Cuvette belt faulty seal detector

摘要

A system for testing plastic cuvette belts for leak holes in the cuvettes comprises an array of conductive probes which are inserted into respective ones of a group of adjacent cuvettes. Alternate probes are biased to opposite high potentials sufficient to create arcing between the probes through any faulty seal in the cuvettes. A grounded electrode outside the cuvette enables holes to the outside to be detected also.
