Durometers
Hardness is one of the most significant physical properties of elastomeric compounds. The hardness reflects all, or in part, such other qualities as resilience, durability, uniformity, tensile strength, and abrasion resistance.
Features
- Meets or exceeds current ASTM D2240 specifications.
- Individual test report included with each instrument.
- Rugged construction, with all working parts totally enclosed.
Model 306L
The Model 306-L and 408A Scale Durometers are designed to measure the penetration hardness of rubber, elastomers, and other rubber-like substances such as neoprene, silicone, and vinyl and butyl. It can also be used for soft plastics, felt, leather and similar materials. It is built to meet or exceed American Society for Testing and Materials, Specification D2240-81.
Wherever there is a need for checking and standardizing plastic parts, the models 307-L and 409D can be used. These cover the broad spectrum of industrial, commercial and military areas. The models 307-L and 409D are designed for plastics— polystyrenes, vinyls, Formica, Plexiglas— hard rubbers and phenolic molded materials. These durometers are used for applications which vary from checking the hardness of contact lens blanks to bowling balls.
The heat-treated, high carbon steel mainspring is precision centerless ground. Each spring is calibrated to the specified tolerances. A special cam arrangement permits a scale deflection of 100 points when the indenter is displaced exactly 0.100".
The non-glare, brushed aluminum dial scale is extended over 240 circular degrees to provide a reading accuracy well within 1% of the calibration curve.
An 8-32 threaded mounting knob at the top of the durometer permits permanent test stand emplacement. Each durometer is provided with a test block of steel which is far more independent of temperature changes than in a plastic block.
Model 408
With removable mounting knob which allows comfortable handheld use or test stand emplacement.
