VisiFerm DO ECS 120 H0
The VisiFerm DO ECS 120 H0 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 ECS (Electrochemical Signal) output can be directly input into controllers and transmitters that accept the traditional nano-amp signal of a polarographic oxygen sensor.
Introducing VisiFerm RS485
The next generation VisiFerm drastically reduces calibration frequency and has a higher robustness. Learn more about the new sensors:
