VisiFerm DO Arc 120 H0

The VisiFerm DO Arc 120 H0 is designed to meet the demanding needs of hygienic applications in the biotechnology, bio pharmaceutical, and food and beverage industry. The VisiFerm DO Arc optical dissolved oxygen sensor offers a simple way to upgrade from traditional polarographic sensors. The sensor measurement principle offers increased accuracy and reduced maintenance while the output provides both 4 - 20mA and Modbus digital outputs.

The next generation VisiFerm drastically reduces calibration frequency and has a higher robustness. Learn more about the new sensors:
