This dissolved-oxygen sensor avoids bubble-induced errors
Broadley-James
The OptaProbe (photo) is a smart optical dissolved-oxygen (DO) sensor for use in bioprocess applications with autoclave or steam-in-place (SIP) requirements. OptaProbe sensors feature this company’s DeflectorCap with a 45-deg angled sensing surface, which deflects sparge bubbles in any insertion orientation and SpargeSafe firmware, which eliminates bubble errors. The OptaProbe has a sophisticated, built-in signal-filter system that recognizes measurement noise caused by bubbles and filters it out of the signal. This significantly increases measurement precision in challenging bubble-filled aeration environments. Measurement errors caused by bubbles striking the measurement surface are drastically reduced and in many cases eliminated.
