Acoustic measurements in laminar and turbulent airflow require low-profile microphones to avoid disturbing the sound field. This is why we at GRAS have developed the UTP microphones – Ultra Thin Precision microphones. They combine the advantages of the classical measurement microphone – wide frequency range, accuracy, and repeatability – with an ultra-small form factor. The GRAS 48LX-1 is only 1 mm in height, and therefore it is ideal for measurements in boundary layers and turbulence. Explore the Benefits The very small things which make the BIG difference Quality Data UTP provides accurate data from precision measurement microphones manufactured to narrow specifications. Low Profile With a height of 1 mm the door to a whole new world of what can be measured in boundary layers and turbulent flow opens. Easy Mounting and Verification As shown below, mounting is easy, and once mounted, the setup can easily be verified in-situ. GRAS UTP Microphone 48LX-1 Small Form Factor Can be used in small or difficult-to access spaces where conventional microphones must give up. Cost-saving Solution Easy mounting, CCP interface with integral cabling and in-situ verification all add up to reduced setup time and faster measurements- with reliable data.
