Abstract:

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.
