MINITAURs

Compact all-in-one DAQ instrument

MINITAURs

MINITAURs is fully packed with the latest technology and a perfect compact all-in-one instrument. Based on the SIRIUS dual core ADC technology offers amazing dynamic range of 160 dB. MINITAURs has eight universal analog input channels, eight high-precision counter inputs and 1 CAN port for automotive applications.

MINITAURs compact all-in-one DAQ instrument

Build from a solid block of aluminium, MINITAURs is rugged and compact. With footprint of only 266 x 139 x 109 mm, it is a perfect instrument for mobile and/or air-born applications that requires small but powerfull and reliable data acquisition device. MINITAURs is expandable with battery packs BPi2 and BPi4 and compatible with all other frontends of the SIRIUS instruments.
