High quality data - even when measuring under the most extreme conditions

Modern noise testing can be extremely demanding so you need a tough product to meet your expectations. That’s why GRAS has developed the 146AE - a measurement microphone especially designed to perform under extreme test conditions.

Setting up multichannel measurement systems multiple times a day exposes your equipment to additional shocks and drops. It’s important that your test systems are protected against vibrations, extreme temperatures, high humidity, dust and even oil mist.

To maintain efficient testing you also have to trust that your microphones are ready and working when you roll a vehicle into the test chamber – and confident that your data is accurate when you roll it out again. Re-testing or rescheduling is a costly option.

Our answer is the 146AE - the world’s only measurement microphone set that is shock resistant, waterproof, dust and oil mist resistant and able to withstand high temperatures - all without compromising measurement quality.

Built for extreme conditions

• Shock and drop resistant – limited downtime and higher efficiency
• Water, oil and dust-proof (IP67 Rated) – withstands rain, high humidity and oil mist
• Dust, water and high-speed particle protected with a replaceable grid – change the filter not the microphone
• Can be used at high temperatures (125°C) - ideal for engine compartment measurements, transmissions, exhaust andbrake noise tests
• PowerOn Indicator – efficient control of your measurement setup
• Online data – ensure valid data with access to electronic calibration data for your system software
• Repairable diaphragm – low cost on repairs
