The concept of hardness tester
A hardness tester, or TDS, is a device that measures the sum of liquid-soluble particles that represent salt ions in water. TDS stands for Total Dissolved Solid, which means the total concentration of all ions in water that can be measured by hardness meters. the unit TDS hardness test Mg / l Mg / l, which is also called PPM (part per thousand).
Hardness Tester High rigidity is a matter of concern. Overall hardness indicates the amount of magnesium and calcium ions dissolved in water. In fact, general hardness is a means of measuring metal ions such as calcium, magnesium and zinc, which are formed by the passage of rainwater through rocks.
1- Volumetric kits The
most common and accurate measurement method for measuring the concentration of ions in water are volumetric kits. In this method, a small cylinder and containers equipped with a dropper are used. The cylinder is filled to the mark line of the sample, and the necessary reagents are added to it. Drops of standard solution are added to the sample. When all the desired ions react with the standard solution, the sample will change color. This is known as the end point. The number of droplets consumed from the standard solution multiplied by a certain coefficient will determine the desired ion concentration.
2- Colorimetric kits
By this type of kit, the desired ion concentration is measured through colorimetric. A certain amount of chemical reagents are added to the sample, these reagents react with the desired ion and produce a specific color, the ion concentration is determined by comparing the intensity of the color created with the color sample of the test container.
Vicker hardness tester
in mechanical and metallurgical operations, its hardness and tester parameters play an important role, especially after kiln and hardening operations. Depending on the type of material, different standards, units, and methods for measuring hardness have been developed.
The most popular methods are Rockwell, Vickers and Brinell. In the case of digital hardness measuring equipment, we can refer to the portable examples with the probe, including the projectile and the launcher part. It is a special ball with a high degree of hardness embedded in a cylindrical device with a spring is thrown towards the surface of the metal and by measuring its return speed, its hardness can be measured.
The basis of most other devices is to create a point of effect on the metal surface, and by measuring the depth of this point, they measure the effect and the diameters of the role created on the metal surface, and then by matching those dimensions with the table prepared in advance. Has been, gain difficulty. This measurement technique is known as the Leeb rebound test.
The hardness industry, which is widely used today, plays an important role in mechanical operations and metallurgy. Because, as we know, these devices play a decisive role in the metal industry today.
Hardness Tester They are used to measure the hardness of metals, especially after hardening and furnace operations. The basis of their work is to create a point of effect and examine it on metal surfaces.
