Description
Gastec detector tube No. 11L measures nitrogen oxides (NO + NO2) in air from 0.03 to 14 ppm. Break both tips off the tube, fit it to a Gastec GV-100 or GV-110 hand pump and draw the number of pump strokes listed for the expected range. The reagent changes from white to yellowish orange, and the stain shows the gas concentration. Read the concentration directly on the scale printed on the tube. 10 tubes per box give 10 tests.
Nitrogen oxides come from combustion, diesel exhaust, welding and cutting, and from some chemical processes. A tube gives a spot reading and does not replace a certified gas monitor where your site procedure requires one. Use only Gastec tubes with a Gastec pump, break the tips away from your eyes, and never handle broken glass or reagent with bare hands.
