The Simplex 6303-9101-1 is a large-format surface mount LED digital clock and timer built for critical-environment applications. With bright red LED digits displaying hours, minutes, and seconds (HH:MM:SS), the 6303-9101-1 delivers high visibility in operating rooms, laboratories, gymnasiums, airports, and industrial facilities.
