BDNDT provide all kinds of Hardness Tester in Bangladesh. OLH300 Split color screen hardness tester is a portable measuring instrument that can measure the hardness of common metal materials quickly, without damage and with high accuracy. It can be used in both laboratory and engineering site. Through the setting of instrument measurement conditions, it can meet the needs of many kinds of measurement. This instrument is widely used in manufacturing, metal processing, chemical industry, commodity inspection and other detection fields. It is a necessary instrument for nondestructive hardness testing of materials. The instrument meets the following standards: ——《JJG 747-1999 Leeb Hardness Tester 》 —— 《ASTM A956-06 Standard Test Method for Leeb Hardness Testing of Steel Products》 Product Features The probe is automatically recognized, plug and play (other manufacturers need to plug in the probe before turning on the machine). The high-performance ARM processor with Cortex-M4 core is used as the main control chip, and the processing speed is fast. Unique full-scale display all scales can be displayed on the main interface at a glance without looking up the table or switching. The Leeb hardness impact waveform display can judge the validity of the test and the working state of the impact device, such as whether the probe is worn or not, and whether there is dirt in the It can store up to 100 groups of hardness measurement data (impact times 32 ~ 1). Each group of data includes single measurement value, average value, impact direction, times, material, hardness system and other information It has USB communication interface and is equipped with upper computer data processing software as It has the function of Bluetooth printing， and the Bluetooth printer can be optionally equipped According to the principle of Leeb hardness measurement, a variety of metal materials can be The power supply adopts 2 AA ordinary alkaline batteries, which can work continuously for no less than 50 hours; it has power-saving functions such as automatic sleep and automatic The instrument is compact, portable and highly reliable. It is suitable for harsh operating environment and is resistant to vibration, shock and electromagnetic Basic Parameters Measurement direction Support for 360 º (vertical down, oblique down, horizontal, oblique up, vertical up) Measuring range (170-960)HLD (17.9-69.5)HRC (19-683)HB (80-1042)HV (30.6-102.6) HS (13.5-101.7)HRB Hardness system Leeb(HL)、Brinell(HB)、Rockwell B(HRB)、Rockwell C(HRC)、Vickers(HV)、Shaw(HS) Measuring materials Steel and cast steel, alloy tool steel, stainless steel, gray cast iron, ductile iron, cast aluminum alloy, copper zinc alloy (brass), copper tin alloy (bronze), pure copper Indication error ±0.5%(HLD=800) Indication repeatability 0.8%(HLD=800) Display Color screen Instrument size 150mm×74mm×33mm Power supply Two AA alkaline batteries in series Continuous working time About 50h Working conditions Operating temperature：-10-50℃ Storage temperature：-30℃-60℃ Relative humidity：≤90％ Serial number Type of impact device Standard Leeb hardness block hardness value Indication error Indication repeatability 1 D 760±30HLD 530±40HLD ±6 HLD ±10 HLD 6 HLD 10 HLD 2 DC 760±30HLDC 530±40HLDC ±6 HLD ±10 HLD 6 HLD 10 HLD 3 DL 878±30HLDL 736±40HLDL ±12 HLDL 12 HLDL 4 D 15 766±30HLD 15 544±40HLD 15 ±12 HLD 15 12 HLD 15 5 G 590±40HLG 500±40HLG ±12 HLG 12 HLG 6 E 725±30HLE 508±40HLE ±12 HLE 12 HLE 7 C 822±30HLC 590±40HLC ±12 HLC 12 HLC Standard Configurations Serial number Name Quantity Remark 1 Host 1 2 D-type impact device 1 3 Standard Leeb hardness block 1 4 Nylon brush A 1 5 Small support ring 1 6 AA alkaline batteries 2 7 Packing box 1 8 Random data 1
