Digital Hourglass offers the simplicity of an hourglass by starting the count down as soon as it is turned over. Unlike a sand hourglass, however, the duration of the count down is adjustable to any interval between 1 second and 100 minutes. As the timer counts down digital sand flows from the upper to the lower part of the hourglass display. The LCD also shows minutes and seconds remaining at the top of the display and minutes and seconds elapsed at the bottom. The flow of the digital sand and the timing sequence reverses each time Digital Hourglass is turned upside down. Upon completion, the original count down setting can be restarted simply by flipping the timer over. Digital Hourglass also operates as a conventional digital timer using buttons on the back. One button cell battery included. N.I.S.T. traceable certificate of compliance available. Dimensions: 1¾” x 4” (45 x 100 mm) Weight: 1½ oz. (43 g).
