1.4 Features
The oxy.IQ oxygen sensor is an advanced galvanic fuel cell that provides superior performance, accuracy, stability
and long life. The cell’s innovative design eliminates the potential for negative signal output and reduces sources of
contamination. The different types of cells used with the oxy.IQ are listed in Table 1 below. Refer to Table 6 on page 41
for the concentration ranges for each type of cell.
The cell is unaffected by other background gases or hydrocarbons and is compatible with acidic gases ( OX-2 and
OX-4 cells). Recovery from air at low ppm levels takes just a few minutes. Because the cell is self-contained, minimal
maintenance is required. There is no electrolyte to change and no electrodes to clean. Refer to Appendix E: Cell
Models, for more information on the different cell models compatible with oxy.IQ.
The oxy.IQ offers the following features:
• Two-wire, loop-powered, 4 to 20 mA transmitter
• Display with keypad
• Intrinsically-safe option
• Proven galvanic fuel cell O
