At Protronix, we have been developing and manufacturing air quality sensors since 2001. Our range includes Carbon Dioxide (CO₂) sensors, Relative Humidity sensors, Temperature sensors, VOC sensors, Dust sensors, and more. We are a 100% Czech company with both development and production in the Czech Republic. We have ISO 9001:2016 certification.
Protronix s.r.o. – a trusted Czech supplier of sensors with a long-standing tradition and satisfied customers.
Communication with Protronix is excellent, the offer and technical documentation are great. We really appreciate the easy installation of the sensors and especially the built-in auto-calibration feature, so we do not need to service the sensors during the entire operation.
Our collaboration with Protronix has lasted for several years, and I cannot praise it enough. What pleases me the most is the excellent quality of their sensors and the reliability of their deliveries – even when we occasionally need goods practically overnight, they always accommodate us. We definitely count on Protronix in the future as well.
We have been collaborating with Protronix for six years now and can only recommend the partnership. You can always reach them, receive exactly the goods you ordered, and if the ordered goods happen to be out of stock, you are informed about it before shipping. Even custom production or coating of sensor housings is not a problem.
In 2025, we successfully launched the project “Administrative Building with Radar Tower – ELDIS Pardubice,” within which Protronix s.r.o. supplied us with spatial CO₂ sensors for air conditioning. Communication and delivery of goods were reliable, fast, and of high quality. We also appreciate their ability to flexibly respond to special requests and resolve them quickly to the customer’s satisfaction.
