Webster Model B Portable Hardness Tester w/Case & New Cal Cert (WORKS GREAT!)

Description: Webster Model B Portable Hardness Tester w/Case & Accessories (WORKS GREAT!) Comes with a new calibration certificate and sticker. Calibration will be performed at time of purchase, and a new calibration certificate and sticker will be provided with the tester. Your information (Name/Company, ID#, Cal Interval) can be on the certificate if you'd like as well. Tester appears to be in great working order, and is in pretty good cosmetic condition. It's been checked with the test strip and 3 different Rockwell test blocks and found to be accurate and repeatable throughout its range. Cosmetically there is some minor wear and scratching. There is a crack in the plastic over the dial in the very edge/corner. The pin anvil has some discoloration that looks like corrosion but the finish is still smooth. The rubber part of the handle is a bit chewed up. The case is in decent shape, the foam isn't deteriorating yet, but there is some rust on the latch and hinges and dirt on the outside. There is a bit of rust on one side of the adjustment wrench as well. The test patch has just over half it's space free I'd say. See photos for cosmetic detail. Included in this auction is the Webster model B hardness tester, test strip for checking the tester, adjustment wrench for adjusting the tester, the owners manual, and two supplementary printed documents. Everything is held inside the original Webster case. ---- From Manufacturer Information ---- A portable tester for testing materials such as aluminum, brass, copper, and mild steel. Quickly identify tempers. Tests a variety of shapes that other testers can't check: Extrusions, Tubing and Flat Stock. The Model B tester was designed to cover the hardness of aluminum alloys from the 1100 to the 2024 series in 20 graduations of the dial indicator. This range lies between E 25 and E 110. -One hand operation and portability.-Round 3/8 inch diameter anvil permits testing a great variety of shapes.-Simple and rugged operation and construction -Ability to test materials up to 1/4 inch in thickness-Test is made by simply applying pressure to the handles until "bottom" is felt.-Easy-to-read dial indicator with 20 graduations converts to standard hardness scale, or can be used as "go" and "no-go" gauge.-Standard hardness gauge tests materials between 0.025" and 1/4" wall thickness. The penetrator housing, which contains the penetrator and load spring, slides vertically in the frame of the tester when pressure is applied to the handles. Only sufficient pressure is needed to "bottom" the lower face of the housing against the work. Resistance of the work to the penetrator causes the penetrator to recede into the housing against the spring pressure. The degree of penetration on the test specimen is indicated on the dial indicator sitting on top of the housing assembly. The load can be varied by adjusting the nut above the load spring, permitting the dial reading to be easily corrected against a test block of known hardness. A penetration of .010 inch produces a full scale reading on the dial indicator. Therefore materials in the softer hardness range should be of sufficient thickness so that the anvil will not influence the test and produce an "anvil effect". In general, soft materials under .025 - .030 in thickness will not give true readings.
