An air permeability test can be done by any one of Qualitest's Blaine test apparatus. We have several options to choose from included an automatic air permeability test apparatus, a manual air permeability test apparatus, a PC-controlled air permeability test apparatus. The Blaine air permeability tester is mainly used to measure the fineness of the cement, which in turn can be an indication of speed of setting and rate of strength development. The testing principle is based on the permeability of air through a sample under certain conditions. This is the ideal testing instrument for cement and concrete testing. We offer variety of Blaine systems fitting the needs of the industry.
QualiPerm I manual air permeability tester is able to perform the Blaine test with a traditional design. This Blaine tester has a manual aspirator to apply the air pressure for test. Qualitest offers this air permeability test apparatus as an alternative to automatic and PC-controlled. It is competitively priced as well as offering the tried and true classical design of a Blaine tester.
The manual operation is has proven to be an effective means to carry out the tests. Moreover, the small footprint means that the machine will be the perfect addition to any facility.
The automatic Blaine air permeability test apparatus QualiPerm II offered by Qualitest has a built-in pump that replaces the aspirator (bulb). The entire test can be run semi-automatically with a greater degree of freedom for the operator than the manual Blaine test apparatus. The automatic time registration is both precise and convenient.
This automatic Blaine QualiPerm II performs Blaine tests according to EN 196, DIN 1164, BS 4550, and ASTM C 204. These international standards ensure that the Blaine tester can perform to the most stringent standards.
Part of the maintenance of a Blaine tester requires routine calibrations; official calibration and other consumables can be purchased as accessories for this automatic Blaine tester when they are required. The built-in pump replaces the aspirator in this new design. The entire test can be run semi-automatically with a greater degree of freedom for the operator than the manual Blaine test apparatus. The automatic time registration is both precise and convenient. The unit runs at 230V/50Hz.
Operation and software of the QualiPerm III is similar to the other PC-operated units. The design of the main unit is unique in that the footprint is much smaller than those units and the measuring cell is fully encased in the metal housing. The sleek design allows for the testing unit to be placed conveniently on any atop any bench within your facility. The main unit is housed completely in metal. The load cell is also well-protected.
Electronic Blaine Apparatus, Dyckerhoff system, QualiPerm IV semi automatic device with pump and time registration for the rapid determination of specimen characteristics. Measuring cell dia.41 mm, volume of measuring cell approx. 73cm3; 230 V / 50 Hz.
QualiPerm V Blaine test apparatus is the next generation of testing apparatus; being fully automated. The test procedure and evaluation is run without the supervision of an operator and is automatic. This system comes complete with software. The measuring cell has a diameter of 41 mm and its volume is approximately 73cm3. The machine runs on at 230 V / 50 Hz. Also available is a system with two-cells giving the ability to measure two points.
The difference between the two air permeability tester in the series (QualiPerm V and QualiPerm VI) is the number of load cells available with which to perform the Blaine test. The QualiPerm V is a PC-controlled Blaine tester model that sports one load. The QualiPerm VI PC-controlled Blaine tester is the model that has two load cells. Both models perform tests that are monitored and recorded by the computer that is included.
