HC-7L Concrete Air Content TesterDetailed product description：

HC-7L Concrete Air Content Tester

According to the BOYLE law, the direct reading concrete air content detector is suitable for measuring the air content in concrete mixtures with aggregate particle size not exceeding 40mm and air content not exceeding 10% and slump. It complies with all the regulations of the Ministry of Transport's 94-07-05(JTJ053-94), and this measurement method complies with the GBJ80-85 standard.
Composed of a cylindrical container with a flange, lid, and equipped with an air pump pressure gauge and valve Due to the equilibrium of pressure within the two chambers, changes in atmospheric pressure have no impact on the test results This system can also be used for unit weight measurement of fresh concrete and aggregates
