Engineered for easy insertion into the Allegro 2050 Smoke Test Kit, these tubes emit a visible irritant smoke to detect leaks and confirm proper respirator fit, ensuring workplace safety and regulatory compliance. Trusted by professionals since 1987, these cost-effective refills keep your fit testing program running smoothly without the need for full kit replacements. ## Description When activated, Stannic Chloride is a white colorless gas with a pungent odor. It fumes strongly in moist air forming white hydrochloric acid fume. The emitted tin compound has a strong odor that will provoke an involuntary reaction (i.e. coughing) by the test subject. Review: Fit Test revealed - Have used this product many years no issues with testing. Review: Great Product, Easy to Use - In my opinion, these are the best option for fit testing. Stop those that try to sneak under the radar, there’s absolutely no way to fake it with the irritant smoke. ## Features - π—₯π—˜π—£π—Ÿπ—”π—–π—˜π— π—˜π—‘π—§ π—¦π— π—’π—žπ—˜ π—§π—¨π—•π—˜π—¦ 𝗙𝗒π—₯ π—™π—œπ—§ π—§π—˜π—¦π—§π—œπ—‘π—š – Designed for use with the Allegro 2050 Standard Smoke Test Kit to conduct OSHA-compliant qualitative respirator fit check - 𝟲 π—§π—¨π—•π—˜π—¦ π—ͺπ—œπ—§π—› 𝗖𝗔𝗣𝗦 π—œπ—‘π—–π—Ÿπ—¨π——π—˜π—— – Each pack contains 6 stannic chloride smoke tubes plus 2 protective rubber caps for safe storage and handling between uses - 𝗒𝗦𝗛𝗔-π—–π—’π— π—£π—Ÿπ—œπ—”π—‘π—§ π—€π—¨π—”π—Ÿπ—œπ—§π—”π—§π—œπ—©π—˜ π—§π—˜π—¦π—§π—œπ—‘π—š – Produces a visible irritant smoke used to identify leaks and confirm proper respirator fit during mandated fit test procedures - π—˜π—”π—¦π—¬ 𝗧𝗒 π—œπ—‘π—¦π—§π—”π—Ÿπ—Ÿ & π—¨π—¦π—˜ – Simply insert into the aspirator assembly included with the Allegro 2050 kit for immediate testing capability - 𝗖𝗒𝗦𝗧-π—˜π—™π—™π—˜π—–π—§π—œπ—©π—˜ π—₯π—˜π—™π—œπ—Ÿπ—Ÿπ—¦ – Keep your testing program running without buying a full kit; economical solution for ongoing safety and compliance needs - 𝗧π—₯π—¨π—¦π—§π—˜π—— 𝗕𝗬 π—œπ—‘π——π—¨π—¦π—§π—₯𝗬 𝗣π—₯𝗒𝗦 π—¦π—œπ—‘π—–π—˜ 𝟭𝟡𝟴𝟳 – Manufactured by Allegro Industries, a leading name in industrial safety and ventilation equipment for over 35 years.
