FOXY is immune to interference from moisture, carbon dioxide, methane and other substances. Electrochemical electrodes are subject to interference from a number of substances and sampling conditions. Electrodes can have a response time of 1-1.5 minutes, depending on temperature. Electrodes have a typical lifetime of just 3 months. FOXY does not consume oxygen, allowing for continuous contact with the sample.
Frequent calibration is unnecessary.
Calibration may be necessary on an hourly basis. Their small size is useful for remote monitoring. What's more, the thin film used in the probe tips consumes no oxygen, allowing for continuous contact with the sample. A fiber optic fluorescence probe with thin film-coated tip. Optional probe overcoat .
