We offer a range of prepolarised and 200 V polarised condenser microphones. By virtue of our wide experience in this field, we have become one of the world's major manufacturers of precision measurement microphones. Precision sound measurement with condenser microphones requires correct conditioning of the signal from the microphone. For this purpose we have designed different types of preamplifiers and ICP® preamplifiers. To complete our wide range of instruments, we offer accelerometers, with which it is possible to measure vibration transmission through solids and conduct low-frequency structural noise studies.
