B2030 Mortar Air Content Tester

1、 Purpose: The B2030 mortar air content tester is a newly produced mortar air content testing instrument based on the JGJ/T70-2009 new standard specification. This instrument is used to directly measure the air content of mortar, which is convenient, fast, and practical

2. Technical parameters:

Volume: 1L;

Range: 0-50%;

Accuracy: ± 0.1%Size: 200mm (diameter) * 320mmWeight: 4kg

3. Operation process:

1)Weigh the empty bowl and record the weight

2) Place the sealing ring onto the bowl, and then hang the clamping ring onto the rim of the bowl

3)Fill the bowl with mortar and then shake/compact it

4) Remove the sealing ring and use a large iron hammer to push the mortar beyond the edge of the bowl

5) Weigh the weight when the bowl is full, then subtract the recorded weight of the empty bowl to calculate the density of the bulk cargoNow clean the edge of the bowl with a clean cloth

6) Place the upper part onto a clean bowl and tighten the clamps around itOpen the stop valve and raise the control rod. Then use a washing bottle to inject water into the stop valve until the water overflows from the stop valve without any bubbles

8) Turn on the left semi-circular handle to turn on the air pump until the pointer of the pressure gauge points to the position 3 below% AIR. Now slowly turn the screw of the exhaust valve to the left until the pointer of the pressure gauge accurately points to the "position 3 below% AIR". If you point to this position, please turn the screw clockwise to close the exhaust valve. The position 3 below% AIR, which is the initial pressure point, has the same effect as the air content in concrete

9) Close the stop valve

10) Start detecting when the pointer returns to zero. Press the joystick for about 20 seconds until the pointer of the pressure gauge stops moving

Read the percentage of gas content directly on the pressure gaugeSlowly open the stop valve. Then turn the screw to the left and release the excess pressureOpen the upper part, empty the bowl, clean it thoroughly, and wipe all the components dry
