VisiFerm mA Dissolved Oxygen Sensors

Precise DO Measurement,
Less Frequent Calibration
Hamilton extensively investigated the effects of the bioprocess on measurement accuracy. Analysis of sensor aging, chemical attack, and physical damage yielded the necessary understanding for development of a next generation VisiFerm which reduces the need for frequent calibration.

What is the expected lifetime and when should I replace my ODO cap?
ODO cap health is process specific, with a cap quality indicator in ArcAir representing the general health of the ODO cap. ODO cap quality replacement is advised at 35%, however, some customers may replace ODO caps as part of a preventative maintenance program before reaching 35%. Click to learn more. -
Can I use a VisiFerm, VisiPro, or VisiTrace for gas phase oxygen measurements?
Yes. Optical DO sensors can be used for monitoring oxygen contents in air as well as dissolved oxygen. -
Does temperature impact my oxygen measurement?
Yes, in a closed system, gas phase temperature is directly proportional to pressure and therefore measured oxygen content. In solution, temperature is inversely proportional to dissolved oxygen content.

Firmware Updates for Arc Products
Hamilton Arc and VisiFerm ECS sensors rely upon internal firmware for their operation. Periodic firmware updates ensure that the sensor has the latest features and fixes any pre-existing bugs that may exist. -
Comparing Optical To Polarographic Dissolved Oxygen Measurement
There is a clear trend in the market towards replacing polarographic with optical dissolved oxygen. When evaluating the switch to optical, engineers must consider if there will be any impact on the current process due to the change in measurement principle. -
Optical Dissolved Oxygen Sensor Caps
There are several different options for optical dissolved oxygen (ODO) caps. This article provides recommendations for each product.
