LTD-AType electric impermeable meter

Used to determine the impermeability of waterproofing materials such as asphalt waterproofing membranes, polymer waterproofing membranes, modified rubber membranes, etc. under high pressure.

All indicators of the instrument comply with GB/T 328.10-2007 "Test Methods for Building Water Release Membrane Part 10: Asphalt Polymer Waterproof Membrane"

The relevant provisions of 5.2 in the standard of permeability. Can be used by relevant production, construction, and research departments to determine the impermeability of waterproof materials, that is, the product's resistance to water accumulation

Or a limited surface can withstand water pressure.

Main technical parameters:

1. Test pressure range: (0-1) MPa

2. Pressure gauge working level: 1.5 level

3. Working mode: automatic constant pressure or manual constant pressure

4. Power supply voltage: 220V 50Hz

5. Three samples can be made for each experiment

6. Time setting: freely set between 1s and 99h

7. Dimensions: 700mm × 380mm × 680mm

Electric impermeable meterusage method:

1. Make the material to be tested into three prototype samples with a diameter of 150mm for later use.

When in use, rotate the handle to release and remove the pressure rings of the three permeable discs.

3. Slowly pour distilled water or clean fresh water at 20 ± 5 ℃ into three permeable plates. When the overflow is approaching, place the circular samples on the permeable plates respectively, and then press the empty tablets on top with the pressure plates.

4. Adjust the pressure gauge to the specified pressure value of the material and connect the power supply. Time setting: Set according to material requirements. Then press the start button, and the instrument will start working. When the set time is reached, the machine will automatically sound an alarm.

5. Cut off the power and turn off the switch.

6. After the experiment is completed, open the drain valve, discharge the pressure and water, unscrew the screws, remove the test piece, and clean the instrument.
