ＰＨ Value Measurement
TheｐＨ (power of Hydrogen) value is a measure of the acidity or alkalinity of a material, typically of aqueous solutions. It is measured on a scale of 0 to 14, where 7 is neutral, 0 – 6 is acidic and 8 -14 is alkaline. Measuring theｐＨ of a material is a very important p......

Specific gravity determination
Specific Gravity Testing
Specific gravity testing is a method of measuring the density of liquid, or the relationship between mass and volume of the liquid. The term specific gravity is derived from the density of the substance relative to the density of water. Specific gravity testing is frequen......
surface treatment
Surface treatment is a very important process in the production of various components. While there are many techniques employed to achieve the desired surface properties, the goal is to increase the durability and wear resistance of the component. The primary types of surface treatments are therma......
