We have Micro Hardness Tester from 1 Gram to 1/3 Kgs Load. In Manual, Digital , Semi auto, and Computerised version. 

Description:

• Micro Vickers Hardness Tester designed to cater heavy duty and research work with all the necessary automation for loading and measurements.
• Loading Mechanism Motorized loading and releasing.
• Indexing- Rotating turret for indenter and objective lens.
• Objective For scanning 10 x, Plan achromatic 0.25 NA.
• For measurement 40 x, Plan achromatic 0.4 NA.
• Diagonal Reading - Manual Filler micrometer eyepiece (10 X) with 0.5 Micron accuracy OR Digital measurement with the help of Digital Filler micrometer eyepiece (10 X) with 0.025 Micron accuracy.

Computerised Attachment: With this attachment one can convert manual hardness to computerized one. This has many advantages like higher accuracy as of bigger indentation, operator ease as one can get the Microhardness value by just clicking two diagonals of indentation image on the screens. Further one can get plot of effective case depth graph. All the readings with image and graphs can be stored, printed. This model MVH-II consists of

• 1/2" CCD Camera (High resolution monochrome) with interface adaptor
• Image grabber hardware.
• Dedicated image processing Software for Vickers Hardness number, effective case depth hardness graph. Hardness Conversion facility.

Rockwell, Rockwell cum Brinell, Rockwell cum Rockwell Superficial

We have Rockwell , Rockwell Cum Rockwell superficial and  Rockwell Cum Brinell Hardness Teseter in Analogue and digital version. 

These models strictly conforms to IS: 1586-2000, BS: 891 part 1 & 2 for Rockwell & Rockwell superficial test. IS: 2281-1983, ASTM-E-10 for Brinell Test.

Hardness Testers are designed and developed after years of experience in this field. All the models are manufactured under strict quality control at all manufacturing stages.

These models are suitable for testing hardness of metals and alloys of all kinds, hard or soft, whether flat or round etc. or of irregular shape. These testers are simple in design and easy to operate, still yet quite sensitive and accurate.

These models strictly conforms to IS: 1586-2000, BS: 891 part 1 & 2 for Rockwell & Rockwell superficial test. IS: 2281-1983, ASTM-E-10 for brinell test.

Rockwell System

• Automatic weight selection with automatic zero setting dial gauge.
• Automatic weight selection with automatic zero setting dial gauge with more testing height and throat

Rockwell cum Brinell Combined System

• Automatic weight selection with automatic zero setting dial gauge.
• Arrangement similar to RS with two additional weights of 185.5 kgf and 250 kgf for brinell tests.
• On this machinesmall pin having Dia 2 mm can be tested as plunger is guided with a set of six bearings.

Rockwell cum Rockwell Superficial Combined

This hardness tester is similar above machine in construction, and with automatic weight selection. This is useful for carrying Rockwell and Rockwell Superficial tests. The Rockwell Superficial method is useful for checking hardness of very thin sheets and surface hardness.

Motorized Hardness Tester models are also available in the above models.

Application and removal of major load is motorized. Motorized models have semi automatic operations for products testing. Drive motor-single phase, 230-V, 50 cycles AC.

Vickers Hardness Testers from 1 kg to 120 Kg Load . Standard Optical type, Built in Touch Screen type and Computerised version. Vickers Cum Brinell Model is also available.

This machine conforms to IS:1754-1986 for Vickers and IS: 2281-1983, BS: 240 for Brinell Test.

Vickers Hardness Tester(Vickers cum Brinell Model is also available)

• Testing range is very wide, from soft metal such as lead up to the hardest, like hardened steel
• Thin sheet metal is perfectly tested because the load applied is very small
• Same hardness number is obtained on the same specimen, regardless of the load applied.
• Built in projection screen to get accurate result

Vickers as well as Vickers cum Brinell Hardness Testers are suitable for Vickers and Brinell hardness of steel and other metals. These machined are designed and manufactured for very high accuracy, reliability and ease of operation. The selection of load is effected with the push button control system. The measurement of diagonal / diameter of indentation is done with the help of built-in optical system with graduated readout with micrometer. After taking indentation on the work piece, the objective lens is automatically swivelled into position and image of indentation appears on the focusing screen fitted in front of the machine. A push button is provided for starting the loading cycle and unloading is accomplished though hand lever.

This machine conforms to IS:1754-1986 for Vickers and IS: 2281-1983, BS: 240 for Brinell Test.
