varioLAB
Stationary Data Acquisition System for Physiological Data
As stationary amplifier the Variolab meets all requirements for the measurement of different electrical biodata. GSR, ECG, pulse. Respiration and EEG up to 16 channels at the same time can also be measured in combination. The Variolab is particularly suitable in combination with the remote eye tracker products from Tobii.

varioport-e
Recorder für Physiologie- und Umweltdaten
varioport_e
The newest and smallest product of the Varioport-family, but indeed comparable to its bigger brothers in performance and quality. With its dimensions of 65mm x 43mm and a weight of only 50g it is particularly well suited for use in environments where it comes to authenticity and where extensive technical equipment would constitute a disturbance of the experiment, for example in supermarkets or at fairs and exhibitions. Also the field of study of sports activities this unit is an ideal choice.
Especially in combination with the Tobii Glasses 2 this solution guarantees optimal authentic implementation, since the measuring devices do not disturb the subjects after a short time of getting used to them.
