Test principle: OcPTextile Testing Instruments, Testing Equipment Manufacturer

1. Neutral salt fog test (NSS) is a test in the control environment for atomization in the control environment method. OcPTextile Testing Instruments, Testing Equipment Manufacturer

2. The acetate Mist Test (AASS) is a test method of 5%sodium chloride acid solution that will be added to the controlled environment for atomization. OcPTextile Testing Instruments, Testing Equipment Manufacturer

3. Copper accelerated acetate mogo test (CASS) is 5%sodium chloride acid solution of copper chloride and methampionic acid in the control environment for atomization. A test method. OcPTextile Testing Instruments, Testing Equipment Manufacturer

Configuration of sodium chloride solution: OcPTextile Testing Instruments, Testing Equipment Manufacturer

1. At ± 2 ° C, the conductivity is not higher than 20US/cm distilled water or dissolved sodium chloride in de -ionic water, and is prepared to form a solution with a concentration of 50g/L ± 5g/L. The concentration of spray liquid collected should be 50g/L ± 5g/L. At 25 ° C, the relative density of the preparation solution is within the range of 1.029 ~ 1.036.

Main features:

OcPTextile Testing Instruments, Testing Equipment Manufacturer

1. The temperature control instrument uses a microcomputer PID control instrument, high control accuracy and good stability, which effectively guarantees the fluctuation of temperature and humidity fluctuations Scope and test operation; OcPTextile Testing Instruments, Testing Equipment Manufacturer

2. Temperature control adopts P.I.D + S.S.R, the system is coordinated by the same channel, which can improve the stability and life of the control component and interface use, touch button formula setting A variety of pictures are displayed directly; 3. Automatic water adding water purification filters to ensure that the pipeline is not blocked and the service life is longer. (In this industry's first creation) 4. The laboratory water level is too high -automatic overflowing device without manual emissions, but the warming time will not be too long. 5. The heating system uses a titanium alloy heater, and the corrosion resistance will never rust, and there is a repair port. 6. The pressure barrel is made of SUS304 stainless steel. The pressure barrel is also known as the saturated air barrel is part of the core part of the salt fog test box.Therefore, also known as saturated barrel
