The primary focus in the development of the new ECO-line was placed on the essential functions of the measurement technology.
Pure measurement with a focus on precision, speed and reliability and compact packaging enable an impressive price/performance ratio.
The devices also have impressive ergonomics, dust and water protection according to IP 65/67 and backlit display.
The ECO 531 an intelligent oxygen measuring device for fishery, fish breeding, aquarium, aquaculture and well water measurement applications.
