Traceable® Double Display timer allows simultaneous programming of two different activities from 20 hours to 1 second. Each channel has a distinct alarm and display indicator when zero is reached. The alarm may be turned off or silenced automatically after 1 minute. For repetitive timing, a memory recalls a set time. A second display mode shows the time-of-day and a stopwatch for count-up timing. The timer automatically counts up from zero to indicate time since alarming. Large ½ in.-high digits may be read from 10 ft. away. Use it flat or in the flip-open stand position with the clip and magnet. Includes AAA battery, providing 2 years of normal usage. A certificate is provided to indicate instrument traceability to standards provided by the N.I.S.T. Calibrated by an ISO/IEC 17025 calibration laboratory accredited by A2LA.
