Designed to depth check loosefill playground surfaces (woodchip, bark, pea gravel etc). Provides visually simple depth inspection and topup required.


The NZS5828:2015 standard requires an average minimum depth of 300mm of quality 'LOOSE' filll material for a playground surface. This probe is designed to supoort regular depth and quality checking of the loosefill material. Made from Aluminium bar with a ergonomic soft rubber handle.


Test Procedure

A soft rubber handle allows easy force to be applied to the back of the probe - In a vertical position apply reasonable force, push probe into loosefill surface until a compacted resistance orother material is identified. Then measure the depth and topup required using the RED 50mm intervals on the probe.


Great for anyone inspecting playgrounds, inspectors, facilities maintenance teams, caretakers etc
