Clegg Impact Hammer Soil Tester Type With GPS for Winter Sports, Cricket and Equestrian – 2.25 kg

The Clegg Impact Hammer with GPS can be used to measure the hardness or shock absorption properties of many sports surfaces. The integral GPS is a useful feature for ensuring the spatial consistency of pitches and other surfaces, identifying problem areas and taking repeated measurements over time.

The Clegg Impact Hammer with GPS is particularly suitable for winter sports pitches, cricket pitches and equestrian surfaces.

Uses

A Clegg Impact Hammer assists with the preparation of quality and consistent playing surfaces in many sports. It can be used to aid decisions relating to playing surface quality and safety as well as turfgrass health. The Clegg Impact Hammer soil tester is simple to use and produces straightforward and unbiased results.

 

In cricket the Clegg Impact Hammer soil test is a good predictor of both bounce and pace. This makes it a useful addition for an unbiased determination of playing surface quality.

Winter sports which have a risk of injury due to hard ground can similarly take advantage of the unbiased results provided by the Clegg Impact Hammer to aid decisions relating to safety. The results have been demonstrated to correlate closely with head injury severity indexes. In addition, the test can be used to indicate shock absorption and ball rebound qualities of the playing surface.

+ The Clegg Impact Hammer can also be used on other types of surface (e.g. tennis courts, bowling green, equestrian surfaces etc.)

*Deceleration due to gravity.

 

The Clegg Impact Hammer can also be used to assess surface consistency throughout the year and across different areas of a surface. This requires multiple measurements to be made across the surface of the pitch to calculate the degree of variation between measurements. The Clegg Impact Hammer with fitted GPS will enable measurements to be linked to location enabling greater ability to identify areas which require treatment and ensuring that assessments of surface hardness over time are taken in the same locations to increase the reproducibility and robustness of results.

Operation

Operating Principle:- The Tester consists of a 2.25 kg compaction hammer operating within a vertical guide tube. The Hammer falls through the tube when released and strikes the surface under test, decelerating at a rate determined by the stiffness of the material within the region of impact. The readout registers the hardness values in units of Gravities (G). Harder surfaces will have a higher G reading.

Design:- The Clegg Impact Hammer Soil Tester is a very rugged design suitable for prolonged use in damp, dirty and harsh site environments. The CIST/883 readout unit is made from high strength alloy that has been proven to last for decades. The CIST/883 Clegg Impact Soil Tester is a compact and reliable instrument. A Transit & Storage Case is included. The Clegg Impact Hammer with GPS also features automatic GPS measurements to provide latitude and longitude location information.

Test Procedure:- Carrying out a test is quick and straightforward. The guide tube is placed in position vertically on the surface to be tested. The digital readout is located on the guide tube during testing allowing easy use as there is no need to hold the readout in the hand. The hammer is raised to the desired height and then allowed to fall freely. This procedure is repeated three times. The reading achieved on the third drop being recorded as the measurement value. The test data is recorded in the instrument and it is downloadable to a computer wirelessly by Bluetooth.
