TURF-TEC PENETROMETER©
Instructions
The Turf-Tec Penetrometer* is a precision
instrument to determine compaction in the soil
profile. It operates on the simple principle of
gravity. A calibrated known weight is released
and dropped. A specially shaped penetrating
needle enters the soil and its depth of
penetration registers on the scale.
Since the Turf-Tec Penetrometer is activated
by gravity, its scale readings will always be
consistent. It does not have to be adjusted or
need replacement parts.
HOW TO USE THE TURF-
TEC PENETROMETER
INSTRUCTIONS
A) Position the base of the instrument on
the turf.
B) Release the lock handle located at the
top of the outside tube so that the
calibrated weight shaft slides up and down freely.
C) Raise the calibrated rod until it clicks past the release trigger. Lower gently
until it locks in place. The rod will now extend 18 inches from the top of the
tube to “0” on the scale.
D) Press trigger away from tube and hold to release weight rod. Read depth
of penetration on the scale.
E) The Turf-Tec Penetrometer is calibrated from 10 to 0, “10” represents
100% compaction and zero represents no compaction.
The Turf-Tec Penetrometer is an excellent tool to help the turfgrass manager to
better determine the condition of the soil and the needs of the turf.
The calibrations are assumed to be approximations of actual conditions. Wet or
dry soils will obviously alter the results shown on the scale. Best readings of the
scale can be achieved when soils are in the mid range of soil moisture.
