HQM-I type concrete air tightness testerDetailed product description：

HQM-I type concrete air tightness tester

This instrument is an experimental device for testing the gas permeability coefficient of concrete, and the calculation formula for using this method to test the gas permeability coefficient is theoretically derived The comparative test results with the Cembureau method demonstrate a high linear correlation between the measured data under the same conditions Experimental results have shown that this method has the characteristics of easy operation, good sealing performance, and reliable test data. It is reasonable and reliable to use this method to evaluate the gas permeability of concrete And adopt fully automatic computer control according to national regulations

Test piece size: 185 * 175 * 150, maximum working pressure: 1.2-1.4MPa, measurement accuracy: less than 0.1ml
