Timers, Laboratory

Definition : Timers designed to measure the duration of laboratory tests and procedures. These timers typically consist of a mechanical, electrical, or, more frequently, electronic (e.g., quartz oscillator) measuring instrument that may include audible signal generators (e.g., buzzers) to indicate that the time for a particular test or procedure has finished; some timers may provide output signals to control the operation of other laboratory devices. Laboratory timers are frequently traceable to a standard (e.g., National Institute of Standards and Technology [NIST]) and/or are periodically and automatically synchronized to standardized radio signals. Instruments that include from one to many channels are available in a variety of shapes and configurations (e.g., tabletop, wall-mounted, handheld); they can measure many different time intervals simultaneously; some instruments permit the full scheduling of laboratory activities up to several days.
