Trutest enables fire alarm technicians to measure the sensitivity of installed smoke detectors quickly, accurately, easily, and professionally. A revolutionary product, Trutest not only introduces a smoke test aerosol through the vents of the installed detector to the sensing chamber, but operates using a precision closed loop system – measuring smoke obscuration and feeding back information to a controlling microprocessor.
