Type : 7005 (With PC Interface and Measurement Software)
Description
The instrument comprises of a microscope alongwith a Filar micrometer eye piece of 10X and objective of 40X. The instrument is mounted on a stand having loading and unloading mechanism attached to the microscope. A standard weight of 10 gms to 200 gms is loaded on the indentor assembly. An indentation, with the help of a diamond indentor, is caused on the material of the surface (whose hardness is to be measured). The system employs a high precision rotating specimen table (fitted with micro meter screw gauges) to turn the sample under the microscope along X and Y axis.
Features
First ever Indian instrument (Import Substitute) designed in collaboration with the Central Scientific Instruments Organisation, Chandigarh.
Low cost opto-mechanical instrument.
Micro hardness measurement in vickers.
Easy to operate
Repeatability in results
Principle
The principle of operation of the instrument is based on pressing a diamond indentor into the specimen under test with a certain load in gms and consequently measuring linear
value (d) of the diagonal of the indentor print obtained.
The hardness number (H) is calculated by dividing the load (P in Kg) by the surface area (S in sq mm) of the
indentor print and is expressed as H = P/S or 1.854 P/dą.

Type : MHB - 3000
MHB-3000 is an advance digital Brinell Hardness TEster based on the technology of DBH 3000HBE 3000. It has auto indentation reading system by means of 20X portable Brinell microscope and digital lenght sensor. It does not need read the detail length of indentation, only need operators aim the tangent of indentation out of anvil and then press the button of sensor and the lenght will be imput into the instrument processor and it will compute hte output the brinell value automatically. It is a convenient , rigis and affordable Brinell HArdness Testing Machine.
Portable Leeb HArdness Tester MH 320 is used widely in on site hardness testing, with menu driven, large memory capacity, USB port connect with computer, software to store and analysis its test data, standard compositive mini-printer for on site printing.
