Construction:

A machine frame with a drive system and specimen holder, abrasion drum, metal housing, electric motor for rotation of the drum and the specimen holder.

The machine can be supplied with a special brushes and vacuum cleaner in order to clean the dirt which gets accumulated on the drum. This greatly enhances the life of the machine and reduces cumbersome cleaning of the machine.

The machine confirms to DIN 53516, DIN ISO 4649

The digitest Gelomat is simial to the Digitest II rubber hardness testing machine in construction.

Machine Description:

It is a Micro computer controlled hardness tester with a very high measuring accuracy within the ranges of 0-2 N, 0-20 N.

Application:

Hardness- and firmness determination on soft elastic materials like Gelatine, Gelatine capsules, Modelling clay, Gel stability, automatic test run, flow curve, hysteresis curve etc.

Determination of the Gel stability of Agar-Agar and Gelatine and of the hardening of Gelatine capsules.

1. Schobb Type Pendulum Rebound Testing Machines:

The Digitest II Schobb type pendulum rebound tester is used for the determination of the resilience elasticity of elastomers, soft elastic foams and similar materials during shock or impact.

The Machine Confirms to DIN 53512, DIN 53573, ISO 4662, ASTM D 1054-91

Construction:

- The machine consists of a solid base to isolate vibrations and absorb impact. It consists of a specimen holder or anvil which is attached to an adjustable vernier to set the sample thickness.

- The hammer can be attached to the pendulum which is released from a position which is parallel to the ground.

- The high precision and quality bearings ensure very little bearing friction and helps in giving an accurate test result.

1. Temperature Retraction Testing Machines:

The TR-tester, is used for the determination of low temperature characteristics by the temperature retraction procedure according to ISO 2921.

The TR-tester is computerized and performs the test automatically after the cooling media has been cooled and the sample has been mounted. An automatic release of the samples, after the pre cooling period, is included.

The computer controls the temperature rise and measures the length change of the samples. The result is displayed as TR10, TR30, TR50 and TR70.

The result can also be presented as a table with length change versus temperature. The TR-values and the table values can be exported to other software as spread- sheets, for presentation as diagrams.

We also supply the machine with Liquid Nitrogen automatic cooling facility.

. Cabinet Oven: Model EB 04 and EB 10

Cabinet Ageing ovens for precision ageing of rubbers and plastics under controlled conditions. EB 04 and EB 10 are shelf ovens and conform to ISO 188, ISO 3383, IEC 811 and technical equivalent standards. They designed to give very low temperature variations in time and space, low air speed and controlled air exchange rate. This is achieved by using an inner chamber with a controlled air flow.

1. Stress Relaxation Testing Machines :

The Relaxation equipment for continous measurement in both compression and tension meets the requirements in ISO 3384 and ISO 6914. It can be supplied with the Draught Hood, to eliminate variations in force measurement due to temperature and air effects.

The relaxation rigs are used in combination with the cell oven EB 01 or EB 07 when testing at elevated temperatures. The cell oven EB 01 can accommodate four rigs at one temperature. In the cell oven EB 07, three rigs can be placed at three different temperatures.

Tests can be performed in tension and compression

We can also supply special fixture for performing the relaxation tests in liquid medium.

Optional user friendly relaxation software is also available.
