Research Stopwatch with Earpiece. This unique timer which allows the timing of a subject without disturbing it. For captive and field research, or in classrooms. Hands free operation allows for freedom of movement. The alarm is audible only through a headphone. The alarm can be set for repetitive intervals of every 0.25 second to every hour. Two 1/100th second displays. Counts up or down to 10 hours. Ideal for multiple and simultaneous processes. In stopwatch mode current lap time shown in upper display, cumulative total in lower one. Memory stores last 8 lap times so there is no need to look away from a test to make notes. In timer mode upper display shows original setting while lower one counts down. Warning alarm sounds at 30 seconds before time elapses and when time has elapsed. Countdown cycles repeat upon completion. 30 second shuttle timer for use during timeouts. Lap counter shows number of laps (up to 99) in stopwatch mode and number of cycles repeated in timer mode. Pacesetter function can be set to beep continually from every 0.25 second to every 30 seconds. Shock resistant, superb hand grip. Includes earpiece and battery. Comes with a N.I.S.T. traceable certificate of compliance. Dimensions: 2Â¾" x 2Â¼" x Â¾" Weight: 2.6 oz.
