I. Product Introduction

This instrument Automatic Sealing Concrete Impermeability Tester adopts pure imported chips, Win7 operating system, and is centered on a computer with an integrated circuit high-precision control system. The software and hardware adopt multiple anti-interference measures, and the on-site working parameters are stored in real time. It features high control accuracy, no data loss upon power failure, and high reliability. It realizes the characteristics of systematization, intelligence, automation, and humanization of the equipment, and comprehensively leads similar products in the market. It complies with the requirements of standards such as GB/T50081-2008 (Standard for Test Methods of Long-Term Performance and Durability of Ordinary Concrete), JG/T249-2009, T0528-94, and GBJ81-85.
II. Product Features
Six groups of specimens work simultaneously each time (the levels are based on the host machine), completely independently of each other. There are six independent water pumps corresponding to each level.
2. The machine body adopts a bookshelf rear-mounted design with a linked rotating transmission. There are no columns on both sides of the mold for testing, providing a large space between specimens and making it more convenient to install and remove specimens. It is suitable for customers in both large and small laboratory environments.
3. The mold testing adopts the latest seamless steel pipe welding technology. The appearance has undergone heat treatment and galvanization, which is not only aesthetically pleasing but also highly corrosion-resistant. It will not cause damage to the machine itself due to moisture, making it safer and more durable.
4. The airbags are made of imported high-quality Neoprene rubber through die-casting. Neoprene rubber contains over 95% pure natural rubber. The rubber thickness reaches 6 millimeters, providing better pressure resistance and wear resistance. The air pressure is generated by a precise high-pressure pump, which is greater than the water pressure, making it safer and more reliable.
5. Safety in use: The pneumatic connecting rod is mechanically locked. In case of power failure during mold testing, it will automatically stop at the current position and will not drop, ensuring a safe and reliable protection function.
6. By using individual sealed rubber sleeves for separate gas and water supply, 36 test blocks can be made on 6 layers, which improves efficiency, reduces costs and saves space.
7. The GD120F type Fuma universal industrial load wheels are adopted, which are durable, smooth and convenient for movement.

IV. Operating Instructions:
Select the layer you need to operate on, click the letter of that layer, enter the password [1], click [Confirm], and then you will enter the operation page.
2. Unlock the [Safety Lock], click [Rise], and after it stops, place the test piece inside.
3. Click [Exhaust], then click [Vacuum] to perform the vacuuming operation. After 3 to 4 seconds, turn off [Exhaust], and then turn off [Vacuum].
4. Click [Descend], wait until it stops, then turn off the [Safety Lock].
5. Click “Start”, the device begins to work and the test starts.
6. Click [Back] to return to the main page.
7. When three specimens are found to be leaking in the layer being operated on, it indicates that the color of the specimens is red, the test is completed, and the test for this layer will automatically stop.
8. Select the completed floor of the test and enter by inputting the password.
9. Repeat [Step 3]
10. Unlock the [Safety Lock], then click [Rise]. After it stops, remove the test piece.Automatic Sealing Concrete Impermeability Tester
