OxyGuard was founded with the primary objective to create equipment that would provide users with exactly the equipment they needed. The first oxygen probe leaving the OxyGuard facility introduced a new standard in aquaculture. The probe was reliable, accurate, hardwearing, easy-to-use, and had an extensive longevity compared to all other equipment on the market. Equally important, it was affordable for even the small fish farmers! Soon we had the leading position on the world market, a position we continue to hold.
