1. Large air permeability, fast gas humidity flow and exchange rate,  uniform divergence.  it is far superior to other peer products with the optimization of special process in HENGKO.

2. Excellent ability of anti-dust, anti-corrosion and waterproof（IP65）

3. Protecting PCB modules from dust, particulate pollution and oxidation of most chemicals to ensure sensors a long-term stable operation, higher reliability and long service life

4. Remarkable performance in harsh environment such as small space, long distance space, pipe, trench, wall pass mounting, high pressure space, vacuum chamber, test chamber, large flow mediums, high humidity area, high temperature and heat environment, hot drying process, dangerous zones, explosive environment containing explosive gas or dust, etc

5. the HENGKO stainless steel porous houisng for sensor probe, have accurate pore size, uniform and even-distributed apertures. Pore size range: 5μm to 120 micron; it have good filtration dustproof and interception effect, high filtration efficiency. The pore size, speed of the flow and other performances can be customized as requested; Stable structure, particles are tightly bound without migration, almost inseparable under harsh environment.
