Used to determine the strain and deformation characteristics of concrete specimens. It comprises two steel rings for clamping to the specimen, two
gauge length bars, and spherically-seated lever unit. Supplied without dial gauge or strain transducer to be ordered separately (see accessories).

C132-01N COMPRESSOMETER for cubes 200 mm side.
COMPRESSOMETER-EXTENSOMETER Ø 150-160 mm
STANDARD: ASTM C469
To measure both axial deformation and diametrical extension of
cylinder specimens Ø 150×300 mm, 160×320 mm, 6”x 12” under
compression stress, by determining the elastic modulus.
It consists of a central ring for the diametrical extension measure, to
be fixed on the C130N compressometer.
Supplied without dial gauges or linear strain
transducers (two required) to be ordered
separately (see accessories).
EXTENSOMETER Ø 100-112.8 mm
Same as mod. C133 but, connected to
C131N1. It is suitable to test cylinders
from Ø 100×200 to 112.8×220 mm.

Technical details: see p. 549
The Compressometers and the Compressometer/Extensometer connected
to electronic linear transducers (accessory mod. S336-11)
can be used with:
– Matest Servo-Plus Evolution compression machines equipped
with Automatic Elastic Modulus system (mod. C125N) in complete
accordance with ASTM C469, ISO 6784, UNI 6556 Specifications
(see p. 284 )
– Matest Cyber-Plus and Servo-Plus compression machines.
The electric cable of the displacement transducer is “directly”
connected to one of the eight channels available on the digital
unit. Through the suitable Software (accessory mod. C130-05),
the digital unit will automatically elaborate the data, supplying the
load/deformation graphic with certificate printing.
C130-05 SOFTWARE for Elastic Modulus test on Concrete Mortar
specimens and tests according to API 19C and
Automatic data and processing acquisition, load/deformation
graphic and certificate printing with direct management
of the testing machine. The software can be
used only with Cyber and Servo-Plus Evolution systems.
S337-51 CALIBRATION PROCESS of one displacement transducer
S336-11 combined with Cyber or Servo-Plus Matest
The Elastic Modulus test, to fully comply EN, ASTM, ISO, DIN,
UNI, BS Standards, must be carried out with a Servo-Plus Matest
machine equipped with C125N automatic system with pace rate
load and “unload” control.
