Optimus Green - Environmental Sound Level Meter

The Optimus Range
Overview Measurement Using It Software Options    
 

The Optimus Green sound level meter is for measuring environmental noise in communities and around the outside of industrial sites.

  • Environmental noise surveys - long term or short term
  • Occupational noise
  • Noise Ordinance and Community noise assessments
  • Mix of industrial and residential
  • 12 year warranty

Measure all, think later - the Optimus range of meters measure all parameters at the same time, so there is no need to spend time figuring out if you have the meter set up correctly before starting a measurement. As well as all the acoustic parameters needed for environmental noise measurement, the Optimus Green also offers:

  • Audio recording
  • Voice tag recording of comments
  • Single range 20 to 140 dB
  • Real-Time Octave Band Filters included
  • Real-Time 1/3 Octave Filters as an option
  • Weatherproof Outdoor Kit available

The Optimus Green sound level meter is available as either Type 1 or Type 2 - the most common for environmental noise measurement and more accurate being Type 1. This meter also has everything needed for occupational noise measurement in line with the OSHA, MSHA, ACGIH and EU regulations, making it ideal for anybody involved in both environmental (outside the factory) and occupational (inside the factory) noise.

There are many features included with this meter that are designed to make the task easier. Functions such as a single measurement range, voice notes and audio recording are included in all Optimus Green meters.

The Green range also includes real-time octave band filters and data logging with software and download cable. They measure A, C and Z frequency weightings simultaneously along with Fast, Slow and Impulse time weightings.

If the meter is to be left unattended in poor weather conditions then the Outdoor Kit should be used to offer protection against the elements. The Outdoor Kit also includes a large rechargeable battery pack for at least seven days of monitoring.

Our Recommendation

Most environmental noise surveys demand the use of a Type 1 Sound Level Meter that can make repeating measurements, such as the 5 minute LAeq and L90 (background noise).

We recommend the Type 1 Optimus Green with Data Logging (order code CR171A ). If there is any noise with a high tonal content, then the 1/3 Octave Band option is recommended (order code CR171B).

All environmental noise regulations demand the use of a Sound Level Calibrator. We recommend the Type 1 Calibrator, order code CR515.
