Product Description

The GRAS 146AE is a rugged CCLD microphone set, designed to deliver reliable, accurate measurements in harsh test environments. It combines the high precision and stability of a laboratory microphone under adverse conditions such as shock, high or low temperatures, water spray, oil mists and dust.

The GRAS 146AE is IP67 rated. All exposed parts are protected by water and oil repellent coating, which also is easy to clean. The coating can withstand heat and chemicals.

In addition to the microphone set’s basic resilience against shock, dirt, and moisture a replaceable protective grid with water and dust filter adds an extra layer of flexible protection, including protection against high-velocity particles.

Due to the resilience and exceptional longevity of GRAS 146AE microphone sets they can be left in situ for longer resulting in less downtime and more confidence in measurement results.
