optimus red for occupational noise

CR:161C optimus red sound level meter for noise at work

CR:161C optimus red sound level meter for noise at work

The optimus red sound level meters use the very latest digital technology and industrial design to give you the ideal instrument for Occupational and Industrial Hygiene noise measurements.

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 VoiceTag recordings are downloaded with the noise measurement data and can be played back from within the NoiseTools software.

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.

Instrument Versions

The optimus red comprises the A, B, C and D variants, each of which can be specified as either Class 1 or Class 2. All of the instruments can measure Sound Level functions plus Lmax and Lmin with all frequency and time weightings.

  • The A versions measure the Integrated noise levels such as Leq and LAE, C-A, Peak Sound Pressure and the virtual noise meters for OSHA/MSHA/ACGIH.
  • The B versions provide the same functions as above but with the addition of Data Logging so that measurements can be downloaded to the NoiseTools software. The VoiceTag audio recording is available on the B versions.
  • The C versions add Real Time Octave Band Filters to the functions of the B versions which can be used for the selection of hearing protection.
  • The D variants add NR & NC values and curves directly on the instrument display.
