1. A measurement arrangement for use with a multiple zone removable sensor disposed at least partially within the measurement arrangement, said measurement arrangement including means for applying an electrical signal to said sensor to produce a measurement signal and a cutting device for cutting a zone from said multiple zone removable sensor after the zone has been brought into contact with a sample to effect a measurement, said cutting comprising:

  • a lever fixed to a first axle pivotable about a first axis;

    a second axle having a second axis, said second axle being movable about said first axle;

    a crank having a first end coupled to said second axle and freely pivotable about said second axis, said crank having a second end to which a blade is mechanically coupled;

    means for mechanically coupling said first axle to said second axle whereby pivoting of said lever causes movement of said crank; and

    ,a guide for guiding said second end of said crank along a path so that said second end of said crank moves toward and away from a multiple zone removable sensor as said lever is pivoted in a first and a second direction, respectively, whereby said blade cuts a multiple zone removable sensor disposed in said path and said blade is then retracted.
