The CH93 series CHRONOS Digital Clocks are a multifunction clock which displays volts, temperature, time, countdown time, and stopwatch, and also comes available with multiple USB charging options. The CH93 installs in to a 2-1/4 inch avionics panel cutout and power is drawn from the aircraft main bus to power the unit. The white, seven-segment LED clock can displays several modes: local time, universal time, flight timers, elapsed and countdown timers and optionally, bus voltage and up to two temperature inputs. The daylight readable display features two methods of brightness controls: automatically using the internal photocell or manually with external dimming bus voltage. An internal battery maintains clock time and flight timer memory when the aircraft is not in use.
This CH93 digital clock (EDMO# 6420093-5) features USB-A and USB-C charging ports, Local Time, UTC/Zulu Time, Flight Timer, Countdown Timer, Stopwatch, Volts, OAT, Secondary Air Temp.
