This model strictly conform to Standards:ASTM D2583 Barcol Hardness Tester for testing the hardness of materials acc. to ASTM D2583. Originally called the Barber-Colman Impressor, the Barcol impressor was developed by Walter Colman as a hand-held, portable means of assessing the hardness of a material during World War II. The United States Army Air Corps required a hand-held method of checking the hardness of rivets due to concerns that aircraft could be sabotaged by replacing normal rivets with soft lead or wooden ones which would fail during flight. The impressor operates when the tip is pressed against the material in question. The hardness of the material determines how far the tip indents and this is transferred by a tension spring and lever to be read on a dial

 Light Weight, fast, reliable and easy to hold digital portable hardness Tester covering widest measuring ranges for metals.

 A Carbide tipped impact body of definite mass is impacted on the surface of specimen. A part of this energy is obsorbed by the specimen. the hardness value is the ratio of rebound energy and impact velocity and is displayed on LCD Screen in HLD Unit.

The machine has built-in conversion facility to convert HLD value into Vickers, Rockwell, Brinell Scales

W20 Testing Range 25-110HRE,58-131HV , Thinkness(mm): 0-20HW,0.6-6, Inner diameter>101.Webster Hardness Tester is a portable instrument which can perform on-site hardness testing on soft materials.By a quick and easy test,the hardness value can be read out directly with a simple clamp,in accordance with American Standard ASTM B647 2.used to check the result of hest treament and determine if the mechanical performance of the workpiece is acceptable3.A test can be completed by one press. 4.Model W-20 equivalent to US Model B Tester 5.Very fast, very simple and very portable,small indentation. 6.Suitable for testing the hardness of aluminium profiles, tubings,sheets and other shapes7.Used for testing the with long or heavy workpieces or assemblies inconvenient to be sent to the labs. 8.Used to check the result of heat treatment and determine if the mechanical performace of the workpiece is acceptable. 9.The Webster hardness value can be converted into the common-used Vickers,Rockwell and Brinell hardness value. 10.Different models available for testing aluminum alloys,brass,copper alloy andcopper.

The Barcol hardness test characterizes the indentation hardness of materials through the depth of penetration of an indentor, loaded on a material sample and compared to the penetration in a reference material. The method is most often used for composite materials such as reinforced thermosetting resins or to determine how much a resin or plastic has cured. The test complements the measurement of glass transition temperature, as an indirect measure of the degree of cure of a composite. It is inexpensive and quick, and provides information on the cure throughout a part.The Barcol Tester is a small portable Hardness Tester having a weight around 1 Kg.It is suitable for testing hardness of aluminium, aluminium alloys, copper, brass, plastics, fiber glass and other soft materials having hardness from 25 to 150 BHN (10 mm ball / 500 kg load).No experience required; can be used in any position and in any space that will allow for the operator\'s hand. The hardness reading is instantly indicated on the dial, which is divided into one hundred graduations. No waiting, pre-loading or separate measurements. Easy to UseSingle hand operation which gives easy flexibility to use the instrument without much efforts. As it is portable it can be used for testing at any place and at any direction.  High SensitivityBarcol Hardness Tester has 0 to 100 scale. Least count 1 division (0.5 on request). Sensitivity is higher than that of Webster Hardness Testers.  Wide Testing RangeIt can test from pure aluminium to super hard aluminium alloy, reinforced platics, hard plastics, laminates, FRP, Resins, fiber glass materials, Barcol hardness Tester is used for fiberglass, storage tanks, artificial marble.  IndenterThe material hardness of indenter and dimensional tolerance are as per ASTM D2583.  Hardness BlocksIt can ensure the accuracy, repeatability, and uniformity of the measurement results. Barcol Hardness Tester Conversion ChartThrough the Barcol hardness conversion table, Barcol hardness value can be conveniently converted to Brinell, Rockwell, Vickers and Webster hardness values.
