Types of Webster Hardness Tester

01/

Brinell Testers
The brinell hardness tester is known for its accuracy and reliability, and is ideal for measuring the hardness of soft and non-ferrous metals. The brinell test involves pressing a hardened steel ball into the surface of the material and measuring the size of the resulting indentation.

02/

Knoop Testers
The knoop hardness testers identify microhardness when measuring thin coatings and small parts. The knoop test involves pressing a diamond tip into the surface of the material, creating a small indentation that is measured using a microscope.

Rockwell Testers
The rockwell hardness tester is a popular tester used for measuring the hardness of metals, plastics, and other materials. The rockwell test involves pressing a diamond cone or a steel ball into the surface of the material, and the depth of the indentation is measured using a gauge. The rockwell hardness tester is widely used due to its ease of use, accuracy, and versatility.

05/

Shore Testers
The shore hardness tester is a portable device used for measuring the hardness of soft materials, such as rubber, plastics, and foam. The shore test involves pressing a small indentor into the surface of the material, and the hardness is determined by measuring the depth of the indentation.

06/

Vickers Testers
The vickers hardness tester is a microhardness tester used for measuring the hardness of small and thin samples. The vickers test involves pressing a diamond pyramid tip into the surface of the material, creating a small indentation that is measured using a microscope.

How To Operate A Wechsler Hardness Tester

Turn on the Wechsler hardness tester and allow it to warm up for a few minutes.
Select the appropriate indenter and load it onto the tester. The indenter is the tool that will be used to make an indentation on the material being tested.
Place the material to be tested on the anvil of the tester. The anvil is the flat surface that supports the material during the test.
Adjust the height of the tester so that the indenter is in contact with the surface of the material.
Apply the load to the material by turning the hand crank or pressing the button on the tester. The load should be applied gradually and evenly.
Hold the load for the specified amount of time, usually between 10 and 30 seconds.
Release the load and remove the indenter from the material.
Measure the size of the indentation using a microscope or other measuring device. The size of the indentation is used to calculate the hardness of the material.
Record the hardness value and repeat the test on other areas of the material if necessary.
Clean the indenter and anvil after each use to prevent contamination and ensure accurate results.

How to Maintain Webster Hardness Tester

To Avoid Being Stained
When using this portable hardness tester, we should often wipe it with soft cloth in case that the dirt goes into it from the gap of dial or from the places around the pressing needle. If not, the dirt which has been in the instrument will affect the measuring accuracy badly or lead to its breakdown.

To Avoid Being Rusted
Although all the parts of the instrument have been given anti — rust treatment, it may still cause some parts to be rusted if there is poor maintenance. Especially, to focus on not being watered, because many of them will rust when they meet water. Gauge outfit could be rusted buildup and then results in rejection of the instrument if the inside of gauge outfit has water.

To Avoid Dropping
This portable hardness tester consists of many precise parts. If it drops, it will turn some parts into the permanent damages.

Do Not Disassembly
The promise of the measuring accuracy from this instrument relies on some precise components that are cooperating well. Therefore, except the detachable ones that are in correction, they can be taken apart any more. Otherwise, it will bring some troubles to you and the instrument will be disqualified of warranty.

To Make Corrections
When using the detecting instrument, we should pay attention to its accuracy frequently , and to check whether the full scale（20hw） of instrument and calibration point is right or not. Once the inaccuracy found, we should correct it in time. Besides, to decrease the times of striking in case of the abrasion of pressing needles.

The Illustrations Of Consumptive Material
Pressing needles belong to consumptive material, which is no within the warranty. Its service life depends on whether the using method is right and the maintenance and repair is timely as well as appropriately or not.

① The service life of pressing needles has direct relations with using frequency of customer’s instrument and harness range of measuring workpiece. The more frequently the customer use and higher harness of measuring workpiece, the greater abrasion the pressing needles will be, causing its service life to be shorter.

② Keeping the sample from twisting when you are measuring, or it will cause the error and even damage the pressing needles. To strictly prohibit using harness clamp to pull the material out from material basket directly; otherwise, it will ruin the pressing needles immediately.

③ When measuring the material, it is no necessary to use specially great power to clench the hardness clamp. Do not rush to increase the strength to make sure that will not damage the instrument and its accessories.

Transportation
During the long — distance transport, please to try to use package reserved for webster hardness tester, which helps to minimize the damages and incorrectness of instrument made by external force.

How Does Webster Hardness Testing Work

Webster hardness testing works by pressing a standardized, hard instrument into the material that is being tested. The instrument, called an indenter, is pressed into the sample for a standardized length of time (a number of seconds), and with a specific load (force) behind it. When the indenter is pressed into the material, it deforms the surface of the material by a measurable amount. This deformation is then measured, and the measurement is used to assign a hardness value to the material according to the test’s specific scale.

What Is the Hardness Test Standard of Wechsler Hardness Tester

Astm e10
This standard covers brinell hardness testing in metallic samples.

Iso 6507
This standard contains the details for the vickers hardness test in metallic materials.

Iso 6508
This standard is very similar to astm e18, as it deals with the rockwell hardness tests, both superficial and regular, for metallic samples.

Iso 4545
This standard covers knoop hardness testing for metals.

What You Should Pay Attention to When Choosing a Wechsler Hardness Meter

Test Load
The hardness of the material determines this. For steel or alloys, test loads are up to 3,000 kgf. Soft metals, on the other hand, only require a test load of 500 kgf. The higher the load used, the higher the accuracy of the test. The indentation left on the object during testing should not exceed 10% of its thickness.

Hardness Range
This is the factor that determines the material of the indenter. If you are working with a hardness higher than 650 HB/30, you will need a diamond indenter. If the object you are testing has a hardness value lower than this, you should use a steel or hard metal indenter.

Accuracy Level
This depends on the surface you want to measure. Factors such as surface cleanliness, texture, system, etc. all come into play.

Equipment Adaptability
Choosing an appropriate hardness tester should consider the shape and size of the material being tested.
