Vibration frequency: 1Hz
Vibration frequency: 25 times self stop
Net weight: ≈ 20 kg

Installation and commissioning of cement mortar fluidity tester:

It must be fixed on the base with expansion bolt. The instrument base is made of concrete (or brick concrete foundation), with the bottom size of 400mm × 400mm and height of 690mm. The gasket should be filled between the base and the instrument frame (see Fig. 8. Foundation installation drawing). The table top level can be adjusted by adjusting the height of the washer. After the instrument is installed, the table top of the instrument should be horizontal when measured along two diameter directions at right angles to each other. If the standard value of the flow table (jb01) is set, the difference between the measured value and the standard value of the flow table (W1) should be used.
