Two complete kits — ready to test out of the case.

Both kits are supplied calibrated, certified and ready to use in a wheeled flight case.

Buying your first Pendulum? We recommend the Deluxe kit.
It includes the aluminium sample holder and float glass that are essential for compliant on-site testing from day one — items most new users don't already own. If you're an existing user adding a second tester, the Standard kit is all you'll need.

How it works

The pendulum principle.

The Pendulum measures the frictional resistance between a rubber slider on the end of a swinging arm and the surface under test — giving flooring and highway engineers a routine way to check slip and skid resistance, wet or dry.

The device is placed on the surface, levelled, and the height of the arm's suspension is set against a setting gauge. The arm is released from horizontal and swings down until the slider contacts the surface. As the slider travels a fixed distance, the arm slows and a pointer marks the highest point of the arc.

The pointer is read on a scale graduated 0 to 150 — the Pendulum Test Value (PTV), indicating resistance to slipping and skidding. All Pendulums require annual calibration to remain compliant.
