To celebrate GRAS 30th anniversary, you can now get the GRAS 146AE ruggedized measurement and GRAS 46AE Industry standard microphone at 30 % off.
The 146AE to ensure that it can perform under real life conditions – and beyond – we’ve developed the gruelling testing standard HALT, consisting of four different types of stress tests:
A temperature stress test at constant and cyclic temperatures; a humidity stress test; a vibration stress test; and a mechanical impulsive stress test.
These severe tests mean you can expect reliable, repeatable, and accurate data acquisition in all tough test scenarios, minimal production downtime, and ultimately minimal need for replacement. Or in other words – low cost of ownership combined with high performance.
The 46AE is a free-field microphone set and as such optimized for all acoustic applications, where the location of the main sound source is known and the microphone can be pointed directly at it ensuring 0° incidence.
The wide frequency range makes it ideal for general acoustic diagnostics. 46AE conforms with IEC 61094 WS2F and IEC 61672 Class 1.
Regarding temperature range, see the Specifications. Should higher temperature limits be required, we recommend the GRAS 146AE 1/2″ CCP Free-field Rugged Microphone Set which can be used up to 125 °C.
A front-vented version is available, 46AE-FV 1/2″ CCP Free-field Front Vented Microphone Set.
