The VisiFerm Optical DO Sensor utilizes luminescent technology and eliminates the typical drawbacks associated with membrane components. The measurement is unaffected by sample fouling and poisoning and is virtually maintenance free as there are no membranes to replace, no electrolyte solution to replenish and no anode or cathode to clean. The VisiFerm also requires infrequent calibration. This sensor utilizes luminescent technology and eliminates the typical drawbacks of membrane components. The measurement is unaffected by sample fouling or poisoning and virtually maintenance free with no membranes to replace, no electrolyte solution to replenish, no anode or cathode to clean or replace and long calibration intervals.
Simplify your dissolved oxygen measurement
Optical sensors measure using an oxygen-sensitive fluorescent dye. The dye requires no equilibration time so it is instantly ready for use. A quality indicator displays the health of the sensor cap, and maintenance is as simple as removing and reinstalling the cap.
Introducing VisiFerm mA
Designed especially for production environments, VisiFerm mA is a simple 2-wire 4-20 mA (HART) installation with ATEX approval that mitigates the negative effects of aging, temperature, and photobleaching. The next generation VisiFerm mA drastically reduce calibration frequency.
