MH660 portable Leeb hardness tester is Mitech latest upgrade model, it focuses on user experience and innovative features. Using 320 × 240 color LCD display, can also present a 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 range, 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 or 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.
Working Principle
The basic principle is to use an impact body of certain weight impacts against the testing surface under certain test force, then measure the impacting velocity and the rebounding velocity of the impact body respectively when the spherically test tip is located 1mm above the testing surface.
The calculation formula is as follows:
HL=1000×VB/ VA
Where:
HL—— Leeb hardness value
VB—— Rebounding velocity of the impact body
VA—— Impacting velocity of the impact body
Basic (single-point) calibration and multi-point calibration function for convert curve,to reduce the test error.
Hardness 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 conversion.
Preset 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 convenient.
It can store 500 groups (impact times 32 ~ 1) hardness values, each data includes single testing value, average value, measurement date / time, impact direction, frequency, material, hardness and other information.
Two ordinary AA batteries, it can work for not less than 100 hours; automatic screen standby , automatic sleep, automatic shutdown and other power-saving features.
With field-portable mini-printers with Bluetooth communication, convenient to generate data reports
USB 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 sealed aluminum-magnesium alloy metal shell, compact, high portability, reliability, designed for harsh field environments, rugged, unique seal design allows it to resist wet , sand, dust, oil and other contaminants of harsh environments from the ocean to the desert
Dimension:120mm×67mm×31mm
