Definition : Timers designed to measure the active length of time of an exposure during a phototherapy treatment. These timers typically consist of an appropriate light detector for sensing light at the same frequency of the light source (e.g., visible, ultraviolet, infrared), an electronic time-measuring instrument, and a display; the timers are usually battery-operated instruments. Phototherapy timers are typically dedicated instruments intended for use attached to a particular source of therapeutic light; they are usually an integral part of the phototherapy unit, frequently attached to the control system. Phototherapy timers are also used for inspection and/or calibration of phototherapy units.
