The Model 170 60-Hour Timer provides precise timing for industrial and laboratory work with minute- and hour-hand settings. With GraLab Timing Devices you get accuracy even at maximum setting, combined with features for ease of use.
Two 3-wire receptacles allow you to automatically switch external appliances with the Model 170 timer. Control one appliance with a switch which can either make or break circuit at zero. The other receptacle is independent of the switch and always breaks the circuit at zero.
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. The buzzer alarms at the end of the timing cycle and can be heard above ambient noise levels.
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" polycarbonate/PET case give you multiple placement choices.
Features a permanent plastic boot over the power and outlet control switches to prevent contamination or corrosion.
Limited one-year warranty.
