PROTRONIX Ltd. (s.r.o.)

We started with the brain (control electronics) for the ventilation units. We also not only needed to control the ventilation, but also to somehow measure the air quality and ventilate accordingly. So we started to develop the first CO2 and relative humidity sensors. We contended with the accuracy and stability of measurement in the first sensors. Today, we can offer you sensors that will serve you well for over 10 years!
