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.

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.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.
