The UTEST Semi-Automatic (Motorized) range of single testing chamber and double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples. These compression and flexure testers are the results of continuous applications and research studies to upgrade the machines with the latest technologies and conform with current standards EN 196-1, 459-2, 1015-11, 13454-2; ASTM C 109, C348, C349 and BS 3892-1, 4551-1 in terms of its technical properties taking into account client requirements by using suitable accessories. These testers also meet the requirements of CE norms for safety and health of the operator.

The UTEST Semi-Automatic cement compression and flexure testing machines allow operators who have minimal experience to perform the tests.

The UTEST Semi-Automatic cement compression and flexure testing machines consist of a very rigid two column single or double chamber frame and UTC-4820SLP hydraulic powerpack with LPI  Battery Operated Digital Readout Unit.

Compression and flexure jigs, distance pieces, and also removable transparent front-rear safety doors (should be factory installed) should be ordered separately.



Power Pack

The UTC-4820 Motorized (Semi-Automatic) Power Pack, controlled by a pressure rate control valve, is designed to supply the required oil to the load frames for loading. The power pack can load different frames with required pace rates. A rapid approach pump is supplied as standard. The power pack is equipped with a safety valve (maximum pressure valve) to avoid machine overloading.

The dual stage pump is formed by two groups, one is low pressure gear pump and second high pressure radial piston pump.

On the dual stage pump, high delivery low pressure gear pump is used for rapid approach, while low delivery high pressure durable variable output pump is used for test execution. Rapid approach property of the machine shortens the time interval from the piston starts moving until the upper platen touches to the specimen and helps to save a great amount of time in case of numerous specimens are going to be tested.

The motor which drives the dual pump is an AC motor and 0.55 kW.

A distribution block is used to control the oil flow direction supplied by the dual stage pump and those are are fitted to solenoid valve, safety valve (maximum pressure valve), low pressure gear pump and high pressure radial piston pump

The tank (20 L capacity) includes enough oil to fill the mechanism which pushes the ram during the test. The level and oil temperature can be seen on the indicator fitted to the tank. Hydraulic motor oil number 46, must be used in the tank.


UTC-4920LP_LPI_Battery_Operated_Digital_Readout_Unit (1)

LPI Battery Operated Digital Readout Unit

The LPI Battery Operated Digital Readout Unit (UTC-4920LP)  has been designed to use with load cells or pressure transducers on different material test applications.


The unit is operates with DC voltage source of -1,5 to 1,5 volts.

  •  Real time numeric display of load and load rate
  •  1 channel with two different calibration table (by changing the sensor belong to other frame, the unit can be control for second test frame)
  •  Peak hold property
  •  Multi-point calibration
  •  Can operate with 2 x AA batteries
  •  Easy preload zeroing
  •  Serial port for PC or printer
  •  8 keys keyboard


Main Features

  • Class A (ASTM) starting from with the 1 % of the 250 kN and 15 kN capacity Multi-point calibration
  • Multi-point calibration
  • 2 channels  for load-cell or pressure transducer  with two different calibration table (LPI Battery Operated Digital Readout Unit (UTC-4920LP)
  • Real time numeric display of load and load pressure
  • Peak hold property
  • RS232  Serial port for PC or thermal or dot matrix printer
  • Free of charge Utest software for compression/flexture testing machines(USOFT-4820.SLP)  for compression, flexture, splitting tensile strength tests of construction materials such as concrete, cement, brick/masonary units


Safety Features

  • Maximum pressure valves to avoid machine overloading
  • Piston travel limit switch
  • Removable transparent front-rear safety doors (Should be factory installed and ordered separately)


Utest Software for Semi-Automatic Cement Compression/Flexure Tests (USOFT-3722.SLP) 

USOFT-3722.SLP Test Software is improved for semi-automatic cement compression and flexural testing machineswith LPI Battery Operated Digital Readout Unit  durring the test to collect and record data and to prepare the report containing the results obtained.Before the test, a PC which the Utest software is installed is connected to RS232 port of LPI reading unit, the data obtained in the test  can be monitored and recorded in real time. The advanced functions for data base management provide an easy navigation of all saved data. Test report including the test results and user defined test information (names and the Company details, test type, specimen type, user info and other knowledge required) can be print out.

The Maximum horizontal clearance for placing the sample is limited by the border of the platens. Sample must be placed such that its ends will not overlap the ends of platens and it must be centered perfectly. The suitable vertical clearance for the specimen can be adjusted using the distance pieces.
