ElasTek™ ASTM D926 Digital Thickness Gauge
ASTM D926 Thickness Gauge
	The ASTM D926 Digital Thickness Gauge is specifically engineered for determining the plasticity recovery of test specimens where conformance to Procedure A or Procedure B of ASTM D926 Standard Test Method for Rubber Property—Plasticity and Recovery (Parallel Plate Method) is required.
	Although configured for D926 dimensional measurements, the gauges may also be used for “standard measurements” ... virtually eliminating the need for multiple or dedicated gauges.
	Each ElasTek™ ASTM D926 Digital Thickness Gauge is individually assembled and calibrated to assure that the inherent frictional resistance of the mechanism, as well as the force introduced by the mass of the movement assembly, is ultimately considered.
Additionally, each mass is matched to the selected stem and contact combinations to attain an optimal “pressure” profile.
Supplemental stem, mass, and contact sets are available to allow this digital gauge to be easily modified to measure virtually any size and hardness combinations of test specimens. Simply replace the exchangeable mass, contact, or stem to suite the application!
The granite base provides an accurate reference plane as well as a stable support, the mass being sufficient to prevent unintended movement. It is a hard, smooth contact surface, which is easily cleaned and impervious to most environmental effects.
ElasTek™ also provides volumetric and rotating cutting Specimen Cutting Dies for the preparation of ASTM D926 test specimens.
