Surve No. 682/1, Bhosari, Pune - 411039
Manufacturer, Supplier of Rockwell Hardness Testing Machines
We are Manufacturer, Supplier, Distributor, Trader, Exporter, Importer of Optical Vickers Hardness Testing Machines (Hardness Testers) and our set up is situated at Pune, Maharashtra, India.
VHT-50 Testing range is very wide, from soft metal such as lead, up to the hardest, like hard steel. Having facility to connect many objectives in single machine. Sharp Indentation clarity getting by adjusting advanced light integration technology. Loading and unloading cycle is motorized. Thin sheet metal is perfectly tested because the load applied very small. (Built-in projection screen to get accurate results from analyzing chart as manually.)
VHT-50 D Testing range is very wide, from soft metal such as lead, up to the hardest, like hard steel. Same hardness number is obtained on the same specimen, regardless of the load applied. The indication is tiny and allows testing of a precision finished part. Loading and unloading cycle is motorized. Depth measuring facility. (Built-in projection screen to get accurate results automatically on HMI Screen as Digitally)
Application :STM Vickers Hardness Tester is a simple and accurate means to produce and measure the diamond indentation. These testers are suitable for measuring the hardness of precision metallic parts with wide testing range - from soft to hard and their accurate results are widely acclaimed. These testers strictly confirm to IS: 1501-2 and ISO 6507-2

Construction :
The robust machine frame is designed to accommodate the high precision loading system and an
optical projection screen.
Specimen 1s placed on a testing table. The test cycle is fully automatic.
The accurate load is applied on a diamond indenter by means of a lever and weights. After specific
laps of time, the load is removed automatically.
The objective is indexed with the test piece and the diamond indentation is projected on the
measuring screen.
The diagonals of the indentation can be measured by means of the micrometer thimble of the
projection screen.
