EH860 Portable Leeb Hardness Tester is a new portable hardness tester, it is used by fast hardness testing of metal material that has specialties of accurately testing, small bulk, simple operation, convenience take, long use time, extensive measure area. It is propitious to hardness testing for large assembly and cannot strip assembly. It according to Leeb Hardness as elements that can convenient process measure for metal material and can free transition between different hardness. Product adopt occlude crust of metal that is firm and has excellent capacities of contradict magnetic field, contradict vibrancy and anti-jamming. It has advance steady COMS chip of war industry and large screen display that can collocate multifarious support ring to settle for diversified condition and environment of testing. It can equip any Special-shaped impact setting that sensor dispense with adjust and automatism identify. Mini-type portable printer time is150 hours of stay machine, mainframe has port of RS232 that can convenient process data exchange and parameter enactment with computer, 2AA Alkaline batteries for power supply that replacing is more neatly. It equip special instrument box of high intension, contradict impact, strong airproof waterproof, dampproof, dustproof, antisepsis that adapt to condition is execrable field to working.
characteristic of function
Absolute hermetic crust of metal that is small, portable and reliability, it adapt to abominable operation environment that has capability of contradict libration, contradict impact and electromagnetism disturb.
According as measure elements of Leeb Hardness that can process testing for manifold metal material. It has abroad measure area and form is not limited for workpiece, support measure direction for 360 degree and has function of value software adjust when power on, guarantee measure exactness for result within different criterion of various industries.
It support manifold hardness, (HL) , (HB) , A(HRA) , B(HRA) , C(HRA) , (HV) , (HS) . It can process switch between hardness before measure and after measure.
It dispense with adjust that automatic identify style of impact setting (D, DC, D+15, C, DL, E, G) . Seven Special-shaped setting of impact and whole series of Special-shaped support ring for satisfy the most demand of testing products in the different field.
Large screen 128W64 LCD display of graph lattice and background light support, it can adjust displays contrast for use within environment of dullish light.
Key design is humanistic, one key operation realize arbitrarily switch between material and hardness.
Mini-type portable printer take is convenient that electrical source allodium power supply, big content accumulator can 150 hours for stay machine.
It has communication port of RS232 and data processing software for connect computer that expediently process data exchange and parameter enactment with computer.
Large content can storage 500 group (impact time is 32~1 each group) measure data of hardness, data include information of single measure value, average value, date of measure, impact direction, degree, material, hardness each group. Use software connect computer for magnanimity storage.
Set hardness value upper limit and lower limit in advance, it can automatically alarm if overtop range, users can largely testing.
Support forge steel material, it can straight read HB value when use D/DC type impact setting for testing sample of forge steel, dispense with manpower to check list.
one key comeback function make instrument absolutely renew to original predicament of manufacture, never mind that error operation reflect on instrument appear questions of use.
It has functions that automatic dormancy, automatic power off and so on, low power consumption design, two AA alkaline batteries for power supply that expediently replacing and strong dependability.
Free servicing within two years (damageable piece exception) , price is reasonable of damageable piece.
