This portable hardness tester uses the dynamic Leeb rebound technique, has a wide measuring range and is suitable for most metals. Displays readings in hardness scales HRB, HRC, HV, HB, HS, HL.
The AJH360 model portable hardness tester impact body, which is equipped with tungsten carbide, impacts into the work piece and rebounds back. The rebound and impact velocities are measured at the 1mm point from the work piece in the following way: the integrated permanent magnet will produce directly proportional voltage with the impact velocity. The Leeb hardness values are calculated by the following formula: HL=1000×( Vb / Va ) In Which： HL: Leeb hardness values Vb : the voltage produced during the rebound of impact body Va : the voltage produced during the impact of impact body
The new generation of portable hardness tester AJH410 offer the most affordable but accurate testing solution for on-site testing in workshops and in field operation for quality assurance. Any metal product with a minimum solid mass of 1,5 kg or more can be tested in any hardness scale. Test results appear immediately on backlit display. With software, customer also can download testing data to PC from the machine
The new generation of portable hardness tester AJH580 offer the most affordable but accurate testing solution for on-site testing in workshops and in field operation for quality assurance. Any metal product with a minimum solid mass of 1,5 kg or more can be tested in any hardness scale. Test results appear immediately on screen. With mini thermal printer, user can printe test data on project site. With software, customer also can download testing data to PC from the machine
Pen type design, self contained (Impact device and display integrated): no cables. The unique large-screen OLED color display（1.77-inch OLED Screen）integrated hardness tester in the world. Interchangeable D impact device (standard) /DL impact device (optional) can achieve one unit dual use; can be used in the restricted area measurement. With standard AAA Lithium battery compartment, battery can be replaced. Highly accuracy in any impact direction (360°), automatically identify impact direction and gravity compensation Easy Operation, the four soft keys above the screen achieve the various functions
The Unigue design portable metal hardness test of AJH720 convinces with precise measurements on most metals. It offers the same features as the common hardness test but also allows user defined hardness conversions.Max 600 groups of data can be stored in memory.USB interface. Bluetooth included, can be connected with printer through Bluetooth
AJR AUH-I portable ultrasonic hardness tester is a intelligent hardness measuring instrument. Compare with normal hardness testing device, AUH-I portable ultrasonic hardness tester adopt Ultrasonic Contact Impedance (UCI) technology AUH-I can be used in a broad variety of metals with a wide measuring range and high accuracy. AJR AUH-I also has no damage for the testing surface. AJR AUH-I model machine allows for the testing of highly sensitive on finished parts that previously could not be tested in an operational setting. The non-destructive (NDT) feature of AJR AUH-I allow the operator to accurately test parts without causing physical or structural damage that would normally lead to disposal or refinish of operators part. This translates into less scrap parts/ lower mfg costs due to necessary inspections. AJR AUH-I ultrasonic hardness tester can make measurement on any shape metal with any size like flat, round, thin or large surfaces. Accurate measurements of steel, cast steel, alloy steel, aluminum, brass, bronze and copper are easily attained with this compact instrument.
AJR AUH-II portable ultrasonic hardness tester is a intelligent hardness measuring instrument. Compare with normal hardness testing device, AUH-II portable ultrasonic hardness tester adopt Ultrasonic Contact Impedance (UCI) technology and Automatic Stabilization and Compensation (ZSC) technology. AUH-II can be used in a broad variety of metals with a wide measuring range and high accuracy. AJR AUH-II also has no damage for the testing surface. The ZSC technology also solves the traditional ultrasonic portable hardness unstable problem because of the environment and human factor.
Ultrasonic hardness tester AUH-III apply ultrasonic contact impedance method to do comparative hardness measurement for testing pieces, with advantages of high accuracy, efficiency, portable and easy operation. Ultrasonic hardness tester AUH-III is widely used to measure hardness of small forgings, cast material, weld inspection, heat affected zone, Ion-nitrided stamping dies and molds, forms, presses, thin walled parts, bearings, tooth flanks, etc.
AJR HB-3000 Electronic Brinell Hardness Tester is designed with 10 steps testing force. So AJR HB-3000 is able to measure hardness values with each 10 Brinell hardness scales. Also AJR HB-3000 hardness tester adopts circuit type loading control system. This can ensure the machine test with high precision, high repetition, and reliability and easy operation.
