GraLab Model 170 60-Hour Timer

The GraLab Model 170 60-Hour Timer offers precise timing for industrial and laboratory work with minute- and hour-hand settings. Two 3-wire receptacles enable you to automatically switch external appliances. Control one appliance with a switch that can either make or break a circuit at zero. The other receptacle is independent of the switch and will always break the circuit at zero. Large numerals on a 6.5" face are easy to read. The outer ring indicates elapsed time, while the inner circle may be used as a stop clock. Variable volume control enables you to adjust the buzzer alarm so it can be heard above ambient noise levels or make a quieter sound.

Rubber base pads, wall mounting keyholes and a recessed hand grip on the sturdy polycarbonate case give you multiple placement options. There's also a permanent plastic boot over the power and outlet control switches to prevent contamination or corrosion.
