CV Instruments Durometer Digital DS is typically used to measure the material hardness of polymers, elastomers, and rubbers. Works on similar principle like metal hardness tester, Hardness measure with durometer herein is defined as a material's resistance or endurance to permanent indentation with calibrated means of force (in many case also called puncture). Equipped with Swiss made electronic sensor, CV Instruments Durometer Digital DS Series can be used in hand held mode or mounted onto a sturdy bench stand for improved accuracy and repeatability on your factory floor. CV Instruments Durometer Digital DS is manufactured in accordance with ASTM D2240 and ISO 868 which also supplied complete with UKAS calibration certificate.
In the application of CV Instruments Durometer Digital DS Series, there are several scales of durometer which need to be considered for measuring materials with different properties. The two most common scales, using slightly different measurement systems, are the ASTM D2240 type A and type D scales. The A scale is for softer plastics, while the D scale is for harder ones. However, the ASTM D2240-00 testing standard calls for a total of 12 scales, depending on the intended use; types A, B, C, D, DO, E, M, O, OO, OOO, OOO-S, and R. Each scale results in a value between 0 and 100, with higher values indicating a harder material.
CV Instruments Durometer Digital DS Series work like a common hardness tests as the measures of the depth on an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material along with its viscoelastic properties, the shape of the presser point, and the duration of the test. ASTM D2240 on CV Instruments Durometer Digital DS Series allows for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then read. The material under test should be a minimum of 6.4 mm (0.25 inches) thick.
The CV Instruments Durometer Digital DS is equipped with 35° blunt taper durometer point which is particularly useful in quality testing of higher precision the manufacturing of rubbery belt, rubber hose, insulation damper, kevlar vest and many more. CV Instruments Durometer Digital DS is fast easy-to-read instruments ideal for testing rubber, plastic, FRP, leather, wool fiber, soft gels and sponge rubber, felt, cotton fabric, chemical tubes container and all other soft materials with fibers. If you prefer value line with dial gauge, you can also opt for CV Instruments Durometer Analog SH.
