Thermographic result of a pillar .
Tem peratura
The thermographic test can display a thermal images of the materials
present in a investigated element, using the principle of different
natural thermal emission in the infrared spectral band. They are
conducted with the use of a camera, that measures the temperature of
bodies at a distance, without physical contact between measuring
equipment and the surface investigated. It depends on each material
continuously emits energy in form of radiation and elettromagnetic
waves, in proportion to its surface temperature.
They can be used to locate hidden structures (pre-existing forms,
structural changes, abnormalities construction, presence of cavities),
and degradation (pad humidity, heat loss).

ENDOSCOPY
Modular endoscopy (boroscopy) PCE-E 122
with eyepiece for eyeglass attachment of L = 100 cm and 60 ° field of view,
front lens for vision with adjustable light intensity.
Execution of an endoscpy in a wooden beam
The endoscope is a diagnostic investigation microinvasive
instruments, useful to watch inside an investigated element, through a
hole diameter not exceeding 12 mm. This instrument consists of a
monocle zoom and focus, connected to a digital camera connected to
a side view lens with 90 ° or 60 ° front. The endoscope is thus able to
observe a structure inside and documented the conditions of
conservation through photos of the need to make a hole but does not
make it suitable to make an extensive campaign.

PACOMETER COVERMASTER CM9
Precision digital detector magnetometric with microprocessor
with IP54 protection and complies with international BS1881: 204 and DGZfP: B2
Execution of a pacometer test
The pacometer is used to locate the presence of metallic elements,
mainly associated with reinforcement of concrete structures
reinforced concrete, defining position geometric diameter of sections
of bars and brackets and thickness of concrete cover. It is also used to
locate metallic elements in general (in chains and metal plates, pipes,
plants, etc.).

HAMMER SCHMIDT MODEL NR
Hammer for hardened normal concrete,
with automatic device for recording on the diagram of values of impact.
Energy Impact 2207 N / m. Calibration Anvil Model NR
Execution of a sclerometric test
The hammer is a mechanical instrument that with a impact body hits
the material under investigation with an energy defined and rebounds
with a speed, that depends on the hardness of the same material; the
rebound through a conversion table test determines the compressive
strength of concrete surface. The hammer allows a non-destructive
testing of compressive strength of concrete surface and its decay
behavior, depending on the levels of material degradation.

ULTRASONIC TESTER
Portable digital ultrasonic tester DSP System
for measurement of characteristic values of materials through use of ultrasonic pulses in direct conversation
with microprocessor and frontal LCD display
The method is based on the phenomenon of reflection acoustic wave
undergoes when goes in a material or in an obstacle. If this obstacle
is normal to the direction of propagation of this back to the source
that had generated. The waves are created artificially by special
sources, usually piezoelectric transmitter, the parameter measured is
the time, called the flight time required for ultrasonic signal (or sonic)
to cross the test material. Propagation depends on the density and
elastic properties of the material. Investigations ultrasonic used to
determine the speed of transit of waves inside the concrete and
ultimately provide the E of concrete. These tests are also used to
locate faults in materials such as cracks, holes, porosity
discontinuities in the material investigated. In these circumstances the
waves are reflected and refracted waves.

RESISTOGRAPH
IML RESI F400 Resistograph with standard storage units continues to 22m,
drilling depth 385 mm, Bosch battery drill and 12VES2
Execution of a resistographic test
The resistograph (wood penetrometer) is a micro-invasive
investigative technique useful for qualitative assessment of the
degradation of wood components. Proof is based on the resistance to
puncture the opposite wood and suspect you can make a diagnosis in
situ areas of internal decay of the material investigated. The puncture
resistance depends mainly on the density of wood and is evaluated by
measuring the energy used by the instrument for the advancement of
the tip of a thin steel thickness of about 3 mm at a constant speed. The
instrumentation consists of a sophisticated drill that, with a sharp
point, taking a combined movement of rotation and advancement.
The tip then penetrates into the wood at constant speed to a maximum
thickness of 40 cm, leaving no significant signs.

PILODY
Mechanical penetrometer Proceq 6J-Forest
with integrated depth gauge and depth of penetration up to 40 mm
interchangeable needle of 5 mm in diameter
Execution of a pilodyn test
The Pilodyn is a dynamic tool for penetrating the cortical portion of
wood and the tests consists in to project a thin metal probe in the
wood and its depth of penetration is function of mechanical strength
characteristic of the investigated wooden element and of the level of
degradation in investigated material point. The tool can evaluate the
surface hardness of the examined wood.

DATALOGGER
Datalogger MAGIANT MagLog USB °C – RH%
Technical Specifications : range of temperature measurement (°C) -2 … +85; range of relative humidity measurement
RH 0 … 100%; precision ± 0,5°C/± 2,00% RH; measurement intervals ranging from 1 sec/24h
Performing measurements in a confined
environment
The dataloggers are tools used for investigations relating to the
monitoring of the microclimate in confined spaces and artworks.
They are automatic data loggers (for temperature and relative
humidity) that store the measurement of one or more parameters,
made at appropriate time intervals determined.
Among the advantages of the datalogger than traditional tape
recorders are surely to be counted: large memory capacity (and so
large autonomy), amplitude of the ranges, small size, ability to
manage the alert thresholds, accuracy of measurements, very low
maintenance, versatility of use, cost management (usually contained).
