Overview
The IPRE PRLH320 Leeb hardness tester is a Portable hardness testing instrument that can be equipped with a variety of Impact devices, automatically identify the type of Impact device, and support the conversion between various hardness standards and tensile strength. It has a built-in thermal printer, supports Bluetooth transmission and wireless printing, and can be managed by the upper computer software.
Features
1. Can be equipped with 7 different impact devices, allowing for automatic identification of the type of impact device.
2. Embedded thermal printer, hardness testing report timely printing.
3. It can realize the mutual conversion between 6 kinds of hardness (HL, HRB, HRC, HB, HV, HS) and the mutual conversion with tensile strength.
4. Rechargeable lithium-ion battery, automatically detects battery voltage and provides low-voltage warning.
5. Support Bluetooth transmission and wireless printing.
6. Optional host computer software, with complete database functions, supports data query, storage, statistical features, and histogram display.
7. Rich status bar displays Bluetooth, buzzer, error message, time, battery level and other status.
8. Support calibrating under a variety of hardness systems.
9. Software can be upgraded online.
Principle
The Leeb hardness tester works based on the principle of Leeb hardness testing. The impact device ejects the tungsten carbide ball to the surface of the material to be tested, and the ratio of the rebound velocity of the impact body to the impact velocity at a distance of 1mm from the surface of the sample is measured. The ratio is related to the material's Leeb hardness value. The instrument automatically calculates and can be converted into Miscellaneous hardness scale or tensile strength value according to the preset program.
Applications
Mold, Heat Treatment, Machining, Pressure Vessel, Auto Parts, Aerospace, Universities, Research Institutes, Technical Supervision, Special Inspection Institute
Steps
1. Select the appropriate Impact device according to the tested material and install it.
2. When turned on, the instrument will automatically identify the type of Impact device.
3. Set the test material, hardness and other parameters.
4. Press the Impact device vertically or in the permissible direction against the surface of the tested material.
5. Press the release button to test, read or store the hardness value.
6. Test reports can be printed through the Built-in Printer, or data can be transferred to a computer or wireless printer via Bluetooth.
Notice
Before testing, the instrument parameters should be set correctly according to the type of material.
● Ensure that the Impact device is perpendicular to the measured surface or in the measurement direction allowed by the instrument.
● The tested surface should be flat, smooth, clean, and have sufficient Film thickness and mass.
Regularly calibrate the instrument to ensure measurement accuracy.
● Pay attention to the battery level and charge it in time when the battery is low.
● Avoid use in strong electromagnetic interference environment.
● Impact devices are precision components and should be protected from bumps and drops.
