Hamilton, 243666-252, VisiFerm DO ECS 425 H2

Name: VisiFerm DO ECS 425 H2
Brand: Hamilton
SKU: 243666-252

The VisiFerm DO ECS 425 H2 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. The next generation VisiFerm drastically reduces calibration frequency and has a higher robustness. Learn m
