Specific Gravity Balance - Digital
Specific Gravity Balance - Digital

Specific Gravity of any elastomer is or considerable importance for its identification. Besides it can also be used for providing a rough assessment of its physical properties. It can also be used for finding if the sample and the products are prepared from the same compound or not.

Displays direct specific gravity digitally, No calculations required. Based on the Archimedes principle.

Designed for use in laboratory applications, it is easy to use two-button operation, a high-contrast LCD display.

Designed for use in Laboratory applications, highly accurate features easy to use two button operation. The option of either RS 232 or USB connectivity available.

    Digital Tensile Strength Tester  
    Digital Tensile Strength Tester
    Digital Tensile Strength Tester for plastic, rubber & metal is based on the Constant Rate of Traverse (CRT) principle. The sample is held between two jaws, the upper one is a stationary jaw while the other end is made to move at a known fixed speed with the help of Motor, Gear Box and Lead Screw arrangement (75mm or 300mm per minute). The load exerted on the Stationary jaw is sensed by a sensor connected with load cell which directly indicates the load in Digital form in kgs. The Elongation is digitally displayed.

    Technical Specifications:
    Capacity of the Tester 0 - 250Kg/ 0 - 25N
    Sensitivity 100 Gms.
    Speed of Machine 75 mm per. Minute, 300 mm per. Minute
    Minimum jaw separation 25 mm
    Maximum jaw separation 750 mm
    Motor ¼ HP Single Phase 220 / 110 V AC Supply.
    Power Consumption 1KW

      Digital Tensile Testing Machine

    The Presto Digital Tensile Strength Tester is electrically operated and is used to check the physical Impurities. It is basically vertical type, limit switches are incorporated for both the direction so to limit the traveling range. The accuracy of the machine is with in permissible limits as par IS:1828.

    The test specimen is held between two grips the upper one of which is connected to the load indicating arrangement while the lower moves down at constant speed with the help of a motor operated screw. The elongation is measured as the displacement of the lower grip. The equipment is designed to test as per Indian and other international specifications.

    Models available from 500 kg to 10,000 kgf.
