GraLab 171R Mechanical Darkroom Time
Description
Series 170 Universal Timer includes four individual models with precise timing for industrial and laboratory work. With GraLab Timing Devices you get accuracy even at maximum setting, combined with features for ease of use. Two grounded outlets allow you to automatically switch external appliances with the 171 timer.
Control one appliance with a switch which will turn it off or on when time elapses. The other outlet will always turn off when time elapses independent of the switch.
Large numerals on a 6 1/2" face are easy to read. An outer ring tells you elapsed time, while the inner circle can be used as a stop clock. Variable volume control allows you to adjust the buzzer alarm so it can be heard above ambient noise levels or quieter if needed.
Rubber base pads, wall mounting keyholes and a recessed hand grip on the sturdy 7 1/2" x 7 1/2" x 2 1/2" plastic case give you multiple placement choices.
