DRK0041 Fabric Permeability Tester

Product details

Product Introduction

DRK0041 fabric permeability tester is used for tight fabrics such as canvas and oilcloth苫布Tent clothrainproofDetermination of water resistance of clothing fabrics and other materials.

Instrument standards:

GB19082 Technical Requirements for Disposable Protective Stocks 5.4.1. Water resistance；

GB/T 4744 spinningTextile fabric_Determination of impermeability hydrostatic test；

GB/T 4744 Testing and Evaluation of Waterproof Performance of Textiles, Hydrostatic Pressure Method and Other Standards.

Test Principle:

Under standard atmospheric pressure conditions, the test specimen is subjected to a continuous increase in water pressure on one side until water droplets seep out from the surface of the specimen, and the hydrostatic pressure borne by the specimen is used to represent the waterpenetrateRecord the resistance encountered by the fabric and the pressure at that time.

Instrument Features:

1The whole machine shell is made of metal baking paint, and the operating table and some accessories are made of special aluminum profiles. The fixtures are made of non steel materials

2The panel is made of imported special aluminum material and has metal buttons;

Unpacking of instruments:

When you receive the device, please check if the wooden box has been damaged during transportationCarefully open the packaging box of the equipment and check for any damage to the components. Please report the damage to the carrier or our customer service department.

Debugging:

1. After unpacking the equipment, use a soft dry cotton cloth to wipe away dirt and packaging sawdust from all parts. Place it on a sturdy workbench in the laboratory and connect it to a gas source.

2. Before connecting the power supply, check whether the electrical parts are affected by moisture or other adverse phenomena.

Maintenance and upkeep：

1. The instrument should be placed in a clean and stable foundation.

2. If the instrument is found to be working abnormally, please turn off the power in a timely manner to avoid damaging the components.

3. After installation, the instrument casing should be reliably grounded with a grounding resistance of ≤ 10.

4. After each experiment, the power switch should be turned off and the plug of the instrument should be unplugged from the power outlet.

5. After the experiment, drain the water and wipe it clean.

6. The working pressure of this instrument shall not exceed the range that the sensor can withstand.
