PortaLite mini

Measures local tissue saturation (TSI), as well as oxy-, deoxy- and total hemoglobin.


The PortaLite mini is ideally suited for brain measurements during everyday activity. The small and flexible probe is easy to attach and connected with one wire to the portable battery housing. The PortaLite is easily applicable and could be seen as one of the smallest and most portable brain oxygenation monitoring devices on the market. 
The PortaLite mini has three light sources and is therefore capable of measuring tissue saturation index (TSI), which is an absolute measure of oxygenated hemoglobin. Furthermore, this NIRS system uses near infrared spectroscopy (NIRS) to measure oxy-, deoxy-, and total hemoglobin concentrations at capillary level in a non-invasive way. 


  • Non-invasive
  • Light, easy and portable
  • In the lab and in the field
  • Measure continuously
  • Affordable
  • Without the need for special infrastructure
  • Without specially trained personnel

Applications & user research

The PortaLite mini is an easy to use and truly portable oxygenation monotoring device. You are enabled to create online measurements using bluetooth or offline measurements through on board data collection. This makes it a perfect device for measurements both in the lab and in the field. 
The PortaLite mini has a flexible sensor to fit the curvature of the head, or smaller muscles like the intercostal or trapezius muscle to offer even more possibilities. For prefrontal single channel measurements, brain oxygenation can also be studied a lot easier with the PortaLite than with the big and non-portable NIRS systems. For example, the PortaLite has been utilised by our customers during dual tasking (Maidan 2015) and to detect epileptic seizures (Jeppesen 2014).

NIRS - add ons

Would you like more than 1 NIRS device? You can measure with multiple (different) Artinis NIRS devices at the same time. All data is synchronised and stored in one datafile. We also offer NIRS EEG packages.

PortaLite accessories

All of our NIRS devices can be combined with the PortaSync. It is a handheld device for synchronisation of the different types of instrumentation and the data files they produce.
