Detailed Product Description

Product Overview

MH180 portable Leeb hardness tester, based on Leeb hardness measuring principle, quick and easy, on site test the hardness of series metallic materials, support free conversion between Leeb, Brine, Rockwell hardness scale and others, it uses high contrast segment LCD to display, small size, tight, portable, stable and reliable performance. It is widely used in failure analysis of metal processing and manufacturing, special equipment, permanent assembly, inspection and other fields. It can meet the regular hardness testing of industrial production, quality and cheap, which is the first choice for practical and economical models.

Features

l Based on the principle of Leeb hardness testing theory. It can measure many materials.
l High contrast Segment LCD , easy to use.
l One main unit can match to 6 impact devices.
l Support Steel ,when using D/DC sensor to test steel ,it can show HB directly, no need to check manually .
l Software calibration automatically.
l 100 groups (impact times 32 - 1) hardness measure value, measurement date / time, impact direction.
l Real -time display the remaining battery.
l High brightness EL back light display for easy use in dimly environment.
l Equipped with PC software (optional), with functions of measurements transmission, value storage management, statistical analysis of the measured value, the print report of measured value, batch setting instrument parameters, to meet the higher requirements of quality for activities and management.
l Tow ordinary AA batteries, it can work for not less than 100 hours; automatic screen standby, automatic sleep, automatic shutdown and other power-saving features.
l Small size, portable, stable and reliable performance, suitable for harsh environment field operations, prevent from vibration, shock and electromagnetic interference.
l Dimension:150mmx74mmx32mm.
l Weight: 245g.

Application fields

l Die cavity of molds.
l Bearings and other parts.
l Failure analysis of pressure vessel, steam generator and other equipment.
l Heavy work piece.
l The installed machinery and permanently assembled parts.
l Testing surface of a small hollow space.
l Requirements of formal original record for test results.
l Material identification In the warehouse of metallic materials.
l Rapid testing in large range and multi-measuring areas for large-scale work piece .

Application conditions

l Surface temperature can’t be overheat less than 120℃.
l Surface roughness should not to be too large, otherwise it will cause errors. The surface of the work piece must be exposed metallic luster, smoothing and polish without Oil.
l The specimens with 2-5kg or thin walled specimens overhangs should be supported with some object in order to avoid the specimen deformation, bending and movement caused by impact for medium-sized work piece ,it shall be placed on a flat and hard surface, the sample must be placed absolutely smoothly,without any shake, for heavy samples more than 5kg, it can be measured dire without any support.
l Portable Leeb hardness tester has strict requirements for sample thickness, the minimum thickness shall comply with regulatory a(see instructions).
l For work piece with hardened layer on surface,the depth of hardened layer should conform to regulatory.
l For lighter parts, please make it tightly coupled with support, two coupled surface layer should must be conform flat and to smooth, the coupling gel should not to be too much. The direction of the test shall be perpendicular to the coupling plate; if the work piece is a large plate, pole or bending material, even the weight and thickness is okay, it may still cause deformation and instability, resulting in test values error, it should be reinforced or supported at the back of the test points.
l Magnetic of work piece should be less than 30gauss.
l For artifact-surface: The work piece surface is preferably flat. When the curvature radius R of measured surface is less than 30mm, the work pieces should be tested with the small support ring the shaped support rings.

Working Conditions

l Working temperature:-10℃~+50℃,
l Storage temperature -30℃ ~ + 60℃,
l Relative humidity : ≤90%,
l The surrounding environment should avoid of vibration, strong magnetic field, corrosive medium and heavy dust.
