Promising greater accuracy in wind-tunnel applications, the Model 130B40 all-in-one, pre-polarized surface microphone and preamplifier combination is capable of taking measurements in spaces where traditional mics won't fit, like outdoor environments and wind tunnels. Designed using computational fluid dynamics (CFD) modeling, the Model 130B40 claims to significantly reduce the impact of undesired air pressure on the microphone during measurement. Features include a maximum dynamic range allowing measurements up to 142 dB and a 32 dBA low noise floor. Standard on this unit is TEDS v1.0.
