About Cirrus Research
Cirrus Research plc develops and manufactures acoustic measurement instruments for occupational, environmental and industrial noise as well as for vibration and air quality monitoring. The product range includes Class 1 sound level meters (Optimus/Optimus+ to IEC 61672-1), wireless noise dosimeters (doseBadge, including the intrinsically safe variant CR:110AIS with ATEX/IECEx/FM/CSA approval), cloud-based long-term noise monitors (Quantum Outdoor/Indoor), nuisance noise recorders (Trojan2/TrojanLITE), noise-activated warning signs, vehicle noise monitors and, in cooperation with South Coast Science, MCERTS-certified air quality monitors (PM1/PM2.5/PM10). At its headquarters in North Yorkshire, the company operates a UKAS-accredited acoustic calibration laboratory (No. 10148, ISO/IEC 17025), which also verifies instruments from other manufacturers against traceable standards. A global network of sales and service locations in Germany, France, China, Australia, Singapore and the USA offers calibration, maintenance, training and leasing. Customers come from industries such as aviation, construction, transport, mining, oil and gas, and occupational safety.
