LA-316 Concrete Air Content Tester

1、 Purpose:

The LA-316 concrete air content tester is mainly suitable for testing the properties of ordinary concrete mixtures according to GB/T50080-2002, as well as for concrete experiments in admixtures, hydraulic engineering, highways, railways, and construction projects. This instrument is composed of a cylindrical container with a flange, a lid, and an air pump pressure gauge and valve according to BOYLE's law Due to the equilibrium of pressure within the two chambers, changes in atmospheric pressure have no impact on the experimental results This system can also be used for unit weight measurement of fresh concrete and aggregates

2. Characteristics:

1、 Speed suitability test - no need to draw a curve, directly read the gas content measurement value

2、 Suitable speed for pressing and clamping system

3、 Lightweight, with a built-in manual pump for easy portability

4、 Not affected by changes in atmospheric pressure

5、 Practical and compact in structure, it is most suitable for high-frequency use on construction sites

3. Technical indicators:

1、 Capacity: 7 liters

2. Range of air content; 0-10%

3. Accuracy: 0.1% within 6% of the range

4. 0.2% between 6% and -10% of the range
