Principle
According to the relevant provisions of the relevant international coating stain resistance test methods, the stain performance of building exterior coatings is tested by controlling water flow and time parameters.
Applications
Building exterior coatings - Determination of stain resistance
Steps
1. Connect the AC220V 50Hz power supply
2. Set the required test time (0~ 99h99s)
3. Fill the tank with an appropriate amount of water
4. Start the instrument for testing
5. Record the results after the test is completed
Notice
• Power supply voltage AC220V 50Hz before use
• Regularly check whether the insurance is in good condition (3A)
• Keep the water tank clean to avoid clogging the water pipe
• Operate strictly according to the time setting range
• Pay attention to observe the running status of the instrument during the test
