Key Advantages
Dual Models Available to Match Your Test Demand
- LQ-QFZ Manual Model: No power needed, low investment cost, simple operation, perfect for small laboratories, on-site random sampling inspection and small-batch workshop detection.
- LQ-QFD Electric Model: Fixed stable rotation speed at 80 r/min, eliminates human operation speed deviation, ensures uniform test force and consistent test results, ideal for mass continuous batch testing in large coating factories.
High Precision 808 Hardened Steel Stylus, Long Service Life
Equipped with industry-standard 808 steel test needle, tip radius only 0.05mm, high hardness and strong wear resistance. It can keep stable test accuracy after thousands of repeated scratch tests. Spare steel needles are supplied in bulk (100 pcs per box) for easy daily replacement to reduce your maintenance cost.
Flexible Adjustable Parameters & Complete Standard Accessories
- Drawing diameter adjustable range: 0~10.5 mm, compatible with various coating thickness test requirements
- Full set standard counterweights: 100g, 200g, 200g, 500g, flexible to match different test loads
- Effective sliding travel: 80 mm; Worktable dimension: 50×120 mm, fits most common metal test panels
- All matching weights and spare needles are delivered together with the machine, no extra purchase needed
Sturdy Integral Cast Metal Frame, Stable Test Performance
Integral blue cast iron main body, anti-deformation and shock-resistant. The sliding worktable comes with locking fixtures, which can firmly clamp test samples to avoid displacement during scratching, effectively guarantee test repeatability.
Standard Compliance, Widely Used in Coating Industry
Fully complies with GB/T 1720 circle drawing paint film adhesion test standard. Widely applicable to detect adhesion performance of liquid paint, powder coating, anti-corrosion coating, decorative finish on aluminum, steel, iron metal substrates. It is essential lab equipment for powder spraying factories, metal surface treatment plants, paint manufacturers and third-party testing laboratories.
