Click images to enlarge.
The PosiTector® SHD is an advanced Digital Durometer for hardness measurement of rubber, plastic, epoxy and more. The PosiTector® SHD features a color LCD display with user-adjustable measurement time with onscreen countdown for testing according to national and international standards. The standard model has 1000 reading memory and USB output, the advanced model adds memory for 250,000 readings in batches, live graphing, WiFi and Bluetooth output.

The PosiTector® SHD Shore Hardness Durometer can be used as a handheld instrument or placed in a test stand to reduce operator influence.

The display can be used with our full line of Positector probes to measuring, coating thickness, wall thickness, surface profile, dew point and more.

FAQ's (Frequently Asked Questions)

Do your instruments require any formal training for use? Do you offer ‘demo’ models?
No. Our instruments are designed for simple operation, feature easy-to-use menus, both full and quick instruction manuals, and helpful videos. In lieu of demonstration models, we provide unlimited technical support via telephone and/or email, and a limited 30-day money back guarantee.

Is the PosiTector® SHD calibrated at the factory?
The PosiTector SHD arrives fully calibrated and ready to measure. A Long-Form Certificate of Calibration traceable to NIST or PTB is included, which documents actual readings taken by your instrument at our calibration laboratory on standards traceable to a national metrology institute. Beware of ‘Certificates’ or ‘Certificates of Conformance’ offered by competitors. These typically do not include actual instrument readings, and are often insufficient to meet common quality requirements.
The included Test Block allows the gage operator to quickly verify correct operation and accuracy of the SHD.

What is the difference between Shore A and Shore D durometers?
PosiTector® SHD Shore Hardness Durometers measures the indentation hardness of non-metallic materials such as polymers, elastomers and rubbers. In the corrosion industry, durometers are commonly used to ensure proper curing of thick coatings and pipeline repair wraps.
The two PosiTector® SHD models look and operate identically, and vary only in the spring pressure and shape of the intender tip. This allows the two models to accurately measure different hardness ranges:
-Shore A (SHDA)- for soft to hard materials such as soft rubber, elastomers, neoprene, silicone, etc.
-Shore D (SHDD) - for medium to extra hard materials such as hard rubber, epoxies, hard plastics, PVC, acrylic, etc.

Can the PosiTector® SHD measure the hardness of metals?
No. Shore Hardness Durometers are designed to measure the indentation hardness of non-metallic materials such as polymers, elastomers and rubbers. Nearly all metals are outside the Shore Hardness scale. The manufacturer does not currently manufacture instruments for testing the hardness of metals.

Does the PosiTector® SHD include a fixture stand?
No. A PosiTector® SHD Test Stand is available as an accessory item for both SHDA and SHDD instruments.

What is the minimum thickness of material necessary to measure with the PosiTector® SHD?
‍According to ASTM D2240-15 “Standard Test Method for rubber Property – Durometer Hardness”, the test specimen must be at least 6.0 mm (0.24 inches) thick unless it is known that equivalent test results can be obtained with a thinner specimen. Since in-field use of a Shore durometer can concern testing the hardness of an applied coating with a measured thickness less than 6.0 mm, it is incumbent upon the operator to be aware of both the required coating thickness and its expected hardness for a particular application. Both the coating thickness and expected hardness will be specified by the coating manufacturer. Given the wide variety of coating types extant, the manufacturer has no ability to indicate a minimum coating thickness suitable for testing with our PosiTector® SHD.

Does the PosiTector® SHD measure Rockwell/Brinell/Barcol hardness?
No. The PosiTector® SHD Shore Hardness Durometer measures the Shore indentation hardness of non-metallic materials such as polymers, elastomers and rubbers. The manufacturer does not currently make other types of hardness testing instruments.

How often should the PosiTector® probe be recalibrated?
PosiTector® probes include a Certificate of Calibration with no expiry or end date. They have no shelf life, therefore the length of time in the field is not a good indicator for recalibration intervals. Many organizations with quality programs and recertification programs require annual recalibrations, and this is a good starting point for most users. The manufacturer recommends that customers establish calibration intervals based upon their own experience and work environment. Based on our product knowledge, data and customer feedback, a one year calibration interval from the date the instrument was placed in service is a good starting point.
