^IMMB-It is a modern, electric stopwatch and second A totalizer combined, ideal for hundreds of laboratory and industrial timing jobs demanding split-second accuracy. Run by a synchronous motor, free from delicate mechanism or fine springs, Time-It betters the conventional stopwatch on many counts. It's as accurate as the cycle constancy of your A. C. current. Large, easy-to-read counter, directly indicates seconds and 1 10 seconds, totalizes to 10,000 seconds (2 hours, 46 minutes) before starting back at zero; can be reset to zero from any reading. Finger tip stop-start control; mechanism fully enclosed in sturdy aluminum housing to take gruff handling; built-in stop brake promotes accuracy; convenient size for panel mounting or portable utility use.
