This electric, 60-minute general-purpose device provides precise timing with second- and minute-hand settings.

• Elapsed time indicator (up counter) and interval timer (down counter)
• Two switchable outlets; turn loads on or off
• Split-second accuracy
• Power switch starts the timing cycle
• End of cycle buzzer is adjustable from 0 to 80 dB
• Equipped with wall mounting keyholes and recessed hand grip

The large numerals on the 165 mm (6¹/₂") display are easy to read, and the buzzer alarms at the end of the timing cycle can be heard above ambient noise levels. Two grounded outlets allow automatic switching between 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.
