The Cirrus Optimus Green handheld noise meter effectively assesses environmental noise impact over long and short periods of time, with an abundance of features available for operators. The essential piece of equipment for measuring and monitoring exposure to noise pollution and environmental noise sources.

All noise parameters are measured as one by the instrument, eliminating risks of selecting the incorrect settings and not measuring essential information. The Cirrus Optimus Green CR:171B has a comprehensive measurement capability. Equipped with a wide measurement range of 120dB whilst providing a complete picture of noise under investigation, as the overall Leq, LMax and statistical Ln% values are measured along with a range of noise profiles.

Results are presented on a high-resolution colour screen with a low light detector to illuminate the keyboard; the data is displayed in a clear and simple format along with real-time noise presented in a chart. Simultaneously, CR:171B measurements and data logger parameters are recorded and saved for later analysis.
