THL380 High Precision Leeb Hardness Tester Product Overview:
THL380high precisionLeeb hardness testerIt is a new type of portable hardness testing instrument, mainly suitable for testing the hardness of metal materials. It has high testing accuracy, small size, easy operation, and convenient portability、The characteristic of wide measurement range.It is based on the principle of Richter scale and measures the Richter scale(HL)The hardness value is automatically converted into Brinell by the program、Rockwell、Vic、Shore hardness value,Various testing accessories can also be configured to meet various testing conditions and environments, mainly suitable for rapid testing of metal material hardness, especially for on-site hardness testing of large components and non removable parts.
THL380 high-precision Leeb hardness tester features:
lAccording to the principle of Leeb hardness measurement, various metal materials can be tested.
lLarge screen,adopt128×64Graphic dot matrix LCD display, rich and intuitive information,Clear displayThe screen brightness can be freely set according to the environment and lighting conditions.
lbuilt-inThermal printers,No noiseFast printing speed, able to print inspection reports on-site.
lOne host can be equipped with7Using different impact devices,Automatically identify the type of impact device,No need to recalibrate during replacement.
lFull Chinese display, menu style operation,measurementSimple and convenient.
lUSBThe interface can facilitate and quickly exchange data with a PC.standard configurationMicrocomputer software has rich functions such as transmitting measurement results, storing and managing measurement values, statistical analysis of measurement values, printing measurement reports, and batch setting instrument parameters, meeting higher requirements for quality assurance and management.
l*Bigstorable500Group (number of impacts)1~32)Hardness measurement data, each set of data includes single measurement value, average value, measurement date, impact direction, number of times, material, hardness system and other information.
lSupport "forged steel (Steel)”Material, when using D/DCWhen testing "forged steel" specimens with a type of impact device, H can be directly readBValue, no need for manual table lookup.
lThe upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be triggered if it exceeds the range, which is convenient for users to test in batches.
ltoolEquipped with EL backlight display, convenient for use in low light environments.
lEquipped with software calibration functionUsers can calibrate the instrument themselves.
lBuilt in nickel hydrogen rechargeable battery and charging control circuit;Can work continuously for no less than 150 hours; It has energy-saving functions such as automatic sleep mode and automatic shutdown.
lThere is a remaining battery indicator icon on the LCD, which can display the remaining battery level in real time; Equipped with charging process indicators, the operator can keep track of the charging level at any time.
lCompletely sealed casing, compact, portable, highly reliable, suitable for harsh operating environments, resistant to vibration, impact, and electromagnetic interference.
lDimensions: 212mm×80mm×32mm
