Testing of Colorimetric Tubes for Nitrogen Dioxide and Monomethylhydrazine.
Diamond, Philip
Colorimetric tubes for nitrogen dioxide (NO2) and monomethylhydrazine (MMH) were tested for accuracy and results indicate that at the levels checked the tubes' average deviation was plus or minus 20 percent. Tube NO2 concentrations all read lower than the analyzed concentrations. MMH tubes read much higher than the analyzed concentration of 0.28 ppm but averaged +20 percent deviation at the 1 to 2 ppm level. (Author/JR)
