1. It is applicable to IPX7 waterproof grade test of products.
2. The allowable height and water depth of this box are 1.1 meters, and the bottom area is 300 * 300 mm. (Customizable)

3. Double-layer structure of immersion tank:
① The inner layer is formed by high-precision integral sub-arc welding of SUS304 # stainless steel plate to ensure that it will not rust and leak after long use;
② Stiffeners are used in the middle of the two layers to ensure that the inner box does not deform;
③ The outer layer is welded with hairline stainless steel plate, which is wrapped with stainless steel plate. The appearance is free of welding spots, and the overall appearance is beautiful and generous.

4. The water inlet and outlet pipes are installed under the water tank.
5. The observation window is made of 8mm tempered glass, which can clearly observe the test condition of the sample.
6. The stainless steel chassis is equipped with load casters and foot cups, which is convenient for movement and fixation.
7. A stainless steel hook is welded on the top of the inner chamber to facilitate the user to take and place the test sample.

Test conditions of ipx7 Immersion tank Waterproof test Device:

1. The low point of the shell with a height less than 850 mm shall be 1000 mm below the water surface;
2. The high point of the shell with a height equal to or greater than 850 mm shall be 150 mm below the water surface;
3. The test duration is half an hour;

Technical parameters of the Immersion tank Waterproof test Device:

1. External dimension of water tank: about 880 mm long * 880 mm deep * 1520 mm high (including casters);
2. chamber size: about 800 mm long * 800 mm wide * 1200 mm high;
3. High test water depth: 1.2 m;
4. Box material: tempered glass (thickness: 12mm);
5. Water level adjustment method: directly below the valve adjustment;
6. Water level display: stainless steel ruler (precision 1mm), horizontal visual;
7. Frame material: stainless steel square.

Function description of Immersion tank Waterproof test Device:

1. Tempered glass: fully transparent, can observe the test condition of the test sample; It is durable and watertight for long time use.
2. Stainless steel frame: fix and support glass water tank, firm and reliable.
3. Water level gauge: display the actual water level, and the small scale unit is mm.
4. Water inlet and outlet valve: there are two external water valve switches on the front of the base, one inlet valve and one drain valve.
5. Water inlet and outlet: the water inlet and outlet are under the glass water tank, hidden under the stainless steel base, with water inlet and outlet pipe joints.
6. Castor: easy to move the water tank; The castor has a brake, which can easily fix the water tank.
7. Foot cup: fix and support glass water tank, firm and reliable. Prevent slipping and danger.

How to change the water after the immersion test of the ipx7 Immersion tank Waterproof test Device?

The user observes the ipx7 Immersion tank Waterproof test Device. If the water quality in the box is turbid or there is a large amount of scaling in the chamber, the water should be changed in time.
1 Connect the drain pipe, and connect the other end to the ditch or floor drain and other places conducive to drainage.
2 Unscrew the drain valve at the bottom of the water tank and start to drain.
3 Lift the sample basket and move it to the side.
4 Clean the dirt on the inner wall with a long-handle cleaning brush; After cleaning, flush with water (the drain valve remains open).
5 After cleaning, add water again.

How can the test of the ipx7 Immersion tank Waterproof test Device be judged as qualified?

Immerse the electronic product in the IPX7 Immersion tank Waterproof test Device with a water depth of 1-1.2 meters for 30 minutes, and the electronic product is qualified if it has no harmful effects.

Test steps of ipx7 Immersion tank Waterproof test Device:

1. Add water to the standard water level (pay attention not to completely fill the water tank, otherwise the water will overflow when placing the sample);
2. Clean the sample to avoid bringing impurities into the water;

3. Put the sample into the basket, and then press and hold the lowering key. When the basket is lowered to the proper position, release the key to stop the lowering;
Prompt: Release the key immediately after the sample basket reaches the bottom, and do not hold it down, otherwise the steel rope will be loosened too much, which is easy to cause jamming.

4. Time for 30min (during this period, users can observe the test in the water tank around); After the test time is up, you can take out the sample by yourself and observe the test results;
5. End of test; If the water quality is polluted, turbid or not used for a long time, the water tank can be drained.

JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization for the products such as electrical & electronic products, LED luminaires as well as in the relevant quality control department for the waterproof detection of the enclosures protection grades.
