Abstract
Some of the advantages over the mechanical or the usual electronic interval-timers are listed, together with a schematic diagram and description of characteristic functions. "Probably the greatest value of the present timer lies in the fact that a number of identical units can be connected in series or in parallel to provide the timing for any expt. where the individual intervals do not exceed 111 sec.".Keywords
