ASKER X-AL Durometer / Hardness Tester

Model X-AL for Normal Rubber With Long Presser Foot

• High performance and accuracy
• Calibration cert traceable to NIST included
• Optional ISO-17025 calibration available

The Asker Model X-AL Durometer is a precision instrument for measuring the hardness of various types of rubbers and plastics. Durable metal cases are rugged enough for a production environment. X handheld durometers are easy to use. The easy operation allows for rapid testing with repeatable results. The Asker High Performance X-AL series has an accuracy of ±.75 points.

Operation

As the X-AL durometer is pressed against the sample, the material resistance force and indentor spring load balance. The depth of the indentor is measured, which provides a measure of the material’s hardness. Values are based upon a 100 point scale (accuracy ±.75 point). However, as time elapses the indicator will “creep” back so that a reading taken a few seconds after the indentor makes contact with the sample will be less than the peak reading. Asker durometers offer a peak indicator as an option to more closely monitor the difference between peak and “creep”.

What’s Included with the Durometer?

X-AL durometers are sold as kits. All new durometer purchases include: durometer, hard plastic carrying case and 3-Point Calibration certificate traceable to NIST. An ISO-17025 accredited calibration is available for an additional charge.
