LPL ET-500 used with my Valoy II for some 5 years. After going through about 5 timers in the last 40 years the ET-500 finally meets all my needs. Foot switch is mandatory for my way of working. LED display, brightness control, audible count down (on/off), times 0.1 to 99.9s or 1 to 999s, enlarger and safelight outlets and relatively small size for my limited space. Available as 220-240V 50/60hz. Timer can be turned off mid cycle with foot switch - handy during burns.
