The new modular data recorder compactly offers you a wide range of functions. Due to the small design and the use of rechargeable batteries, you can measure almost anywhere.

The gt⁠-⁠432 series is designed for recording with the Acoustic Camera as well as for measurements with up to 100 sensors.

Measurements can be triggered quickly and easily via the integrated touch display, while the connected PC can be located at another place.

The Modular Data Recorder gt-432 Series

The new data recorder gt-432 series offers you a wide range of options for measuring your sound and vibration signals.

Connect up to 112 channels to gt-432 and record signals with a maximum sampling rate of up to 192 kHz.

Thanks to the modular design, you can adapt the data recorder exactly to your requirements. The entry-level models gt-210 and gt-201 have 24 channels for connecting a microphone array or 24 IEPE sensors.

Fully equipped, the gt-432 offers you a total of 112 channels: 96 microphone or IEPE channels, 12 digital inputs and 4 isolated analog inputs (voltage-supplied or current-supplied).

The integrated display shows you the most important operation parameters of the data recorder.

Run it mobile with two Bosch battery packs or use the power supply.

Parallel operation of multiple arrays is implemented.
