Support 360o (vertically downward, oblique, horizontal, oblique, straight up) Hardness standard:? Leeb (HL), Brinell (HB), Rockwell B (HRB) ?, Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), Shore (HS) Display: dot matrix LCD, 128 × 64 dot matrix LCD Data storage:? maximum 500 groups (impact times 32 to 1) Operating voltage:? 3V (2 AA-size alkaline batteries in series) Continuous working time:? about 50 hours (without backlight time) communication interface standard:?? USB1.1 Third, the application materials: steel and cast steel, alloy tool steel, stainless steel, gray iron, ductile iron, cast aluminum, copper and zinc alloy (brass), copper-tin alloy (bronze), copper, forged four working conditions: Ambient temperature: Operating temperature -20 ~ + 60 ℃; Storage temperature: -30 ℃ ~ + 60 ℃ Relative humidity ≤90%; the surrounding environment without a strong vibration, no strong magnetic, non-corrosive medium and severe dust. ? V. Product Features: fully sealed metal enclosure, compact, high portability, reliability, suitable for harsh operating environment, anti-vibration, shock and electromagnetic interference ability is strong, durable; based Leeb hardness measuring principle, can? detect a variety of metal materials. Measuring a wide range, there is no limit on the measurement of the workpiece shape, support 360 o measurement direction, and has shown the value of software startup calibration function, to better ensure accurate data applicable in any industry with different norms and standards. ? S system supports a variety of hardness Leeb (HL), Brinell (HB), Rockwell B (HRB), Rockwell C (HRC), Rockwell A (HRA), Vickers (HV), Shore ( HS). Before and after measurements can be carried out in parallel to measure the hardness of the system's conversion between. ? Excellent compatibility, seven kinds of impact device automatically recognizes no need for calibration. Shaped impact device and a series of special-shaped support ring and reasonable price to meet the greatest needs of different customers in different areas. ? All Chinese large-screen LCD 128 * 84 dot matrix LCD with EL backlight support, easy to use in dimly lit environments. ? Host panel full Chinese menu operation, circuit design embodies the concept of humanity, one-button switch achieve any material and hardness of the system's simple and convenient. ? With a USB plug and play interface, the standard configuration comes with a PC connected to the computer data processing software, you can quickly and easily with the PC for data exchange and parameter settings. ? Large capacity storage of up to 500 groups (impact times 32 ~ 1) hardness measurements, each single measurement data including value, the average measurement date, impact direction, the number of materials, hardness, and other information. Connected to the computer using the software can achieve mass storage.? Hardness values ??can be pre-set lower limits, out of range alarm, facilitate the needs of users to batch testing. ? Support "forged steel (Steel)" material, when using D / DC type impact test "forged" sample, it can directly read the HB value, without manual look-up table. ? Has automatic sleep, automatic shutdown and other energy-saving features, low power design, 2 AA AA batteries, easy to replace, battery reliability stronger. ?
