With its new generations of VisiFerm ^TM and VisiTrace ^TM  , Hamilton Bonaduz AG has launched two product innovations for reliable optical measurement of dissolved oxygen. The new generation of VisiFerm ^TM sensors features new electronics, which ensure an 80% reduction in calibration frequency, 50% higher robustness, and supply security for the next decade. “The basis of the innovation is our proven VisiFerm sensor series, which we have continuously improved since it’s market launch 15 years ago,” explains Christian Adank, Product Manager at Hamilton Bonaduz AG. He adds “The meticulous control of dissolved oxygen still requires frequent calibrations to avoid deviations in GMP/FDA requirements. As part of the new sensor launch, significant breakthroughs have been made in the sensor and cap design, that drastically reduce the required calibration frequency.

VisiFerm ^TM is one of the first optical oxygen sensors with integrated optoelectronics that has the full functionality of a self-diagnostic probe. It is autoclavable as well as SIP / CIP compatible. In addition, the sensor requires less maintenance than an amperometric oxygen sensor because it has neither a sensitive membrane nor does it contain a liquid electrolyte. In addition, VisiFerm ^TM provides instant stable values, low drift and a fast response time. Pre-calibration can take place very conveniently in the laboratory, as data is stored directly in the sensor head. "While VisiFerm ^TM is predestined for dissolved oxygen measurements in the biopharma sector, VisiTrace ^TM   was specifically designed for trace measurements of very few particles. Therefore, the latter is an important quality assurance tool especially for breweries. Due to our intelligent and automated measurement, we have equipped both sensors with Arc technology so that data can be transferred quickly and viewed easily using the Arc Air app."
