Overview
The PORUIKE BH-200C High Accuracy Leeb hardness tester is a Portable Hardness Measurement instrument designed according to the Richter Hardness Measurement principle. It supports High Accuracy testing of a variety of metal materials and can convert measurements in parallel between different Hardness standards. It is suitable for a variety of industrial sites and laboratory environments.
Features
1. According to the Richter Hardness Measurement principle, a variety of metal materials can be tested for High Accuracy.
2. Support "forged steel (Steel) " material, and the HB value can be directly read when testing with D/DC type Impact device, without manual table checking.
3. Easy to switch to all Hardness formats (HL, HB, HRB, HRC, HRA, HV, HS), and convert each Hardness measurement value in parallel.
4. Adopt large screen 128 × 64 graphic point matrix LCD, rich information, intuitive, full Chinese display, menu operation, simple and convenient operation.
5. With a bright backlight display, it is convenient to use in a gray environment with rays of light.
6. One main engine can be equipped with 7 different impact devices, automatically identifying the type of impact device, and no need to re-calibrate when replacing.
7. It can store up to 1000 sets of Hardness measurement data, each set of data contains single Measured value, average value, measurement date, Impact direction, number of times, material, Hardness system and other information.
8. The upper and lower limits of Hardness value can be preset, and the automatic alarm beyond the range is convenient for batch testing.
9. Fully sealed plastic shell, small, portable, Reliability, suitable for harsh operating environment, anti-vibration, Impact and electromagnetic interference.
10. The power supply adopts 2 AA (No. 5) ordinary alkaline batteries, which can work continuously for not less than 120 hours, and has power-saving functions such as automatic sleep and automatic shutdown.
11. There is a remaining power indicator icon on the LCD, prompting the user to replace the battery in time.
12. Adjustment of indication software.
Principle
The hardness gauge works according to the Richter Hardness Measurement principle. The instrument uses the Impact body in the Impact device (e.g. D type) to impact the surface of the sample at a certain speed under the action of elastic force, and measures the ratio of the rebound velocity of the Impact body at a distance of 1mm from the surface of the sample to the Impact velocity. The ratio is defined as the Richter Hardness value. The measured basic Richter Hardness value (HL) can be converted to the Miscellaneous common Hardness standard (such as HB, HRC, etc.) through the built-in program of the instrument.
Applications
Installed machinery or permanent assembly parts, mold cavities, heavy workpieces, Pressure Vessels, turbo-generator sets and their equipment failure analysis, Test space is very small workpieces, bearings and other parts, requiring formal original records of test results, metal material warehouse material distinction, large workpieces in a wide range of rapid inspection of multiple measurement parts
Standards
"Leeb hardness tester technical conditions" JB/T 9378-2001
Steps
1. Select the appropriate Impact device according to the tested material and install it on the main engine.
2. When turned on, the instrument automatically recognizes the type of Impact device.
3. Select or set parameters such as material type and Hardness standard in the menu.
4. Press the Impact device vertically (or in the allowable direction) on the surface of the workpiece to be tested, and press the release button for measurement.
5. Read the measurement results displayed on the LCD screen.
6. Multiple measurements can be made, and the instrument will calculate and display the average value.
7. The measurement data can be automatically stored, and the over-limit alarm can be carried out by setting the upper and lower limits.
Notice
• Please ensure that the instrument is fully charged before use.
• Please select the impact device and setting material type correctly according to the material being tested.
• Make sure that the Impact device is pressed against the measured surface during measurement, and the Impact direction should be within the allowable 360 ° range.
• The instrument should be used and stored under the allowable Operating temperature (-10~ 55 ℃) and Humidity (≤ 90%) environment.
• Avoid use in environments with strong electromagnetic interference, severe vibration or Impact, so as not to affect the Measurement accuracy or damage the instrument.
• When not in use for a long time, please remove the battery.
• The instrument has indication software Adjustment, it is recommended to calibrate regularly to ensure measurement accuracy.
• When replacing the Impact unit, there is no need to re-calibrate, but make sure it is installed in place and correctly recognized by the host.
