HAND PENETROMETER
· Accurate hydraulic reading dial, equipped with
drag pointer
· Ideal for agronomists and contractors
· Can be operated with full body weight
· Comes with all rods and cones, 1 - 5 cm
2
EIJ 06.01.SA
SURFACE PENETROMETER
· 50 N (5 kgf) compression spring and robust
steel design
· Determine the penetration resistance of top
layers (measuring depth 5mm) and of samples
in the field or in laboratory
· Composed of a housing, spring, flat-tipped
measuring pin, slip ring and a scale
· Calibrated for easy and immediate penetration
resistance readings
EIJ 06.03
SOIL PENETROLOGGER
· Measures the resistance for penetration of
soil prior to paving
· Cones are from 1 cm to 5 cm to fit soils
from hard to very soft
· Datalogger holds large amount of data
divided in projects and plots
· Large LCD display graphically shows depth,
used force, penetration speed, project
name and plot number
· Depth is determined by sonar, force by a
motionless sensor, up to 80 cm
· Can be connected to a field or office printer
or laptop computer, data can be further
processed on a PC
· Comes calibrated and ready for use
· 110 V charger, manual, case and optional
field printer
EIJ 06.15
CONDUCTIVITY METER
· Follows soil moisture behaviour
· Records conductivity and temperature
· Large memory, data can be sent with modem
· In situ field uploading possible with the IR
EIJ 11.41.11.SA
DOUBLE RING
INFILTROMETER
· A straightforward instrument to determine
infiltration capacity of top soils for irrigation,
drainage and erosion control studies
· Readings are done in the central ring
· Double ring system prevents radial flow of
water under the central ring
· Includes
(3) sets of stainless steel rings

EIJ 09.04
BAILER STAINLESS STEEL
· Simple, light and compact
· High grade material prevents contamination of
the sample
· Less volatilization, turbulence and oxidation
by emptying of the sampler using an emptying
device
· Easy to clean with diluted acids, lye, alcohols
or detergents (sterilization is also possible)
EIJ 12.04
LIQUID LAYER SAMPLER
· Translucent teflon and stainless steel sampler
suitable for indication of layers, measuring
thickness of floating layer and sampling
of drums, tanks on lorries, gully holes and
shallow oil separators
· Depth-specific samples can be taken
· Silicone piston allows sampling of thicker,
viscous fluids and sludge layers, all while
maintaining thickness of layers
