The Optimus Red is a vastly upgraded version of the Optimus Yellow and has been specifically built to carry out occupational noise measurements. All Optimus Red variants meet the Noise At Work Regulations.
The Optimus Red sound level meter makes measuring noise at work easy, as it uses the very latest digital technology to save you time. It can measure all the data you need simultaneously, so you won’t need to worry about missing something or choosing the wrong function. Just turn it on, calibrate it, and get measuring!
Built as a noise at work meter, the Optimus Red meets the Noise At Work Regulations in the UK, European Union noise regulations, and OSHA, HC & PEL, MSHA and ACGIH guidelines in the United States. This is the only piece of equipment you need in order to protect your workers from noise-induced hearing loss caused by excessive noise exposure in the workplace.

What our customers say..
There is nothing out there that can rival the Optimus Red noise level meter for its intuitive technology and accuracy
The Optimus enables me to simultaneously get all the noise data I need, assess arising noise issues, make decisions, act on them immediately and record what's happening.
