Ionix - Handheld Dissolved Oxygen Meter | Apera DO8500

Results demonstrated excellent correlation between the optical sensor and the Winkler titration method. Optical sensors respond faster than membrane-based sensors to changing temperature and DO. Readings are stable and drift is minimal over long-term deployments. Durable sensing element offers a longer operational life than an oxygen-permeable membrane. Maintenance and calibration requirements are drastically reduced, minimizing site visits and operational costs. Material costs are reduced. Clark-cell sensors require frequent replacement of membranes and filling solution. The optical sensor Cap is replaced annually.
