Built following NIST and ASTM E-100 standards. Guidelines for making hardness testing measurements directly in the Rockwell scale.  You don’t need a conversion chart, or calculation to use Ames portable hardness testers unless you are converting your results into Brinell. Here’s How to Use our Rockwell-Brinell Conversion Chart: You receive certified penetrators with every Ames Portable Hardness tester you purchase. Penetrations are of correct width and depth. Manufacturers worldwide are familiar with Standard E-100, defined by the American Society for Testing and Materials (ASTM) as the accepted parameters for hardness testing using the Rockwell method. You will receive a signed certificate with each unit which reflects the painstaking process involving 70 to 100 separate readings prior to leaving our facility.  Every Ames Hardness Tester is individually calibrated to the Rockwell scales providing authentic dependable results every time. Not Sure if You Should Use a Ball or Diamond Penetrator? Each test block supplied is certified and provided to allow you o perform accuracy checks to maintain your Ames tester. Remember annual calibration is strongly recommended for proper maintenance of your tester whether you are using it daily or annually. Always send your tester to our repair department for repairs. You can take fully-accurate readings on the inside surfaces of objects simply by switching the positions of the anvil and penetrator. Ames precision testers allow you to test directly on the plant floor.  Make sure your hardened machine cross-arms are checked before assembly.  You can test delivered metal before it even comes off the truck.  When you choose Ames, you choose accurate portable Rockwell hardness testing for every situation.

Is it time to get your Ames Hardness Tester Calibrated?

All Ames harness testers are built to meet or exceed ASTM Standard E-110  Behind each signed certificate that comes with each hardness tester is an intricate process. We calibrate each hardness tester using a process involving between 70 and 100 separate readings for standard testers and several hundred separate readings for each electronic tester. Our standard testers read in the B and C scales; the Superficial models read in the N and T scales; and the electronic models read in eight selectable scales: A, B, C, E, 15T, 30T, 15N and 30N. Accuracy checks for your AMES Hardness Testers All AMES Hardness Testers, whether you are using it constantly or not, require accuracy checks. You can easily check the accuracy by taking several readings on the test block. The readings on the barrel dial should agree with the marking on the test block. You can rely on Ames Certified Test Blocks for accurate results An important reminder, you should always apply the penetrator to the same side of the test block, on areas not marked by previous tests only. When you cannot be certain of placing the penetrator on a perfectly unaffected part of the surface, you need a new test block. Ames offers a variety of traceable, certified blocks. Ames sterilized and traceable test blocks are available in all scales. Your Ames Hardness tester should be factory re-calibrated once a year Stillion Industries provides calibration and repair services for testers manufactured by Electro Arc.  We also continue to manufacture new Ames portable hardness testers for purchase.  Hardness tester calibration verifies the accuracy of your hardness tester.  Please contact us for repair or calibration service for your tester. 7 Things you can expect when your Ames Hardness tester is re-calibrated or repaired: * You will be notified of the condition of the tester and any potential issues so that you can make a decision regarding the repair.

Your Guide to Hardness Testing Accuracy

Ames-certified test blocks assure accuracy with your Ames portable hardness tester every time.  Even if you are not using your hardness tester regularly, it still needs to be checked for accuracy.  The accuracy of Ames hardness testers is certified when you use Ames test specimens.  All Ames test specimens are traceable to national standards.   If You are Not Sure Which Test Block to Use for Accuracy Testing, Check out the Video Below: You can check your tester’s accuracy by running a test on specimens of certified hardness using the following instructions. How to check your Ames Hardness Tester’s accuracy in 6 Easy Steps: Step 1: Select the penetrator and test block. Soft materials are usually tested in the Rockwell B Scale, using 1/16″ ball penetrator and 100 Kg Major Load. Hardened steel and hard alloys are tested in the Rockwell C Scale, using a diamond penetrator and a 150 Kg Major Load. *Do not use the ball penetrator with the steel test block or when testing hard steel. Such a procedure will damage the penetrator and result in invalid tests. Step 2: Set up the tester. Secure the penetrator and the appropriate anvil in the tester. Check the position of the indicator hand. It should rest directly on the dot on the indicator dial. If it doesn’t, adjust the dial by turning the bezel to locate the dot under the pointer. Step 3: Apply Minor Load. Slowly turn the hand wheel to bring the indicator hand to the line marked “SET”. This applies minor pressure load to the penetrator. Step 4: Set the Barrel Dial. Rotate the top of the barrel dial toward you until its pin rests against the upper edge of the Lucite magnifier. The upper line of the barrel’s hardness scales should be exactly aligned beneath the hairline on the magnifier. (NOTE: There is no pin on Model 1-4). These must be aligned visually.) Step 5. Apply Major Load. Turn the hand wheel only until the dial pointer rests on the major pressure load indicated by the chart. *Be careful to bring the indicator hand exactly to the desired graduation on the dial and no farther. (Once penetration goes beyond the major load, a valid reading can no longer be obtained from that penetration. Go back to Step 2. If reading can no longer be obtained from that penetration. Go back to Step 2. If you did not stop at the major load, then go on to Step 6.) Step 6. Take the reading! Turn the hand wheel back to bring the indicator hand back to “SET” and take the reading on the barrel dial through the Lucite magnifier. Each graduation on the barrel dial indicates two points in the Rockwell scale. Standard Tester: With the diamond penetrator, read Column C on the barrel dial (black numbers). With the ball penetrator, read column B (red numbers). Superficial Tester: With either the diamond or ball penetrator, take your reading from the black-numbered N-T column on the barrel dial. (The difference n reading is created by the difference in penetrators: N with diamond, T with 1/16″ ball.) NOTE: The first two or three tests may be low until the penetrator and anvil have become firmly seated. Remember, we recommend that you have your Ames hardness tester factory re-calibrated once a year to maintain accuracy and ensure a long life for your instrument.
