COLUMBIA's Models 765M25 and 765M27 are High Intensity Acoustic Sensors (Microphones) designed for measurement of gas-borne sound in frequency range of 100Hz to 30KHz, in industrial applications requiring operation up to +500 degrees F. (read more)

The Columbia Model 100-P High Intensity Acoustic Sensor (Microphone) is designed for measuring exceptionally wide pressure ranges in applications requiring fast rise times and broad frequency response. This sensor is extremely sensitive allowing very low pressure measurements to 0.005 psi as well as high pressure transient measurements to 5,000 psi at temperatures up to +150 Degrees C.

PCB Model HT378B02 is designed to overcome high temperature testing challenges associated with acoustic measurements in environmental chambers or other high temperature applications. (read more)
