BTIS

Breakthrough Indicator for Ductless Hood and Fume Extractor Filters

The Breakthrough (Saturation) Stickers (BTIS) are change indicators for ductless hood and fume extractor filters. They are reliable and cost effect means for protection from exposure to toxic vapors in the work place. They produce bright and vibrant color changes when filters are saturated, hence alerting the user to replace the exhausted filter. The BTIS is available for acidic vapors (e.g. acetic acid, hydrochloric acid, hydrofluoric acid, hydrogen bromide, hydrogen chloride, hydrogen iodide, nitric acid, nitrous acid, sulfur dioxide, trichloroacetic acid, and trifloroacetic acid), aromatic diisocyanates (e.g. toluene 2,4-diisocyanate (2,4-TDI), toluene 2,6-diisocyanate (2,6-TDI) and 4,4'-methylene diphenyl aromatic diisocyanates (MDI), basic vapors (e.g. ammonia, aliphatic amines), chlorine dioxide, halogens, hydrazine, hydrogen sulfide, formaldehyde, halogens, mercurymethyl ketones, acetaldehyde & acrolein, nitrogen dioxide and sulfur dioxide. The indicators are easily attached to the outlet of the filter by removing the bottom adhesive protective liner and placing the BTIS on center area of the filter’s outlet. The indicators are highly sensitive to targeted toxic chemicals with first noticeable color changes appear at or below OSHA permissible exposure limits
