Product Description
Product Overview
MH660 portable Leeb hardness tester is our latest upgrade model,it focuses on user experience and innovative features.Using 320 x 240 color LCD display,can also present clear measurement results in dim light and strong sunlight environment,greatly enhance the visual experience; sealed metal case compact design,smaller,better quality,designed to withstand harsh field environment of the oil,dust,more original point calibration function is used to do multi-point calibration for convert curve to reduce errors;during measurement instrument can automatically identify the measuring direction,automatically alarm when out of rage,to meet the inspection requirements with high precision and multi-angle material collected,support free conversion between hardness type;low-power design powered by two AA batteries,support multiple languages.Blue-tooth printer.It is widely used in metal processing and manufacturing,special equipment and permanent component failure analysis in service,inspection and other fields.Particularly suitable for large non-removable part of the site hardness testing.It is to improve the pass rate of production and cost savings necessary professional precision instrument.

Features
Based on the principle of Leeb hardness testing theory. It can measure many metallic materialsOne main unit can match to 6 impact devicesAutomatically identify the state of impact devices(connect, disconnect, error, etc)Automatically identify the direction of impact devices(except G),360°,comprehensive free measurement.320 x 240TFT LCD screen, information-rich, intuitive, clear, display, adjustable brightness, easy to use in dimly litBasic (single-point )calibration and multi-point calibration function for convert curve, to reduce the test errorHardness scales can to convert to HL,HRB,HRC,HRA,HV,HS.Built-in Leeb Hardness conversion function to converse HLD to HLC,HLG,HLDL,HLD+15,which is convenient for calibration and value conversionPreset up and low limit of hardness value ,it will alarm automatically if out of range alarm, convenient for batch testings Chinese-English converting, menu operation, easy and convenientIt can store 500 groups (impact times 32 ~ 1) hardness measurements, each set of data includes single testing value, average value, measurement date / time, impact direction, frequency, material, hardness, and other information.Tow ordinary AA batteries, it can work for not less than 100 hours; automatic screen standby, automatic sleep, automatic shutdown and other power-saving featuresWith field-portable mini-printers with Blue-tooth communications, convenient to generate data reportsUSB interface can do transmission measurements, value storage management, value statistical analysis, printing the value report and batch setting the instrument parameters through the PC data-pro software to meet the higher demand for quality.Dimension:120mm×67mm×31mmApplication fieldsDie cavity of moldsBearings and other partsFailure analysis of pressure vessel, steam generator and other equipmentHeavy work pieceThe installed machinery and permanently assembled partsTesting surface of a small hollow spaceRequirements of formal original record for test resultsMaterial identification In the warehouse of metallic materialsRapid testing in large range and multi-measuring areas for large-scale work piece
