Hardness testing on concave and convex surfaces

Different from the usual hardness testers that can only measure flat-surfaced samples, the NextGen's digitest II measures hardness on every surface by making use of an automatic surface detection technology. Also the indenter length is customizable, making it extendable to any point on the sample that is to be measured.

FAQs

The VLRH (Very Low Rubber Hardness) testing scale is unique to the DigiTest II system. It follows the DIN ISO 27588 principle and is typically used for thin sponge-like material including: sponge- and foam rubber, cellular rubber, silicone, etc. The primary differences between the scales is that the VLRH can do indentations on thinner specimens of 2mm. It is kind of like a Micro Test Head for Shore 00 and 000, except that it offers added versatility of being able to test on concave and convex surfaces.

The measuring ranges are comparable based on their corresponding standards ASTM D2240 (Shore 00/000) and DIN ISO 27588 (VLRH).

Normally, the calibration of shore hardness tester takes place annually, however this may vary based on your laboratory requirements. Some of our customers wait a few years before official calibration of their shore hardness testing heads because the unit still provides the exact same reading as the certified test blocks.

Provided you require calibration, you will have two options:

Option #1: Shipping Your Unit to NextGen
It is important to note that you do not need to ship the entire unit back to us for calibration. All that is required are the Shore/IRHD test heads.

Simply reach out to us at sales@nextgentest.com and please provide your serial number. We will offer the instructions to you.

Option #2: Loaner Program during Calibration
In order to avoid any production interruptions, we provide a loaner program option. This allows you to continue testing while your equipment is being calibrated. NextGen will send you 'loaner' calibrated test heads before you send yours out to us!

Here is what you do:

STEP 1:
Please provide details on the measuring head(s) you wish to have evaluated, calibrated and certified. We recommend doing this 45-60 days before the required calibration time.

Please provide the serial No. of the machine.

You may send request by e-mail to sales@nextgentest.com

STEP 2:
NextGen will outline the estimate for the loaner, the cost of a calibration service and the turnaround time. We will additionally offer all the shipping and logistics instructions for your convenience.

STEP 3:
Follow our instruction from step 2!

Should you have any further questions or require additional clarification, feel free to call us to speak with a qualified representative.

For Shore D testing, a complete system includes the electronic unit and interface, a pick-up bracket with loading device, the Shore D measuring device, the indenter, the additional loading weights and any required certificates required to maintain your records.

With some additional sample holders such as the Barofix or Centrofix, measuring O-rings has never been more simple!

The Digi-test is commonly found in the rubber and plastics processing industries, automotive, chemical, cosmetics, food, aerospace, research centers and institutes, pharmaceuticals, medical technologies and optical industries.

Besides Shore A, the Digi-test with separate accessories can test Shore scales A, A0, B, 0, C, D, D0, 00, 000, 000 S, E, micro Shore A, micro Shore D, C, D0, IRHD/DIDC M, N, H, L, and VLRH.

With the correct accessories, your Digi-test can absolutely double as an IRHD hardness tester.

The Digi-Test can accurately test Shore A as well as Micro Shore A. Shore A is designed for concave and convex molded parts of a material thickness of 4 to 6 millimeter. Micro Shore A is beneficial for those samples with a minimum thickness of 1mm.

The Digi-Test can test Shore D for measuring hard rubbers, semi rigid plastics and hard plastics. It also has the function of micro Shore D testing for samples with a minimum thickness of 1mm.

The Digi-test is commonly used for testing flexible mold rubbers that range in hardness from very soft and flexible through to hard materials with limited flexibility.

With Shore D, the recommended thickness of parts is 4 to 6 millimeter as it applies a very heavy load while measuring resistance to indentation.

The Digi-Test is a complete all in one solution, removing all human elements from your testing results, to provide the highest accuracy in quality assurance.

We happily provide calibration support, testing devices on loan during recalibration, testing services, maintenance contracts and in depth training.

There are a variety of scales for rubber testing with the Digi-test rubber shore hardness tester. Shore A, Shore D, Shore B, Shore C, Shore D0, Shore 00 and Shore 000. The specific scale will vary based on your specific material properties.

Shore hardness testing equipment is designed to measure a materials ability to resist indentation.

The Digi-test meets the following international industry standards: DIN ISO 7619, DIN ISO 48, DIN EN ISO 868, NF EN ISO 868, ASTM D 2240, BS 903 Part. A 26, NF T 46-003, ASTM D 1415, DIN ISO 27588

Besides exceptional support from pre-sale to after sale, we are happy to offer the official DKD/DAkks-Certificates for all exchangeable measuring devices on our Digi-test system.

The purpose of the IRHD hardness tester is to be able to conduct tests on O-rings. Simply let us know the type of materials and the diameter of your O-rings and we will be able to suggest the optimal IRHD head to meet and surpass your quality standard expectations.

The Digi Test is our bread and butter of automatic bench top durometer systems. This unit manufactured in accordance to the latest industry standards and quality manufacturing processes. The simple-to-use interface, exceptional accuracy, and unit's robust built designed to last for decades to come is the reason the Digi Test is currently the absolute global market leader in its field.

The current approximate lead time for the IRHD durometer system is 3 - 4 weeks. Depending on the production cycle and times of the year these lead time ranges may vary. Request quotation today to ask us for the current lead time.

The digital rubber hardness tester can accommodate rubbers, polymers, plastics and more. It can do virtually all materials other than metals.

The German DAkkS certificate offered with each digital shore hardness tester. NextGen is partnered with the only company in Germany which has double identities, manufacturer and DAkkS calibration lab. This allows for a one-stop solution for your manufacturing and certification needs.

The purpose of shore hardness testing equipment is to give a hardness result of a rubber or plastic specimen. Here is how do we compare to other manufacturers of shore hardness testers:

*Reproducible and reliable measuring results
*Robust and light-weight aluminum chassis (again good production quality)
*Does not break (except the wearable parts like the indenter)

Our automatic shore hardness testers are different from other manufacturing suppliers due to the production quality. What makes a Swatch different from a Rolex? After all, both give you very precise time indication.

Though we are not comparing ourselves to Rolex by price, we would like to make the bold statement that our equipment is the superior leader in quality production in the marketplace. All units are built with accuracy, user-friendliness, and maximum longevity in mind.

The IRHD and Shore Hardness Tester follow a variety of industry standards including:

DIN ISO 7619 / DIN EN ISO 868 / NF EN ISO 868 / ASTM D 2240 / JISK 6253 and more.

The display accuracy of the digital shore durometer system is to 1 digit after the decimal. Every machine comes standard with a DAkkS certificate which does a great job explaining all the mechanical tolerances. The superior accuracy of the unit gives our customers a peace of mind and the ability to achieve optimal measuring results every time.
