1.5.4 Pressure Range

The moisture probe always senses the correct water vapor pressure regardless of the total ambient pressure.
The moisture sensor measures water vapor under vacuum or high pressure conditions from as little as a few
microns of Hg to as high as 5000 psi total pressure.
1.5.5 Long-Term Storage & Operational Stability
Sensors are not affected by continuous abrupt humidity changes or damaged by exposure to saturation
conditions even when stored. However, you should store probes in their original shipping containers in a clean,
dry location. If the probe is saturated during storage, refer to "Moisture Condensation" on page 3 before
installing the probe. For best performance, do not store probes longer than one to two years from their
calibration date.

1.5.6 Interference Effects

The sensor is completely unaffected by the presence of a wide variety of gases or organic liquids. Large

concentrations of hydrocarbon gases, Freon , ozone, carbon dioxide, carbon monoxide, and hydrogen have no
effect on sensor water vapor indications. The sensor will operate properly in a multitude of gaseous or
non-conductive liquid environments.

1.5.7 Corrosive Materials

Avoid all materials that are corrosive or otherwise damaging to aluminum or aluminum oxide. These include
strongly acidic or basic materials and primary amines.
