PMI (POSITIVE MATERIAL IDENTIFICATION)
Positive Material Identification (PMI) is a fast and non-destructive testing (NDT) method for verifying the chemical composition of metals and alloys.
Spectral analysis is a materials-testing procedure used to determine the chemical composition of metals. The method is also referred to as optical emission spectrometry (OES) and plays an important role in the metal-processing industry.
MECHANICAL TESTING EQUIPMENT
Ultrasonic testing (UT) comprises a range of non-destructive testing (NDT) techniques that send ultrasonic waves through an object or material. These high frequency sound waves are transmitted into materials to characterise the material or for flaw detecting.
A radiation detector or particle detector is a device that measures this ionization of many types of radiation, like- beta radiation, gamma radiations, and alpha radiation with the matter.
VERNIER CALIPERS, MICROMETERS
Calipers are used for measuring diameters, thicknesses, and lengths of small items. To measure an object, open the dial caliper to fit around its sides, and then close down the caliper until it touches both sides
