The Turf-Tec Penetrometer is a professional instrument to determine soil compaction and shows the surface compaction of the soil or the hardness / firmness of the surface

• By dropping the calibrated weighted impact shaft from a known height, the blunt penetrating point enters into the soil showing surface hardness on the graduated scale on the top of the unit
• Helps determine problems before they become visually apparent
• Useful in determining when to Aerify an area and also assess an area for potential problems
• The center weighted shaft is simply raised above the soil surface and then the release trigger is pulled, allowing a 0.25 inch blunt penetrating point to enter the soil by gravity
  

  The top of the shaft is etched with a specially designed engineering scale showing the compaction results as follows:

  • "0" indicated no compaction or uncompacted sand
  • "50%" indicates a soil in good tilth with 50% solids and 50% for air
  • "60%" is typical for firmer golf greens
  • "100%" indicates solid compaction with on penetration and no soil air space similar to a cement surface
