Measuring noise at work doesn't need to be a time-consuming task. The Optimus+ Red noise at work sound level meter makes noise level measurements incredibly easy and straightfoward, as it uses advanced digital acoustic technology to save you time while capturing all essential noise level data simultaneously. The instrument captures sound pressure level (SPL), time weighted and frequency weighted values, and octave band data at the press of a single button. You'll never need to worry about missing something or choosing the wrong function: just turn it on, calibrate it, and get measuring! By measuring every parameter you need simultaneously, you can be sure that your occupational noise survey will be comprehensive and robust, providing the level of detail required for making better-informed decisions and reporting to key stakeholders within your organisation.

The Optimus+ Yellow is a range of basic sound level meters built to international standards (IEC 61672) and available as either Class 1 or Class 2 sound level meters. The range is the entry-point for Cirrus Research's well-renowned Optimus+ range. The Optimus+ Yellow noise level meter is capable of measuring the maximum noise level during a session, and provides simple and easy-to-understand data, including frequency weightings and time history. The Optimus+ Yellow is a state-of-the-art noise level meter that has been designed by the engineers at Cirrus Research to meet the very latest international standards in sound measuring and monitoring.

The top-of-the-range Optimus+ Green has been specifically designed as an environmental noise meter and is perfect for measuring and monitoring exposure to noise pollution and environmental noise sources, including construction sites, windfarms and industrial operations. Available as either a Class 2 or Class 1 sound level meter, built to IEC 61672, the Optimus+ Green environmental noise meter provides everything you need to measure both occupational and environmental noise, to the fullest extent. Capturing the full range of sound parameters simultaneously, there’s no other noise measuring instrument you need to measure and monitor exposure to environmental noise.

We’re proud to announce the launch of the new GPS-enabled Optimus+ sound level meter, designed to make environmental noise monitoring easier and more effective than ever before. The Optimus+ GPS builds on the incredible technology of Cirrus’ iconic Optimus range, by providing highly accurate location data for every measurement that’s taken. Optimus+ GPS automatically stores location data with each reading, which can be analysed in our licence-free data reporting software, NoiseTools. There’s no need to purchase a whole new noise measurement instrument to benefit from the GPS functionality, you can simply purchase the module and add it to your existing Optimus+ Red or Green device. It’s also available as a full sound level meter kit. With optimised battery life, the Optimus+ GPS is perfect for taking environmental noise measurements. The industry-leading time to first fix means that it is easier and faster than ever before to connect the module to a GPS signal.
