Clegg Turf Soil Impact Tester

The 2.25kg Turf Clegg is a Impact Soil Tester designed and manufactured for an easy and straightforward means for measuring the hardness condition of sports surfaces.

This model Clegg hammer provides good prediction of ball bounce for cricket surfaces and football pitches. Also used for equestrian surface checks, the instrument is used to confirm uniform surface characteristics over play areas and horse tracks.

The impact tester provides a quick and accurate method for monitoring variations in strength and for helping to determine the uniformity of an area. An example of its simplest application is to help determine soft spots or hard areas.

Key Features

The CIST/883 display, similiar to the roading units above, registers the hardness values in units of Gravities (Gm). The Gm value is an indication of soil strength.

The Clegg Turf Impact Soil Tester features a durable very rugged design, suitable for prolonged use in dirty and harsh site environments.

The CIST/883 readout unit is made from high strength alloy that has been proven to last for decades. This model runs on 2 x AA batteries, typically giving up to 12 months operation.
