Due to the wide range of applications of the Leeb hardness tester, the market demand for the Leeb hardness tester is also increasing. Many manufacturers have gradually joined the market competition of the Leeb hardness tester. Due to the relatively loose production standards for the Leeb hardness tester, the quality and price of the Leeb hardness tester vary. When you buy a Leeb hardness tester, you will often encounter Leeb hardness testers with the same or similar functions. If you inquire from different manufacturers, the quotations you get will vary greatly. So, how to choose the Leeb hardness tester?
The measurement of the Leeb digital hardness tester machine is carried out by the impact device. Because the measured workpiece and the environment are unpredictable, the Leeb hardness tester has corresponding different types of impact devices and supporting rings according to different measurement environments and workpiece specifications. When purchasing a Leeb hardness tester, you should first consider Leeb hardness testers that can use different types of impact devices, so as not to be unable to use them in special circumstances later.
The working principle of the hardness measurement tool is to use an impact head to impact the surface of the tested workpiece, and obtain the hardness value of the tested workpiece through the rebound speed of the impact head. Then, under the condition of long-term work, the impact head will produce some loss. If the worn impact head is used for testing, the hardness value test result obtained will inevitably have errors. Therefore, when you choose the Leeb hardness tester, you must confirm whether the matching impact device can replace the impact head.
The digital hardness testing machine is a kind of testing equipment. So, when choosing a Leeb hardness tester, one of the important factors is whether the accuracy of the equipment meets the requirements. When the Leeb hardness tester detects the hardness, its use environment is unpredictable, but if the accuracy of the Leeb hardness tester used is very high and the user performs the test in accordance with the operating requirements, the hardness value obtained will be more accurate.
The Leeb hardness tester is mainly used on the construction site or for testing large workpieces. The general testing environment is factory workshops, construction sites, etc, which is relatively harsh. When testing the hardness, it is particularly important to save the data in time. The quality requirements of the Leeb hardness tester itself are also relatively high. When you are purchasing a Leeb hardness tester, you must confirm the data storage method of the Leeb hardness tester and the material used by the Leeb hardness tester.
