HG-1000Type digital displayConcrete penetration resistance meter

Use the penetration resistance method to determine the setting time of concrete.

The penetration resistance test is achieved by fixing the sample container with a penetration needle and moving it upwards. The electric motor is driven by a planetary reducerThe speed of 2 revolutions per minute is transmitted to the cam, which drives the roller to rise uniformly. Therefore, the lifting sleeve and the sample container placed on the chassis rise uniformly at the same time, achieving penetration motion.

The resistance is measured using a sealed chamber pressure gauge. When the test sample generates resistance to the penetration needle, this force compresses the oil in the sealing chamber through the force measuring rod, and the increase in oil pressure is indicated by the pressure gauge.
