Air Void Analyzer

The Air Void Analyzer(AVA) is used to measure the air-void parameters.

Auto Shrink

The Auto-Shrink system measures the unrestrained autogenous shrinkage of a specimen of cement paste or mortar cured under sealed conditions


Be4Cast is an advanced software package for simulating temperature evolution and stress development in concrete structures during early-ages

Bond Test/ Pull-Off test

Bond Test is a pull-off test which can be used to evaluate the in-place bond strength between a repair overlay and the substrate, tensile strength of concrete/ other materials, strength of surface concrete, etc.

CMD(Crack Monitoring Device)

The CMD system is used to monitor the opening and closing of a surface crack as well as relative lateral movement between the two sides of the crack as a function of time.

Coma Meter

The COMA-Meter (COncrete MAturity-Meter) is used to measure the maturity of newly cast Concrete at a depth of 80 mm.


CORECASE is a portable light weight coring rig for quickly obtaining drilled cores that are accurate in diameter, have straight sides, and are perpendicular to the surface.


CorroEye is used to monitor the corrosion rate of steel reinforcement in critical areas of a reinforced concrete element or structure by means of a post-installed sensor.


CorroWatch is a monitoring system for early warning of the onset reinforcement corrosion.

Cut & Pull Out Test

CAPO (Cut and Pull Out) Test determines the in-situ compressive strength of concrete in the pre-existing structures without the need of any pre-planning.

DOCter- Impact Echo Test System

Impulse Echo tests involve introduction of a stress pulse by a mechanical impact and studying the frequency response of the reflected waves. The dominant frequency in the frequency response is used to compute either the depth of the member or the possible depth of the flaw.


Corrosion rate and Half-Cell potential of reinforcement; electrical resistance of concrete

ICAR Rheometer

ICAR Rheometer is a rugged, portable instrument for measuring the fundamental flow (rheological) properties of fresh concrete. The system was developed at the International Center for Aggregate Research (ICAR).

LOK Test

LOK Test determines the early age strength of concrete by using pre-installed inserts.


The Merlin is one of the newest developments by Germann Instruments. It is used to measure the bulk electrical conductivity, or its inverse, the bulk electrical resistivity, of saturated 100 by 200 mm concrete cylinders or cores. The test is simple to perform and a test result is obtained within two seconds.

Mini Great Dane

The Mini Great Dane is used to measure the half-cell potential of uncoated reinforcing steel in concrete (in accordance with ASTM C876) and to measure the electrical resistance of the cover concrete.


The MIRA Tomographer is a state-of-the-art instrument for creating a three-dimensional (3-D) representation (tomogram) of internal defects that may be present in a concrete element. MIRA is based on the ultrasonic pitch-catch method and uses an antenna composed of an array of dry point contact (DPC) transducers, which emit shear waves into the concrete.

Moisture Encounter

Moisture Encounter is used to measure near-surface moisture content in concrete or other Materials.• During condition surveys, e.g. for corrosion investigations, or • To check whether drying measures were adequate prior to applying a coating or an overlay on an existing element or floor.


An adaptor of the appropriate size is threaded to the anchor bolt. A counter pressure assembly is placed on the concrete so that it is centered with the anchor bolt.

PROOVE'it- Rapid Chloride Permeability Test System

The PROOVE'it system is used to evaluate the resistance of concrete to the ingress of chloride ions.


The PUNDIT (Portable Ultrasonic Nondestructive Digital Indicating Tester) is used to measure the propagation speed of a pulse of ultrasonic longitudinal stress waves.

Rapid Alkali Test

The RAT (Rapid Alkali Test) measures the amounts of sodium and potassium ions that may contribute to alkali-silica reaction (ASR), which is harmful to concrete structures.

Rapid Chloride Test and Rapid Chloride Test Water

The RCT and RCTW systems are used to accurately and quickly determine the chloride ion content from powder samples of concrete obtained on-site or in the laboratory.

s'MASH- Impulse Response System

s'MASH impulse response test system is an easy to use method for rapid screening of the integrity of structures.


Surfer is a compact hand-held instrument for measuring the propagation speed of a pulse of ultrasonic longitudinal stress waves.

Water Penetration Test- GWT

The GWT measures the water permeation of water into the test surface under applied pressure.
