| General Information |
|
The instrument UK1401 is designed
for time and velocity measurements of longitudinal ultrasonic waves in
solid materials. It is possible to evaluate the strength
and quality of materials and structures. The strength estimation is
based on correlation between the ultrasonic wave velocity in material
and its physico-mechanical properties and physical conditions. |
|
|
|
The tester UK1401 is an
electronic unit with LCD screen and two built-in ultrasonic probes with
two conical shape protectors. The probes are firmly fixed on the lateral
side of the instrument at the distance (base) of 120 or 150 |

Areas of Application |
|
• |
Concrete strength evaluation based on velocity in accordance
GOST 17624-87 "Concrete. Ultrasonic method of strength
evaluation"; |
|
• |
Estimation of the carrying capacity of concrete pillars and
supports based on relation of propagation velocities in
longitudinal and transverse directions; |
|
• |
Detection of near surface defects in concrete structures by
abnormal decrease of ultrasound velocity (time increase); |
|
• |
Evaluation of degradation and homogeneity of rocks, the
degree of anisotropy and texture of composite material; |
|
• |
Estimation of materials elastic properties similarity and
difference or one material specimen from each other.
Estimation of a material age under condition of its
properties changes from time. |
