Overview
KAIRDA NDT290 Leeb hardness tester is a Portable Leeb hardness tester with a thermal high-speed printer. It is equipped with a High Accuracy D-type Sensor and a support frame. Measured values are displayed on a large and bright screen without viewing angle restrictions. The hardness gauge is a multi-functional type, which can measure 7 Hardness values such as Shore, Brinell, Vickers, Richter, and Rockwell at one time, and can be switched freely. It has a boot indication software Adjustment.
Features

2. Industrial shell design, strong and compact, easy to carry, Reliability, anti-vibration, Impact and electromagnetic interference, suitable for harsh environments.
3. The integrated design of the host and printer makes it easy to print test results on site.
4. According to the standard "Leeb hardness tester technical conditions" JB/T 9378-2001 design and manufacture.
5. Large-capacity nickel-metal hydride rechargeable batteries and charging control circuits, with remaining power indications and charging process indications to avoid overcharging.
6. Large screen OLED 128 × 64 point array display, rich and intuitive display information, no dead ends.
7. One measurement of Shore (HS), Richter (HL), Brinell (HB), Rockwell (HRC/HRB/HRA), Vickers (HV) and other 7 Hardness values, automatic conversion.
8. The upper and lower limits can be set in advance, and the limit alarm can be exceeded.
9. Optional 7 different Impact devices, no need to calibrate when replacing, automatic identification.
10. Adjustment of boot indication software to ensure accurate application of data.
11. Measured values can be stored 600 groups, full Chinese menu, backlit display, easy to operate.
12. A single charge can work continuously for at least 200 hours (when not printing), with automatic sleep and automatic shutdown power-saving functions.
13. Can be equipped with powerful microcomputer software to support transmission of results, storage management, statistical analysis, printing reports, etc.
Principle
The NDT290 Leeb hardness tester uses the High Accuracy D-type Impact device to calculate the Hardness value using the principle of Impact energy and rebound speed, automatically converts to a variety of Hardness standards, and calibrates the data through software to ensure accuracy.
Applications
Alloy tool steel, stainless steel, gray cast iron, steel and cast steel, ductile cast iron, cast aluminum alloy, copper zinc alloy (brass), pure copper, copper tin alloy (bronze), forged steel
Steps
1. Turn it on and check the battery level.
2. Select the Impact device as required and install it.
3. Measurement parameters, such as upper and lower limits.
4. Place the hardness gauge on the surface of the tested material for measurement.
5. Read and store measurement results.
6. Optional on-site printing or data transfer via USB interface.
Notice
• Avoid use in environments beyond the allowable Operating temperature range (-10~ 55 ° C).
• Pay attention to the remaining power indicator when charging to prevent overcharging from damaging the battery.
• Ensure that the automatic identification function is normal when replacing the Impact device, without Manual calibration.
Store at temperatures between -20 and + 75 ° C.
• Calibrate the indication software before use to ensure measurement accuracy.
• Pay attention to anti-shock and anti-electromagnetic interference in harsh operating environments.
