Overview
KAIRDA NDT230 is an economical Portable Leeb hardness tester with a hard plastic shell, mature technology and support for batch testing. The hardness gauge can be configured with 7 different Impact devices for the measurement of various hardness of materials, supports software calibrating and tolerance setting, especially suitable for out-of-office detection of mold cavity Hardness. Measurement accuracy is high, Reliability is good, standard D-type Impact device. Materials for measurement include steel and cast steel, alloy tool steel, gray cast iron, ductile cast iron, cast aluminum alloy, copper-zinc alloy (brass), pure copper, forged steel.
Features
1, the use of fully sealed plastic shell, with anti-vibration, anti-electromagnetic interference and anti-Impact ability
2. Simple and intuitive menu operation, one-button arbitrary switch material and Hardness system
3. Freely convert all Hardness formats (HL, HB, HRB, HRC, HRA, HV, HS) without manual calculation
4. Can be equipped with 7 different Impact devices, automatically identify different devices, no need to re-calibrate when replacing
5. Low power consumption design, with automatic sleep, automatic shutdown, and remaining power prompt functions
6. Support "forged steel (Steel) " material, HB value can be directly read when tested with D/DC type Impact device, no need to manually look up the table
7. Use a No. 5 ordinary battery to work continuously for at least 200 hours
8. Adjustment of boot indication software to ensure accurate application of different specifications and standards
9. With automatic alarm function, tolerance limits can be preset, and automatic alarm beyond the range is suitable for batch testing
Principle
The NDT230 Leeb hardness tester adopts the Impact device Measurement principle, which produces Impact rebound on the surface of the sample by the Impact body, and obtains the Richter Hardness value by measuring the ratio of the rebound speed to the Impact speed, and automatically converts it into a variety of Hardness standards.
Applications
Machining industry, mold cavity, bearings and other parts, heavy workpieces, workpieces with small experimental space, on-site hardness testing of large parts and non-removable parts, Pressure Vessel, failure analysis of turbo-generator sets and their equipment, material differentiation of metal material warehouses, rapid detection of multiple measurement parts in a large range of large workpieces
Steps
1. Turn on and select measurement material and Hardness standard
2. Install the appropriate Impact device (automatic equipment identification)
3. Set tolerance limits (optional)
4. Impact device vertical contact sample surface for measurement
5. Read the Hardness value on the display
6. Automatic alarm when the equipment exceeds the tolerance range
7. After the measurement is completed, the stored data can be viewed
Notice
Working environment should be no vibration, no strong magnetic field, no corrosion medium and serious dust
• Operating temperature -10~ 55 ℃, storage temperature -20~ + 75 ℃
• Allowable relative humidity ≤ 90%
• The measurement direction can be arbitrary (360 °)
• Powered by 2 1.5V ordinary alkaline batteries
• Measurement accuracy by regularly calibrating the software
• Pay attention to the battery level prompt and replace the battery in time
