Stiffness & Hardness Tester Suppliers in Hobart

A hardness tester is a device used to measure the hardness of a material. There are several types of hardness testers available in Australia, including:

• Rockwell hardness tester: This tester uses a diamond cone or steel ball to make an indentation on the surface of the material. The depth of the indentation is then measured to determine the material's hardness.
• Vickers hardness tester: This tester uses a diamond pyramid to make an indentation on the surface of the material. The size of the indentation is then measured to determine the material's hardness.
• Brinell hardness tester: This tester uses a steel ball to make an indentation on the surface of the material. The diameter of the indentation is then measured to determine the material's hardness.
• Shore hardness tester: This tester measures the hardness of materials such as rubber, plastics, and other elastomers. It uses a spring-loaded indenter to penetrate the material and measure the resistance to penetration.
• Knoop hardness tester: This tester uses a diamond pyramid to make a small indentation on the surface of the material. The size of the indentation is then measured to determine the material's hardness.

Overall, the choice of hardness tester depends on the type of material being tested and the required accuracy of the results.

Selection of the right hardness tester for a specific application depends on various factors such as the type of material being tested, the required accuracy, the testing environment, and the testing frequency. Some common types of hardness testers include:

• Rockwell hardness tester: Suitable for testing hard materials such as metals and alloys.
• Brinell hardness tester: Ideal for testing soft materials such as plastics, rubber, and non-ferrous metals.
• Vickers hardness tester: Suitable for testing thin samples or small parts, and for measuring microhardness.
• Portable hardness tester: Ideal for on-site testing and for testing of large and heavy parts.

When choosing a hardness tester, it is important to consider the specific requirements of the application, the budget, and the availability of trained personnel to operate and maintain the equipment. It is also advisable to consult with experts in the field and to conduct a thorough evaluation of the equipment before making a final decision.

Prices in Australia vary depending on the type and brand of the instrument. Basic models can be found for around $500, while more advanced models can cost upwards of $10,000. It is recommended to research and compare prices from different suppliers before making a purchase.

Calibration and maintenance are important aspects of ensuring the accuracy and reliability of hardness testers. The following are some of the calibration and maintenance requirements for hardness testers:

• Calibration:
• Calibration should be performed regularly to ensure accurate measurement results.
• Calibration should be performed by trained technicians using calibration standards that are traceable to national or international standards.
• Calibration should be performed at the recommended intervals specified by the manufacturer.
• Calibration should be performed after any repairs or modifications to the hardness tester.
• Maintenance:
• The hardness tester should be kept clean and free from dust and debris.
• Regular inspections should be performed to identify and address any signs of wear or damage.
• The hardness tester should be stored in a dry and stable environment, away from direct sunlight and extreme temperatures.
• The indenter and anvil should be cleaned and inspected regularly for wear and damage.
• The test force should be checked periodically to ensure it is within the specified range.
• The hardness tester should be lubricated according to the manufacturer's recommendations.

By following these calibration and maintenance requirements, hardness testers can provide accurate and reliable measurements for many years.

Yes, it is possible to rent or lease a hardness tester in Australia. There are several companies that offer rental and leasing options for hardness testers, including NDT Equipment Sales, TechRentals, and Test Equipment Hire Australia. The rental or leasing fees will vary depending on the type of hardness tester and the duration of the rental or lease agreement. It is recommended to compare prices and features from different companies before making a decision.

It is recommended to contact several suppliers and compare their delivery times and prices to make an informed decision.

Warranty periods in Australia vary depending on the manufacturer and the specific model of the hardness tester. It is recommended to check with the manufacturer or supplier for the specific warranty information. Generally, warranties range from one to three years.

Hardness testers are generally considered to be highly accurate tools for measuring the hardness of materials. The accuracy of a hardness tester depends on the type of tester used, the calibration of the tester, and the skill of the operator. Some common types of hardness testers include Brinell, Rockwell, Vickers, and Knoop testers. Each type of tester has its own unique method of measuring hardness and comes with its own set of benefits and limitations.

• In general, most modern hardness testers are highly accurate, with many models capable of measuring hardness to within a few tenths of a percentage point.

To ensure the highest level of accuracy, it is important to calibrate a hardness tester regularly and to follow proper testing procedures. Additionally, it is recommended that users of hardness testers undergo training and certification to ensure they are properly using the tool and interpreting the results.

There are several hardness scales used in Australia, including:

• Rockwell hardness scale: This measures the hardness of metallic materials and is commonly used in manufacturing and engineering industries.
• Brinell hardness scale: This measures the hardness of metallic materials by indenting a sphere of a specified size into the surface of the material.
• Vickers hardness scale: This measures the hardness of metallic materials by indenting a diamond pyramid into the surface of the material.
• Mohs hardness scale: This measures the hardness of minerals and is commonly used in geology and mineralogy.
• Shore hardness scale: This measures the hardness of rubber and plastic materials.
• Knoop hardness scale: This measures the hardness of brittle materials, such as ceramics and glass.

There are various types of hardness testers available that are designed to measure the hardness of different materials using these scales.

Manufacturers usually offer training and technical support for their products. It is recommended to contact the manufacturer or supplier from where you purchased the hardness tester to inquire about the availability of training and technical support. They can provide you with information on how to properly use and maintain your hardness tester, troubleshoot any issues, and answer any questions you may have. Some manufacturers also offer online resources, such as user manuals and instructional videos, to assist with the operation and maintenance of their hardness testers.
