GEODETIC TARGET
TARGETS
& SURVEY MARKER
Targets are extensively used for measurement of deformation during tunnelling and subway construction,
and for monitoring displacement of a bridge, dam, slope or building structure.
Model ERT-10B
Bi-Reflex Target
ERT-10B consists of reflectors on both sides mounted on a universal
joint. The target has a small centre hole to allow precise targeting.
Targets are interchangeable.

SPECIFICATIONS

Measuring range 1 Typically 12 m to 140 m
Material Reflector support is plastic, mounted on
universal joints with reflective foil on both
sides.
Model ERT-10P2
Prism Target
ERT-10P2 consists of a mini prism mounted on a universal joint such
that it can be oriented in any direction as required. The prism is
copper coated.

Optional components for ERT-10B & ERT-10P2
• Adaptor with a plastic reference break-off point.
• Convergence bolt of zinc plated steel constructions, 12 mm
diameter x 170 mm long, with 3/8” pipe thread stud with
protective cap.
Model ERT-20P2-M1
Mini Prism Target
ERT-20P2-M1 mini prism target consists of a prism mounted on a
swivel bracket. The prism is copper coated.

SPECIFICATIONS

Measuring range 1 Typically 0.3 m to 600 m
Material Prism support is plastic, mounted on a
universal joint.
1 Maximum measuring distance is highly dependent on atmospheric
conditions and EDM model used.

SETTLEMENT POINTS
Model EBS-16
Building Settlement Point
EBS-16 building settlement basically consists of a spherical reference
locator with threaded bolt.
Model EPS-12
Pavement Settlement Point
EPS-12 pavement settlement point basically consists of a plastic
tapered disc and a special retaining nail.

Model ESMP-10/ESMP-11
Ground Settlement Point
ESMP-10 comprises of an AISI-304 survey pin having a semi-
spherical top. A red coloured cross mark is provided at its top.
Variations (ESMP-11/ESMP-12) are available with extension rods/
anchors to suit different applications.
