iSV1611-Infra
The first class 1 WS2F-compliant infrasonic measurement microphone with USB interface on the market.
It is equipped with a pre-polarized 1/2” microphone capsule that has been specially developed for low-frequency applications and works in a linear range from 1 Hz to 20 kHz.
The iSV1611 USB microphone preamplifier is able to perform measurements in two different level ranges simultaneously.
The measurement of infrasound is possible with very low ambient noise from a level of 15 dBA.
The USB microphone preamplifier is designed for three different sampling rates: 48 kHz, 96 kHz and 192 kHz.
This allows the iSV1611 digital preamplifier to be combined with other microphone capsules, e.g. for ultrasound or high-level measurements.
- Frequency range 1 Hz to 20 kHz
- Free Field
- Measuring range 15 dB(A) to 135 dB
