Fully featured low power industrial PC built directly in the unit
8 multisensor analog inputs (voltage,
bridge, IEPE, temperature)
Simultaneous, 24 bit sigma delta analog to
digital converters
8 counter inputs (counting, waveform
timing, encoder) / 24 digital inputs
2 X CAN bus (vehicle CAN, sensors, OBDII,
J1939)

INSTRUMENTSINSTRUMENTSROBUST
Carbon fiber and aluminum housing
30 GB solid state hard drive (optional 120 GB, 250 GB)
Instrument and PC are sealed in separate chamber
High ambient temperature rating (0-50 deg. C)
Active heating and cooling even increases the temperature rating to -20 to 55 deg. C (optional)
SMALL AND LIGHTWEIGHT
You will never pay overweight anymore on airplane for shipping measurement equipment, Minitaur weights only 1.8 kg. That's probably less weight than your notebook.
Even though it is fully packed with features, it has extremely small size of only 230x78x45 mm, so it fits in any back pack or carrying case making it extremely portable.
GREAT CONNECTIVITY
Minitaur offers great connectivity. 4 USB ports allow the connection of external keyboard, mouse, USB keys for data transfer and additional devices. It has VGA connector for external display.
LAN port also enables the connection to external LAN enabled devices or sensors, which are becoming more and more popular today.

INSTRUMENTSINSTRUMENTSDEWESoft INCLUDED
Each Minitaur includes our award winning software package to measure analog, counter, CAN, GPS, video data and perform virtually any online or offline calculation task.
WIRELESS SYNCHRONIZATION
1 Hz (or 100 Hz) build in GPS allows the precise absolute timestamping of data. With LAN or WLAN access more instruments can be connected in measurement network and acquire data simultaneously.
WIDE RANGE POWER SUPPLY
The DC power supply ranges from 6-36 V, making it extremely useful for in-vehicle use. 6 V ensures stable operation even with firing up the car engine and 36 V upper limit is useful for trucks and airplanes.
For industrial or office applications an external 110/220 V AC power supply is included.
PORTABLE DISPLAY and KEYBOARD
The DS-MINITAUR comes with a portable USB keyboard and optionaly with portable LCD display.
