Portable Hardness Tester

TH130 is an advanced integrated hardness tester distinguished by its very compact size, high accuracy, wide measuring range and simplicity of operation. It is suitable for testing the hardness of all metals, and widely applied in many areas of industry.

TH 130 hardness tester combines the universal impact device D and a data processor in a single unit. It automatically computes all Vickers, Brinell, Rockwell, or Shore hardness values. The impact direction can be set so that accurate values can be achieved at any angle, even up-side down. Statistical mean value is automatically provided.

The measuring method of TH 130 is defined as " the quotient of the impact body's rebound velocity over its impact velocity" When the tester is connected to its associated printer it can perform real time printing. It can also be equipped with optional accessories, such as support rings, to meet the requirements of specialized applications.

Typical Applications :

  • In situ testing of large and/ or heavy components, items installed as parts of a machine.

Carbon & Sulphur Determination Apparatus

Item Code: EIE-175
Semi Automatic – Single Burette Determination of Carbon and sulphur contents in Iron and steel has becomean absolute necessity forall Iron processing plants, foundries etc. There is substantial saving of time and effort, as in a short time, both carbon and sulphur can be determined in one action. This dual determination is excellently suitable for routine analysis.

  • Simplified operation
  • Substantial saving of time.
  • Accuracy and ease of operation Advantage of cheapness through saving of power and chemicals due to dual determination Steel or Iron chips of samples under test are heated in a stream of oxygen gas to about 1200 deg.-1350 deg. C converting carbon and Sulphur contents to carbon dioxide and sulphur dioxide gases respectively. These gases are passed through a solution of hydrogen peroxide. The sulphur dioxide gas dissolves in hydrogen peroxide forming sulphuric acid which is titrated against caustic soda solution of known strength to determine the percentage of sulphur in the sample under test. The gaseous mixture from which sulphur dioxide has been removed (absorbed) is now taken in to a calibrated burette. Then the gases are taken into an absorption vessel containing potassium hydroxide solution to absorb carbon dioxide gas. The reduction in volume of the total gas equals the volume of carbon dioxide gas : knowledge of which then gives the amount of carbon. The scale reading directly gives the percentage of carbon in 1 gm. sample.
