CIRCULAR DUROMETERS
We manufactures a wide variety of durometers for polymers, composites and like materials to measure hardness of natural and synthetic rubber products, acrylics, acetates, polymers, thermoplastics, PVC, hardboards, wood, fruits and many other non standard materials.
Round type analog Durometers have a dial graduated from 0 to 100 spread across 360 degrees thereby making it easily readable and accurate in measured values.
The circular Durometers are provided with a maximum indicating hand for determination of creep properties of materials under test. The circular Durometer SHORE A is supplied with a unique 3-in-1 test gauge to check the accuracy of Durometers at 25,50 and 75 hardness nos.
DUROMETER STANDS
These are standard devices suitable for holding the Durometers so as to allow for a series of tests quickly.
The tester is fitted on to the pins in the stand and the specimen kept on the platform is lifted to the tester by pressing the knob.
Separate stands are used for Shore-A and Shore-D testers as each stand has a separate built in loading device to give a constant contact pressure confirming to international standards.

ANALOG CONSTANT CONTACT PRESSURE - DUROMETERS
It is designed to minimize the possibilities of variations in readings resulting from various contact pressures of manual operation. These are offered both in analog as well as in digital models.
The analog model SHR - A - SUPER - Y2K® / SHR - D - SUPER - Y2K® has a specially designed CONSTANT-CONTACT-PRESSURE LOAD-CELL internationally patented which earned us not only the NATIONAL AWARDS FOR INVENTION but was also awarded the GOLD MEDAL at the IENA (INVENTORS' FAIR) at NUREMBERG-GERMANY in October 1999.
Constant-force analog tester is available in Millennium series such as:
- MODEL : SHR - A - SUPER - Y2K®
- MODEL : SHR - D - SUPER - Y2K®
DIGITAL CONSTANT CONTACT PRESSURE - DUROMETERS
In Digital version, the constant force is achieved by a series of special springs.
The salient features are:
- "SET","ZERO" and "HOLD" facility
- Large clear digital display
- Battery operated - 1.5 v, SR 44
- Digimatic output from 0 to 100 units
- Manufactured in accordance with International Standards
- MODEL : SHR - A - Di - Y2K®
- MODEL : SHR - D - Di - Y2K®
