Our range of Sound Level Meters and Noise Meters spans simple instruments that provide the measurement of Sound Level, Integrating-Averaging instruments that provide Leq and occupational noise functions as well as precision data logging sound level meters with 1:1 & 1:3 real time octave band filters and in-measurement audio recording.
The Optimus Sound Level Meters use the very latest technology to provide instruments that are simple to use whilst giving you the measurement information that you need to make an effective noise measurement.
All of our sound level meters and noise meters can be supplied as a complete measurement kit which includes all of the options and accessories needed. The Optimus Green sound level meters can be used with an outdoor measurement kit which provides weather protection for the instrument and microphone, allowing measurements to be made over long periods outdoors.
The Optimus yellow instruments are a range of state-of-the-art sound level meters that have been designed to meet the very latest standards for noise measurement instruments.
It has been purposed-designed for applications where only basic noise data is required, such as Sound Level (SPL) or Maximum Sound Level (Lmax). These applications include fire alarm testing, machinery servicing and noise ordinance enforcement.
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.

Get the basic noise data you need quickly and with no gimmicks
The CR:308/310 is a basic sound level meter that is perfect when you need basic noise information, capable of measuring the maximum sound level (LMax) and the sound pressure level (SPL).
The Cirrus CR:308/310 sound level meters provide an entry level for noise measurement across multiple sectors, and meets current international standards for noise measurement instrumentation.
Both variants provide the SPL and LMax readings, which can help you determine how loud something/somewhere is without overcomplicating the data with other acoustic information. Both variations can also measure different frequency weightings, which provides more detailed and accurate data than many other basic sound level meters on the market.
The CR:308 displays the SPL and LMax data, and comes with the ability to set your own noise level alert. Simply choose a decibel level, and when the meter records a noise level that meets or exceeds your pre-set value, a indicator will appear on the screen. This is incredibly useful when you need to know quickly and easily whether or not something is louder than a prescribed value.
