Incremental reduction in width monitor The incremental reduction in width monitor is designed for r-value determination on metals to ASTM E 517 and ISO 10 113.The clip-on extensometer measures the change in widthon metallic specimen via a measurement line. It can be used either alone or in combination with the Macro, Multisens or Longstroke extensometer.Its low height enables it to be easily clamped on thespecimen between the sensor arm pairs, thus enabling extension and change in width to be recorded in one gauge length. Incremental clip-on extensometer forextension measurement Zwick offers two versions within the incremental clip-on extensometers for extension measurement. They differ in the measurement path length.They are suitable for precise modulus and yield pointdetermination to ISO 527-1 on stiff and slightly flexible plastics as well as for determination of strain at maximum stress, and for strain at break on stiff plastics. Apart from this, they are also suitable for determination of the compressive strength of plastics or for determination of the compressive E-Modulus for metals.The second version is especially suitable for tests up tobreak on metals owing to its long measurement paths, they cover up to 50 % strain.The initial gauge lengths for both systems are adjustable.

Its measurement path is very long both for extension and change in width measurement.
