‘Don’t take a stab in the dark’ when choosing tools for testing smoke, heat and carbon monoxide. Some claim a new technology; however the professional knows the 1490 Aerosol Adapter has been available since 1994. Preferred world-wide by technicians, AHJ and Fire Marshalls, the 1490 has been UL listed, patented and available for over a decade.

HSI Fire & Safety Group suggest you team their 1490 Aerosol Adapter with their 25S Smoke Check™; the original aerosol tester, UL listed and patented since 1979.
So ‘don’t take a stab in the dark’, choose the original – choose Versa-Tools™ professional line of detector testing tools and Smoke Check, the original aerosol detector tester.
