.

The ideal solution for occupational noise

NoiseTools Software

The NoiseTools software package gives you a quick and simple way to download, analyse and report your noise measurement information.

The initial summary screen shows you the most commonly used information and, through simple icons, gives you access to the detailed measurement data. You can simply print the summary screen to get a quick measurement report.

For advanced users, each and every function measured by the instrument is available for review and analysis and the data can be exported for further use.

VoiceTag audio recordings can be played back for reference and are automatically stored with the measurement data. Where Octave Band data is available, this information can be used by the program to calculate the level of protection from a range of hearing defenders and ear plugs.

To help you keep your noise measurement data organised and easy to find, NoiseTools allows each measurement to be allocated to people, places and projects.

Measurements can be sorted or grouped by any parameter, person, place or project and measurement reports created quickly and easily.

NoiseTools is supplied free from any licensing restrictions or limits allowing you to install the program on as many PC’s as needed at no additional cost.
