Mass Calibration

E1 class weights
Traceable weighing results require traceable mass standards. Our E1 class weights satisfy OIML R111 (International organization on legal Metrology) recommendations. The use of appropriate mass weight and their correct treatment at all times is essential to mass metrology. Our E1 class weights have got treaceability to NPL, New Delhi. Their range is from 1 mg to 1kg.

Range: 1mg to 1kg (Stainless steel weights)
Accuracy: E1 class
Traceability: NPL, New Delhi.

F1 class weights
Range: 1mg to 40kg (Stainless steel weights)

Pressure Calibration

Dead Weight Tester(DWT)
Dead weight testers are the basic primary standard used for accurate measurement of pressure. No other equipment can match the stability. It is ideal for calibrating pressure gauges, transducers, digital calibrators etc. and can also be used to directly measure the pressure in system and processes when precision reading is important. The calibration Techniques is cross-floating method.

Material Testing

Universal Testing Machine
Universal Testing machine is electromechanical machine with digital display of load & displacement and have system for changing speed. The machine is design for testing various materials like plastics, cable, leather and metals. Tension and compression can be performed on this machine with suitable grip and fixtures.

The main features are

	Selection of different speed
	Facility to mount different load cells
	Facility to mount different grips and fixtures for different test and materials.
	Digital display of load and displacement
	Storage of important parameters such as peak load, breaking load and max. Displacement.
	Facility to return of cross head to home position for next tests.

A brief description f the machine is Make/Model: Unitek 9400
Capacity: 10 tonns with 12mm dia.

Hardness Testing Machine
Hardness is defined as “ Resistance of metals to plastic deformation usually by indentation”. It is a property of a metal, which gives it the ability to resist being permanently deformed (bent, broken or have it shape changed) when load is applied. The greater the hardness of metals the greater the resistance it has to get deformed.

A brief description of the machine is
Type: Vickers cum Brinell hardness testing machine
Make: Techno Instruments
Model: BV 250
Range: 5kg to 250kgf

The main features of the machine is

	Testing range is very wide, from soft metals such as lead up to the hardest, like hardened steel.
	Thin sheet metals is perfectly tested because the load applied is very small.
	Same hardness number is obtained on the same specimen, regardless of load applied.

Fatigue Testing Machine
Fatigue Tests are made with the object of determining the relationship between the stress range and the numbers of times it can be applied before causing failure. Testing machine are used for applying cyclically varying stress. This is a rotating beam type Machine in which load is applied in reverse bending fashion. The standard 8mm dia specimen is held in the specimen holder.

A brief description of the machine is

Type: Fatigue Testing machine
Make: Techno Instruments
Model: FTG-8 (D)
Max. Bending moment: 200kgcm
Testing dia: 8mm

The features of the machine is

	Simple lever system of changing load.
	The bending moment is applied with a lever system and can easily be changed by moving a weight over the lever.
	A digital counter records the total number of revolution at which the specimen fails
