The electrode performed admirably even in slightly turbid water, providing stable readings within a reasonable timeframe. It was relatively easy to use, connecting seamlessly to a compatible meter (not included, of course). My initial concerns about needing a long acclimation period were unfounded, as the electrode stabilized fairly quickly after immersion.
However, the setup requires meticulous attention to detail; slight air bubbles or incorrect calibration procedures noticeably impacted accuracy. Also, keep in mind that a compatible meter is a must!
Extended Use & Reliability
After several weeks of rigorous testing, the Thermo Fisher Scientific ORION Dissolved Oxygen Electrode, Thermo Fisher Scientific Scientific 970899WP has proven to be a reliable tool for measuring dissolved oxygen. The epoxy body has held up well, showing no signs of cracking or damage despite repeated exposure to various water conditions.
