VisiFerm mA Optik Çözünmüş Oksijen Sensörü

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.
