Đồng hồ đo độ cứng cao su, nhựa PTC Asker C model 611
Asker C Durometers meet JIS K7312 and measures the indentation hardness of soft rubber, sponge, plastic foam, elastomers, and similar materials.
The Pencil Style Digital Durometers with a 1/2" diameter base (1.3cm) and overall length will allow the durometer to be used in confined or hard to reach areas with 0.1 reading resolution. A knurled surface gives a more secure grip when making hand held readings.
All Digital Durometers come complete with Electronic Max Hold feature, Test Block, Carrying Case and a NIST traceable certification.
PTC Metrology™ is accredited by A2LA for durometer calibration to ISO/IEC 17025 & ANSI/NCSL Z540-1. NIST traceable certification is available for all durometer types covered by current ASTM D2240, ASTM F1957, ISO 868, ISO 7619, and DIN 53505 Standards.
The Calibration Report will include both "as received" and "as left" data. Complete durometer calibration includes: indenter geometry and extension, indicator linearity, and force curve.
