GraLab 171 Universal Timer includes 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. 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.
