New Clegg Impact Tester / Clegg Decelerometer 0.5 kg with Hard Case for Golf Greens & Bunker Sand
Click here for model for Sports Turf and Athletic Fields
The 0.5 kg Clegg Impact Tester is a
professional instrument used to determine hardness on all types of areas - Readings
in Gravities (Gmax), CIT's and F355 Equivalent
Now with the ability to connect a FieldScout TDR350 Moisture Sensor for natural grass or a Mascaro Infill and Cleat Depth Tester for synthetic turf.
The Clegg Impact tester has a wireless bluetooth sending unit and GPS enabled tablet, data logging and mapping. The NEW PNCLEGG-S-2.25-A- Clegg
Impact Tester 2.25 kg model reads out from 0 to 150 Gravities, 0 to 15
CIT's or 0 to 218 - F355 GMax equivalent readings and has a better accuracy range (+/- 1% or 1.5 G Accuracy) as compared to the 0-500 Gravity
unit (+/- 1% or 5 G Accuracy) for testing soft surfaces like golf greens. Also, the 0.5 kg size will not damage the putting surface.
The 0.5 kg Clegg Impact Tester unit is a professional instrument to determine hardness specifically on Golf Greens, Golf Green approaches and bunker sand. These reading will ensure consistant playablity and uniformity from green to green.
Instruction Manual and App comes with conversion formula to
convert readings to F355 equivalent readings. Note the 150 g maximum reading on
this unit is sufficient for maximum impact readings in the ASTM F355 range after
using the conversion formula included in the Turf-Tec Instruction Manual. 200 g's on F355 Impact Tester = 135 g's on Clegg Impact Tester.
The principle behind the Clegg Impact Soil Tester, also called the Clegg
Hammer and Clegg Decelerometer, is to obtain a measurement of the
deceleration of a free falling mass (Hammer) from a set height onto a
surface under test to determine its hardness. The impact of the Hammer produces
an electrical pulse, which is converted and displayed on the GPS enabled tablet in
units of gravities "G-max", tens of gravities "CIT", or F355 Equivalent units. Reference ASTM test
methods ASTM 1936, ASTM F355, D5874 and F1702.
The standard test protocol for sports field testing is to drop the hammer
one consecutive time on the test area result. The Clegg offers the convenience of
rapidly scanning compaction variation over large areas.

Simple and quick test procedure
- The 0.5 kg Clegg test procedure is very rapid and can easily be performed by site
personnel with minimal training. Each test can be completed in less than
30 seconds and the results are immediate.
- Select a fairly level surface.
- Set the guide tube into position. Secure by placing a foot on the
tube's base flange and steady with the lower leg and knee.
- The tablet app is placed in the test mode.
- The Hammer is raised to the drop height designated by the top stop.
- The level is centered.
- The Hammer is released allowing it to fall freely.
- The Gravities value (Gmax), CIT value or F355 equivalent reading is displayed and is instantly saved, along with the GPS coordinates, into the Clegg app.
- Move to the next test site and repeat the test procedure.
