It measures oxygen in ten ppm ranges and six percentage ranges. All ranges are user-selectable. This compact transmitter uses proven sensor technology to accurately measure O2 in a variety of gases, even in hazardous environments.

The oxygen.IQ's 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, reduces sources of contamination. The cell is unaffected by other background gases or hydrocarbons and is compatible with acid 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 or electrodes to clean. Intrinsically safe when equipped with optional zener barriers or a galvanic isolator.
