Electro-chemical Elapsed Time Indicators

These analog ETIs are constructed with unique ampere-hour meters-basically. a mercury coulemeter fabricated from precision-bore, glass capillary tubing. Two columns of mercury, separated by a small electrolyte gap, fill the tubing. The gap contains a glass-tube barrier that maximizes the unit's resistance to shock, therefore preventing loss of gap.
