C-1925A Pro Model Ultrasonic Tester

Ultrasonic Testers

Ultrasonic testers are used to determine the presence of faults, voids, cracks, etc. in in-situ or precast concrete as well as for long term monitoring of structures that are subject to environmental conditions.

The testers give data concerning the homogeneity of the concrete by generating pulses of sound into the concrete and measuring the time it takes the sound to travel from the transmitting probe to the receiving probe through the tested material. In addition, it is also possible to have indicative data about the modulus of dynamic elasticity and strength of the concrete.

Geotest has two models, described here. The pro model, C-1925A, may be connected to the Digital Test Hammer, C-1810A.
ASTM C597; EN 12504: part 4; BS 1881 part 203


C-1925A Pro Model Ultrasonic Tester

This high performance ultrasonic tester is equipped with a microprocessor for combined ultrasonic and rebound hammer data acquistion and processing (sonreb method). Utilizing the most modern technologies, it has a 1/4 VGA color touch screen, USB, RS232, RS485, working system Windows CE. The standard unit includes the instrument in its basic configuration (x-scale 400MHz, 64MB Flash Memory, 64MB Ram) in a palmer container; accessories.

Special Features:

  • Measures ultrasonic impulse speed inside material
  • Measures distance between probes
  • Measures time of impusle through tested material
  • Young’s modulus and Poisson's Ratio
  • Calculation of crack depth
  • Zero calibration with depuration of time for impulse to go through probes
  • Calibration of a defined time value
  • Advanced functions for research purposes:
    – Selection of transmission frequency of impulse
    – Selection of impulse amplitude
  • Infinite filing capacity of test dates, graph tracing
  • Capability to use with two exponential probes or one standard and one exponential probes
  • Ability to transform instrument into oscilloscope
  • Ability to connect to PC or printer (via USB)
  • Ability to connect to internet, manage software files
  • Manual and automatic modes
The Pro model comes in a strong anti-shock carrying case that includes 2–55 kHz probes with connecting cables, calibrating cylinder and contact paste, battery pack; external feeder 230V/24V and battery charger.
Dimensions: 15.75x12x7" (400x300x180mm).
Weight: 6.6 lb (3kg)

C-1920A Ultrasonic Tester Economy Model

This model ultrasonic tester has a large sized blue negative display with high resulution, 320 x 240 pixels; Motorola processor S12; extractable memory SD card; USB, RS232 and RS485 ports. Other features are very similar to the C-1925A. It is capable of performing the same tests listed above for the Pro Model (speed, distance, Young's Modulus, etc). Infinite capacity of data acquisiton, processing and filing of test dates up to 100,000 reads on SD card or Compact Flash. May be connected to PC or printer. Includes everything same as C-1925A except battery pack is NiMn 12V 2000m/A per hour.
