Details of Testing Equipments::

Optical emission spectrometer (OES): Spectro Analytical, Germany make for ferrous alloy (Low alloy steel, cast iron, stainless steel, tool steel) aluminum & its alloy and copper & its alloys. It is having small sample attachment ( 6 mm dia min. sample can be tested) A adequate certified reference standard sample is available for calibration.
Universal Testing Machine (UTM): It is FIE make having 40 tonne capacity and it is computerized one and a online graph get plotted on screen during testing. An extensometer is also available to find (0.2/0.5/1.0%) proof stress.
Micro Hardness Tester: A Mitutoyo, Japan make and it is having 10 gm to 1.0 kg load. It is used to check Vickers hardness upto 1 kg load, effective case depth by hardness traverse method.
Rockwell cum Brinell Hardness Tester: Saroj Engg make to be used for mainly for Rockwell scale HRC/HRB/HRA etc and Brinell hardness testing. A separate fixture has been developed to check diameter of impression of Brinell Hardness Testing.
Rockwell Superficial hardness Tester: Saroj Engg make to be used for superficial Rockwell scale such as HR-15N, HR-30N, HR-15T, HT-30T etc.
Magnetic Crack Detector: Magnafield make used to check surface and sub surface cracks.
Inverted Metallurgical Microscope: Zeiss, Germany make and having 100, 500 and 1000X magnification with image capturing and analysis option with using Metallography India Make image analyser software.
Stereoscope: It is customized technology make used to capture the image and can check all the possible dimensions. Magnification available is 13 and 71X. It is used for visual Inspection cum measurement.
Impact Tester: It is Fasane make having 320 Joules capacity. It is used to check impact strength in charpy as well as izod method.
Dynamic Portable Hardness Tester: It is Fasane make and used to check hardness of bigger parts which is not possible by conventional method.
Sample Preparation Machines: cutting, polishing, lapping, hot moulding, lathe machine, power hack-saw machine, muffle furnace, oven etc. Auto Polishing and Auto hot mounting press is also available.
Brinell hardness Tester-3000D: Saroj Engg. make to be used for Brinell Hardness Test using different loads such as 250, 750, 3000 Kgs Load etc and different indenter dia such as 2.5, 5.0, 10.00 mm etc.
Zwick make Micro Hardness Tester: It is Zwick-Roell make Micro Hardness Tester which is used to check hardness in Vickers upto 1 Kg load and also case depth by hardness traverse method.

Shimadzu, Japan make Fourier Transform Infra Red (FTIR) Spectrophotometer "IRAffinity-1SWL" : It is used for mainly for identification of Plastic/Rubber/Chemical/ Liquid etc. It covers the full Infra Red Range from 7800 cm-1 to 350 cm-1. A spectrum using infra red rays is generated from the unknown sample and the spectrum is compared with the spectrum of master sample from the library in which most of the plastic/rubber sample spectrum is included.The instrument can identify Nylon 6 or Nylon 6_6 material, Homo polymer or Co-polymer etc. It also indicates the contamination in the sample.
