Aerospace applications – emission control devices. Chemteq manufactures area monitors as well as filter change indicators and filters with end-of-service life indicators. Applications include hydrazines, MIL-87930, H-70 and nitrogen dioxide. These filter change indicators include the BTI (3.5” length, 1” diameter and 0.75” MNPT inlet).

Our BTI Inline has dimensions of 3.5” length, 1” diameter and 0.75” MNPT inlet and outlet. The BTI with auxiliary filter trap (5.1” length, 1” diameter and 0.75” MNPT inlet) is most suited for highly toxic substances such as hydrazines. BTI 2 (4.5” length, 2” diameter and 1.5” MNPT inlet), and BTI 3 (4.5” length, 3” diameter and 2.5” MNPT inlet) are suitable for large drum-type filters.

BTIS are filter change indicators stickers for ductless hood filters, the BTIS B are leak detectors suitable for chemical cabinets and chemical transport vehicles . We also manufacture three different sizes of filters with end-of-service life indicators for hydrazines, MIL-87930, H-70 and nitrogen dioxide.

Custom cut colorimetric indicators are available for wide range of chemicals including hydrazines, MIL-87930, H-70 and nitrogen dioxide.

Our indicators have shelf-life range between one year and two years, plus service life range between one year and two years. Sun light has no effect on the hydrazine indicators and they are waterproof.

Facts about hydrazine

Hydrazines (H₂NNH₂) are clear, colorless liquids with an ammonia-like odor. Hydrazines are highly reactive and easily catch fire. The level of harm to workers from hydrazine depends upon the dose, duration, and work being done.

Hydrazine is used in many industries, such as the manufacturing of rocket propellants and fuels for spacecraft. Some examples of workers at risk of exposure to hydrazine include the following:

  • Workers who use it for boiler water treatments to protect against corrosion
  • Industrial workers who use it as a chemical reactant
  • Researchers who explore cancer treatments
  • Agricultural workers who use it in pesticides
