The Perfect Solution of Occupational Noise Measurements
Optimus Red Sound Level Meters
Measuring noise at work doesn't need to be a time-consuming task. The Optimus Red Sound Level Meter uses the very latest digital technology to save you time.
By measuring every parameter you need simultaneously, it can record everything in one measurement. There's no concern about choosing the wrong function or missing any data. All you need to do to get going is switch on, calibrate and start. It's that simple.
All of your measurement data displays on the large OLED screen, so you can see straight away if there are any occupational noise problems in your workplace. You can easily navigate screens to see the data you need during measurements.
Whether you need to meet the UK and EU Regulations, measure to OSHA HC & PEL, MSHA, ACGIH
