This Operating Manual explains the operation of five air entrainment meters, all with identical functions. If a list of different technical data or parameters is given, then they shall apply to the three models as follows: 1. 0.5 litre; TESTING article no. 1.0334 2. 0.75 litre; TESTING article no. 1.0337 3. 1 litre;...

The system measures the air content of the fresh mortar or fresh concrete in accordance with a pressure-equalization process.

Then slightly moisten the inner surfaces of the test pot with a moistened cloth or sponge.

For the 0.5; 0.75-litre and 1-litre TESTING air entrainment meter: Adjust by making one complete turn of the hooks of the clamps. For the 5-litre,7-litre and 8-litre TESTING air entrainment meters: In making precision adjustment of the quick-release latches, one complete turn of the clamp hooks can often be too much.

13. Now note the apparent air entrainment reading (A1) of the fresh mortar or fresh cement in percent. 14. After the testing is finished, slowly open both of the two ball shut-off valves. This will allow the pressure to be released from the test pot.

For practical reasons, it is not necessary to apply the aggregate correction factor when you use normal and dense aggregate (G = 0).
This additional air volume will compensate for the loss of air volume during testing of the air entrainment (this loss of air volume is due to the technical design of the device). The initial pressure that applies to each device has already been set and marked by the red marking pointer during factory testing, before each air entrainment meter is shipped to its users.
At the same time, tap with your finger gently against the dial of the pressure gauge until the pointer comes to rest. Results of testing for the initial pressure The following three test results are possible: If the black pressure-gauge pointer moves to 0 %, then the position of the red marking pointer is correct (for more details, please see Section 4.3).
• To calibrate the 1-litre TESTING air entrainment meter, you will need to take 100 g of water as test volume from the water-filled meter. This corresponds to 10 % of the total water content of the test pot (total filling = 1000 g, which is 1 litre = 1000 cm³...
8 litre; model: TESTING 2.0334 • To calibrate the 5-litre TESTING air entrainment meter, you will need to take 250 g of water as test volume from the water-filled meter. This corresponds to 5 % of the total water content of the test pot (total filling = 5000 g of water, which is 5 litres =5000 cm³).

With respect to the testing procedure, the relevant standards, directives, regulations, and instructions of the supervisor in charge will always apply.
Disposal and recycling These air entrainment meters be disposed of as special waste. The company TESTING Bluhm & Feuerherdt GmbH can also dispose of these meters, provided that they are transported to TESTING without cost to TESTING. If these air entrainment meters are disposed of by the owner or user, they must be scrapped in accordance with the pertinent legal regulations and the applicable regulations published by the professional associations involved.
