5.) Excessive water vapor (i.e., >3 mg/l of H
2
O) may cause the reagent in the oil mist
tube (PN 109AD) to stain yellow although the reading will not be affected. Run
the water vapor test before running the oil mist test. The recommended testing
priority is listed below.

6.) The proper stain color for oil mist tube is dark brown. Other color changes
should be disregarded.
7.) Moisture intrusion in the oil mist tube (PN 109AD) causes a bleaching of the
reagent (see #5 above). If a stain is obtained on oil mist tube and a bleaching has
occurred around the zero, read the stain and ignore the bleaching.
8.) The H20 tube (PN 6A) responds to water vapor with either a green or a purple
Stain. The green color merely signifies the presence of water vapor. It is not
related to the concentration and should be ignored. Read only the purple stain.
9.) The reading on the H2O tube should be recorded immediately. When the tube is
removed it will continue to respond to ambient moisture. Similarly, place the
tube in the holder as soon as possible after the ends have been broken.
10.) Always pay strict attention to the instruction sheets provided in the tube boxes.
Detector tubes have limits on temperature and humidity.
11.) Accuracy in detector tube testing is
±25%
