    Model 201 Type A Durometer

    Pencil Style Durometer 

    Type A: For soft rubber and plastics

    The PTC® Analogl Pencil Style Durometers are manufactured to meet or exceed current ASTM D2240 specifications and designed to measure the indentation hardness of rubber, elastomers, and other rubberlike substances such as neoprene, silicone, vinyl, nitrile and butyl. The 360X dial features bold, easy to read numbers indicating a specific value, with a 0.2 resolution. A standard maximum hold hand retains the peak reading until reset. The durometer's 1/2" diameter base (1.3cm) is the smallest base permitted by ASTM D2240 specifications. This allows it to be used in confined or hard to reach areas other durometers cannot test.

    Model 415B Equivalent Rockwell B Scale

    The Model 415B comes complete with test block, conversion calculator, and carrying case. The unit is mounted in a stationary mill, drill press or lathe in use.
    @

    The instrument consists of a completely redesigned chassis made from aerospace aluminum, which houses a high quality displacement gauge. The upper end (the shank) is the gripping area for insertion into a milling machine, drill press, or lathe. The lower end is the load cell. It extends up into the body of the hardness tester and houses a center less ground precision spring which preloads the hardened steel indenter.

    The impression made by the indenter in the metal being tested is a very small hemisphere and is equivalent in size to a superficial examination in size. The resistance of the metal sample surface to the indenter results in the gauge pointer being moved to a corresponding hardness reading. Minimum sample thickness is 0.025" for most materials. If the indenter does not make a dimple on the opposite side, the material is thick enough for accurate testing.
    @

    The Model 415B is designed for use by inspection and quality control personnel, heat treaters, tool and die makers, mechanics, welders, etc. This unique instrument is the handiest and the most economical way of grading and checking various metals in equivalent Rockwell B range of 40HRB to 100HRB

    Specifications:

    • Range 40 HRB to 100 HRB (equivalent Rockwell B Scale).
    • Accuracy 1.5 points.
    • Weight (instrument only) 12 oz. (340 g ) with case & block) 1 lb. 1 5 oz. (. 9 kg).
    • Shipping weight 4 lbs. (1.8 kg)

    @

    The impression made by the indenter in the metal being tested is a very small hemisphere and is equivalent in size to a superficial examination. The movement of the indenter into the hardness tester causes the gauge pointer to read the corresponding Rockwell C Scale hardness.
    @

    Minimum sample thickness is 0.025" for most materials. If the indenter does not make a dimple on the opposite side, the material is thick enough for accurate testing. The Model 415C is designed for use in machine shops, laboratories; and by inspection and quality control personnel, heat treaters, tool and die makers, mechanics, welders, metallurgists, etc.

    Measurement Principle

    The Handy Hardness Tester model SH-21 differs completely from traditional hardness testers. Instead of measuring the size of the indentation of the test sample using a microscope, it uses a diamond indenter equipped with a vibrating rod that presses on the test surface at a fixed load and then measures its hardness by applying ultrasonic vibrations and analyzing its damping effect. When the vibration rod is applied to a soft-surfaced test sample with identical qualities and at a fixed force, it makes a deep indentation and gets locked into the groove. Due to this, the resonance frequency increases. Conversely, it does not get locked in when used on hard test samples and the resonance frequency drops. The test sample's hardness can be calculated using the correlation between this deviation and the tested hardness.

    Portable Metal Hardness Tester

    The Webster Hardness Testers are a portable, fast, accurate hardness gauge that are made in three distinct models for testing Aluminum, Brass, Copper and Mild Steel. Webster Hardness Testers will quickly identify tempers and test a variety of shapes that other testers cannot check, such as extrusions, tubing and flat stock.

    All testers operate in the same manner but differ only in penetrator design, type of load spring and hardness ranges. The principle of operation is simple. The work to be tested is placed between the anvil and the penetrator. Pressure is then applied to the handles until "bottom" is felt at which time the dial indicator is read.

    Model B

    The Model B Tester is designed to cover the hardness of aluminum alloys from the 100 to the 7075 series. The 20 graduations on the Webster dial indicator covers the range between 25 and 110 on the Rockwell E Scale.

    @

    Model B-75

    The Model B- 75 Tester was developed to obtain more sensitive response to slight changes in the upper range of hardness covered by the Model B. This sensitivity is particularly useful in testing mild steel and the stronger aluminum alloys. For brass the B-75 covers the range from annealed to full-hard. This added sensitivity is accomplished by incorporating a penetrator of slightly different contour and a heavier load spring than used in the Model B. The 20 graduations on the Webster dial indicator covers the range between 20 and 100 on the Rockwell B Scale.

    @

    Model BB-75

    The Model BB-75 Tester was developed to answer the need of certain industries for a method of rapidly testing the hardness of electro-deposited copper in the low hardness range. The B-75 penetrator is used to give sensitivity, and the Model B load spring is employed to give light pressures. This combination allows the user to test the soft range of many common materials. The graph below shows the range covered by the Model BB-75 tester on copper.
