This instrument is used to determine paint film hardness through indentation testing, with hardness expressed as the reciprocal function of indentation length (indentation resistance). Indentation device weight 1kg±5g, indentation load 500±5g, reading accuracy 0.1mm. Available in different load specifications and different indentation device weights to suit various coating hardness testing needs in paints, automotive, furniture and other industries.

This instrument is used to determine the hardness of paint, coating and varnish films by measuring the damping time (seconds) of pendulum swing attenuation on the coating surface. Available in Konig pendulum (weight 200g, length 500mm, steel ball diameter 5mm, period 1.4s) and Persoz pendulum specifications. Equipped with automatic counting device, initial angle 6°, final angle 3°, timing range 999.9s. Common equipment for coating hardness testing in paints, automotive, furniture and other industries.

This sag resistance tester is used to determine the sagging performance of paints during application and drying on vertical surfaces. It rapidly evaluates sagging tendency through multi-groove film thickness gradients (50~675μm, 25μm gradient). Suitable for paint formulation adjustment and optimal application thickness determination, not applicable to varnishes and powder coatings. Available in different film thickness ranges and different gradient specifications to suit various paint production and application quality control needs.

This IWATA cup (viscometer cup) is used for rapid viscosity determination of paints, inks, coatings and other liquids. Inner orifice φ3.81±0.05mm, inner vertical height 43±0.1mm, operating temperature 0~50℃. Viscosity is evaluated by measuring the time (seconds) for liquid to completely flow out of the cup. Compact, lightweight and easy to operate, suitable for production line and laboratory rapid testing. Available in different orifice sizes and different cup capacities to suit various paint and ink industry viscosity testing needs.
