varioLAB
Stationary Data Acquisition System for Physiological Data
As a stationary amplifier, the varioLAB meets all requirements for measuring different electrical biosignals. GSR, ECG, pulse, respiration, and EEG with up to 16 channels can be measured simultaneously and in combination. The varioLAB is particularly suitable in combination with Tobii remote eye tracker products.

varioport-e
Recorder for physiological and environmental data
varioport-e
The newest and smallest product in the varioport family is comparable to its larger counterparts in performance and quality. With dimensions of 65 mm x 43 mm and a weight of only 50 g, it is particularly well suited to environments where authenticity is important and extensive technical equipment would disturb the experiment, for example in supermarkets or at fairs and exhibitions. This unit is also an ideal choice for studying sports activities.
Especially in combination with the Tobii Glasses 2, this solution enables an authentic implementation, since the measuring devices no longer disturb subjects after a short familiarization period.
TECHNICAL DATA
- Dimensions: 65 x 43 x 17 mm
- Weight: 50 grams (including memory card and batteries)
- Channels:
- 8 analog inputs
- Digital marker input
- Channel for battery voltage + power consumption
- Built-in preamplifiers for ECG and EDA
- Built-in 3D sensor for position and movement measurement
- A/D Conversion:
- Resolution: 16 bits (65536 steps)
- Sample rate individually selectable per channel
- Storage Media: MicroSD card (up to 4 GB)
- Power Supply:
- Built-in lithium polymer battery
- Power consumption from 60 µA (standby)
to 1,550 µA (full measurement)
- Operating Time:
- up to 14 days for standard measurements
- up to 50 days (only temperature and humidity)
- Connections:
- Serial interface (start/stop/online)
- USB (battery charging/data reading)
- Two freely assignable input sockets for measuring cables and sensors
