Pin Impact Brinell Hardness Tester PHB-1 Portable Brinell Tester with 1580 kgf Test Force, 100-650 HBW Range and 0.8 kg Portable Design

The PHB-1 Pin Impact Brinell Hardness Tester applies the Brinell hardness test method and loads the test force by hammer impact, with the force precisely controlled by a shear pin. Accurate test force leads to excellent result consistency.

Test force F = 1580 kgf, diameter of test ball D = 7.26 mm, giving F/D² = 30. Based on the Brinell similarity principle, the test condition is equivalent to the standard condition of a 3,000 kgf, 10 mm test ball bench Brinell tester. Just hit on the side to test the part — low requirements on the shape and size of the test piece.

Unlike Leeb hardness testers, which require conversion of the measured value, the PHB-1 reads Brinell hardness directly. Reliability, repeatability and accuracy are higher than Leeb hardness testers and old-type hammer Brinell testers, and the result is widely accepted against product standards and drawings in international trade.

Only one low-cost shear pin is consumed for each test, so the running cost per measurement is very low.

• Direct HBW reading, no conversion required — results are directly comparable to bench Brinell testers and widely accepted against product standards and drawings in international trade.
• Equivalent to 3000 kgf / 10 mm ball bench test — test force F = 1580 kgf with test ball D = 7.26 mm, F/D² = 30, following the Brinell similarity principle.
• True constant test force — the shear pin breaks at precisely 1580 kgf, giving far better consistency than hammer-force guesswork. No electronics, no battery, no power supply required.
• Test huge and super-huge parts in place — no clamping and no loading into a laboratory. Apply force from any angle: top, bottom or side of the workpiece.
• Lightweight and portable at only 0.8 kg net weight — single-person operation on shop floors, construction sites and in the field.
• Dual indenter covers 100–650 HBW — Φ7.26 mm steel sphere indenter for 100–350 HBW, Φ4 mm carbide sphere indenter for 350–650 HBW.
• Low surface preparation requirement — light oxidation or rough-machined surfaces can be tested directly. Only one low-cost shear pin is consumed per test, and the indentation is retained for re-check.
