BH200C Leeb Hardness Tester is a simple, high-quality, ergonomic and economical Leeb Hardness Tester launched in 2019 in order to meet the needs of the market.
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, forged steel.
Features Unique support function, ergonomic design. The surface is sandblasted, with beautiful lines, corrosion resistance while increasing aesthetics, strong and durable. And it has excellent anti-electromagnetic, anti-vibration and other interference capabilities. It is a practical Hardness Tester with great value and cost performance.
Based on the Leeb hardness measurement principle, a wide range of metal materials can be inspected with high precision.
The "Steel" material is supported, and when the "Forged Steel" specimen is tested with a D/DC type impact device, the HB value can be read directly, eliminating the need to manually check the table.
It is convenient to switch to all hardness systems (HL, HB, HRB, HRC, HRA, HV, HS) and convert the measured values of each hardness system in parallel.
The large-screen 128×64 graphic dot matrix LCD display is rich in information and intuitive.
Full Chinese display, menu-based operation, simple and convenient operation.
It has a bright backlit display, which is convenient for use in low-light environments.
One main unit can be equipped with 7 different impact devices, and the type of impact device can be automatically identified. There is no need to recalibrate when replaced.
Up to 1,000 sets of hardness measurement data can be stored. Each set of data includes information such as a single measurement, an average value, the date of measurement, the direction of impact, the number of times, the material, the hardness system, etc.
The upper and lower limits of hardness values can be set in advance, and automatic alarms will be given when the range is exceeded, which is convenient for users to test in batches.
Small, portable, and highly reliable in the fully sealed plastic housing, suitable for harsh operating environments, resistant to vibration, shock, and electromagnetic interference.
The power supply adopts 2 AA (No. 5) ordinary alkaline batteries, which can work continuously for no less than 120 hours, and has power-saving functions such as automatic sleep and automatic shutdown.
There is a residual power indicator icon on the LCD, prompting the user to replace the battery in time.
It has the function of calibration of the indicator software.
The design is based on the standard: "Technical Conditions for Leeb Hardness Tester" JB/T9378-2001.
