Overview
SMART SENSOR AR936 Leeb hardness tester is a Portable Hardness testing instrument, mainly used in machine tool guide rails, automobile chassis Hardness testing, as well as installed mechanical parts, mold cavities and other small space workpieces, large workpieces multi-point rapid inspection, Pressure Vessel failure analysis, bearing production line, material warehouse distinction, heat treatment quality control and formal test records and other fields.
Features
1. It can realize the mutual conversion between six kinds of Hardness (HL, HRB, HRC, HB, HV, HS) and the mutual conversion between Hardness and tensile strength
2. Measured value, average value, date, Impact direction, number of tests, test materials, Hardness system and other rich information can be displayed
3. Support 360 ° omni-directional measurement (vertical down, diagonal down, horizontal, diagonal up, vertical up)
4. Equipped with LCD point matrix display, support Chinese and English switching and backlight function
5. Data storage with USB Interface
6. Powered by 4 * 1.5AAA battery, Working time is about 50 hours (no backlight)
7. Lightweight and Portable, Net weight only 358g, Aluminum Encasement
Principle
The Leeb hardness tester is based on the Impact Measurement principle, through the Impact device to produce an Impact on the surface of the material, the ratio of the rebound velocity and the Impact velocity of the Impact body at 1mm from the surface of the sample is measured, and the Richter Hardness value is calculated.
Applications
Machine tool guide, Hardness detection of automobile chassis, installed mechanical parts, small space workpieces of mold cavity, multi-point fast inspection of large workpieces, Pressure Vessel failure analysis, bearing production line, material warehouse distinction, heat treatment quality control, formal test records
Steps
1. Turn on and select the appropriate Measurement mode
2. Set Test Material Type and Hardness Standard
Select the Direction of Impact (within 360 °)
4. Align the Impact Device Vertically to the Test Surface
5. Apply appropriate pressure for measurement
6. Read and record measurement results
7. Storage data can be exported via USB interface
Notice
• Operating temperature range is 0~ 60 ℃, storage temperature is -20~ 70 ℃
• Impact measurement in the correct direction
• Regularly check battery level to ensure Measurement accuracy
• Avoid use in humid or corrosive environments
• Sample surface should be cleaned before measurement
• Please remove the battery when not in use for a long time
