From probe scrubbing to smart sensor cleaning 👏💧

In aquaculture systems, biofouling on sensors can lead to reduced measurement accuracy, increased maintenance time, and higher operational costs.

OxyClean is our automated cleaning solution, designed to reduce fouling at the sensor’s measurement point using controlled bursts of compressed air, oxygen, or water.

- No daily inspection required
- No manual cleaning
- No additional software
- Compatible with the OxyGuard Pacific system
- Can be delivered pre-mounted or retrofitted on most OxyGuard probes

After just three months of operation, sensors equipped with OxyClean remained clean at the tip, which is the critical measurement area, while unprotected areas on the probe showed visible fouling. This supports longer sensor lifespan and stable data quality with minimal manual effort.

Did you know OxyGuard started in a basement back in 1987❓

Our founder, Ebbe Høffner, was on a mission and determined to make oxygen measurement more accessible for the Aquaculture industry.

It all began in his basement, and his first employee was Hans-Christian Kromand, who, btw, is still very active and working with us.
With a passion for innovation, the company quickly grew. We moved to bigger premises in Birkerød and later to our current headquarters in Farum.

Today, OxyGuard is one of the world’s leading suppliers of measuring and monitoring equipment for Aquaculture. We also provide equipment for the environmental, wastewater and energy sectors.
Do you have any fun stories from the good old days?

Did you know❓

Oxygen is one of the six biggest costs in trout and salmon farming, right next to feed? Managing it efficiently can make a huge difference!

Without a monitoring and control system, a fish farm’s annual oxygen consumption is significantly higher than it needs to be.

New data from one of our clients shows that the OxyGuard Pacific system delivers estimated savings of 28% to 32%!
