Integrated with ultra-high precision chips for fine detection.


IP-independent fluorescent oxygen sensor membrane technology, greatly improving sensitivity with a minimum detection limit of 0.2 ppb (0.2 µg/L).


Durable fluorescent oxygen sensor membrane life time up to two (2) years.


Suitable for water quality monitoring in power plants (non-nuclear) and metallurgical processes, including low-concentration oxygen monitoring in boiler water and circulating cooling water.


Available in two installation types: G1 thread and PG13.5 flow cell, with flow cells made of 316L stainless steel or transparent acrylic material (optional).
