The Lowl hardness meter is the first in the world designed according to the principle of the Lohl hardness test. It only needs to test the Metal hardness of the Metal hardness to test the metal hardness. It rely on the magnetic force to adsorb the measured head to the surface of the steel surface.There is no need to support the sample. The test accuracy meets the standard GB/T230 and ISO6508, which is not lower than the desktop roster hardness meter.
Local hardness meter work principle
The working principle of the Lowl hardness meter is HB450 or the sample is hourly. The British hardness test cannot be used to measure the hardness.Under the prescribed conditions, press the header (diamond cone, steel ball or hard alloy ball) into two steps into the sample surface.After removing the main test force, the remnants depth H was measured under the initial test force.Remnant depth H represents the level of hardness.This is the principle of Lobos hardness meter.One thing that users must pay attention to is that the Lowl hardness meter is applicable to products with the thickness of the measuring plate. It must be more than 1mm or more products. The round rod has a diameter of 3mm. Small products cannot be measured.

How to use the Lowl hardening meter
1. Preparatory work: Use the hardness meter that is passed after the verification; the thickness of the test parts is greater than 10 times the depth of the indentation; select the appropriate workbench according to the shape of the test piece; select the appropriate pressure head and total load number value.2. Specific steps used ① Place the test parts on the workbench, rotate the handwheel to make the workbench slowly rise, and push up the head of 0.6mm.At the mark C and B (a little bit of the dial is accurate).② After the pointer position is aligned, the patch handle can be pulled forward to add the main load to the head.
