The GraLab Model 171 60-Minute Timer provides precise timing for industrial and laboratory work with second- and minute-hand settings. 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 Model 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.
