Dor Yang Mh320 High Precision Portable Leeb Hardness Tester

One, overview:
Dor Yang MH320 portable Leeb hardness tester based on Leeb hardness measurement principle, can be easily and quickly measured on a variety of metal materials, instantly showing the hardness values measured at the same time, can be in a variety of hardness of system's (Brinell Rockwell HRC, Vivtorinox HB, HV, Shaw HS) free conversion can be pre-set tolerance limit, beyond the range of automatic alarm. Integrated design of the host and high speed thermal micro printer products, imported high-speed printer support on-site print function, print paper to ensure long-term import data stored for a long time. Low power design idea based on IC integrated circuits, with large capacity, long life, fast charging of nickel hydrogen battery. The Chinese menu display, operation is simple and convenient, seven kinds of special-shaped impact device without the need for calibration, automatic identification, the USB interface transmission, large storage capacity, and with a PC machine humanized data processing software.
Two, the technical parameters:
The purpose of measuring range: (170-960) HLD, (17-68.5) HRC, (19-651) HB,
In the measuring direction: vertical, oblique, under the support of horizontal, vertical, oblique
 
The purpose of measuring material: steel and cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, aluminum alloy, copper zinc alloys (brass), an alloy of copper and tin (bronze), copper, forged steel
The purpose of hardness standards: magnitude (HL), (HB) Brinell, Rockwell Rockwell B/C (HRB/C), A (HRA), Vivtorinox (HV), Shaw (HS)
It showed that the dot matrix LCD, 128 * 64 dot matrix LCD
The purpose of data storage: a maximum of 500 groups (impact number 32 ~ 1)
In the thermal printer, quiet operation, the test results can be printed in any number of copies, to meet the needs of field
The purpose of the print paper width: (57.5 + 0.5) mm; printing roll diameter: 30mm
operating voltage: 6V battery; charging power supply: 9V/500mA charging time 2.5 to 3.5 hours;
In the continuous working time: about 150 hours (not print, do not open when backlit); communication interface standard: USB1.1
Three, applicable materials:
Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, nodular cast iron, aluminum alloy, copper zinc alloys (brass), an alloy of copper and tin (bronze), copper, forged steel
Four, the working conditions:
Ambient temperature: the temperature - to which C; storage temperature: -30 ~ 60 relative humidity is less than or equal to 90% DEG C;
The environment without strong vibration, no strong magnetic field, non corrosive medium and serious dust.
Five, the characteristics of the product:
- on the basis of Leeb hardness measurement principle, can be used to detect a variety of metal materials; software calibration function.
- a host can be equipped with 7 different impact device, automatic identification of impact device types, replaced without the need to recalibrate.
L support "forged steel (Steel) materials, when used with D/DC impact device test" forged steel sample, can be directly read HB, without the need for manual look-up table.
The hardness values can be preset, the lower limit, beyond the range of automatic alarm, convenient batch testing needs.
- the big screen 128 * 64 dot matrix liquid crystal display, intuitive, information rich.
- the Chinese display, menu operation, simple and convenient operation. EL backlight display, convenient to use in dark environment.
The largest group of 500 stores (impact number 32 ~ 1) hardness measurement data, each set of data includes a single measured value, average value, the measurement date, the impact direction, number, material, hardness of system information.
The thermal printer and apparatus are integrated into a whole, quiet operation, fast printing speed, can print test report.
- built in rechargeable battery and a charging control circuit; can work continuously for not less than 150 hours; automatic shutdown and automatic power saving function, dormancy.
- LCD battery indicator icon, real-time display the remaining battery power; charging indicator, the operator can know the degree of charge.
There is a USB interface, can easily, quickly and PC for data exchange. Can be equipped with computer software, with transmission measurements, measured value storage management, statistical analysis, measurement, measurement report print batch set the parameters of the apparatus, rich functions, meet the higher requirements of the quality assurance and management.
This instrument is small, portable thermal printer can print, size: 212mm * 80mm * 32mm
