Class 1 Sound Level Meter for Noise Consultants – Safety & Environmental

Castle dBAir-SE (With Octave Band Option)

£3,201.50 excl. tax | £3,841.80 incl. tax

The Castle dBAir Safety & Environmental Class 1 (with the option of Octaves) sound level meter is a specialised instrument used for precise sound measurement, particularly in environments where accurate noise monitoring is crucial.
As a Class 1 device, it offers the highest level of accuracy according to international standards (IEC 61672-1). This is essential for environments where precise noise monitoring is required, such as in environmental assessments, occupational health and safety evaluations, and industrial noise monitoring.
The inclusion of Octave Band Analysis allows for the detailed analysis of noise across different frequency bands. This is vital for identifying specific sources of noise and assessing their impact, which is important in situations where particular frequency ranges are more harmful or subject to stricter regulation.
The meter is ideal for monitoring workplace noise to ensure compliance with safety regulations, assessing noise exposure, and implementing noise control measures. It’s also suited for environmental noise assessments to ensure compliance with local noise ordinances or planning conditions.
Control of Noise at Work Regulations 2005 requires employers to prevent or reduce risks to health and safety from exposure to noise at work. The dBAir helps in assessing noise levels to ensure they are within the legal limits.
Environmental Protection Act 1990 includes noise as a statutory nuisance. The meter can be used to measure environmental noise to determine if it constitutes a nuisance under this act.
  • Designed for the Control of Noise at Work Regulations 2005 and noise assessments to BS4142 (Complaints about industry) and BS5228 (Construction Noise)
  • Supplied with a noise at work assessments template to make your job as easy as possible
  • Supports optional Octave Bands for Hearing Protection selection
