The system enables standard membrane integrity tests to be performed safely in hazardous industrial areas.\n\n\u003ch3\u003eTechnical overview\u003c\/h3\u003e\nFiltration processes involving solvents, alcohols or volatile chemicals are often operated in classified ATEX zones. In these environments, testing equipment must comply with explosion protection requirements.\n\nAn ATEX filter integrity tester allows verification of membrane filter performance while meeting safety requirements for operation in hazardous areas. The device performs the same integrity test procedures used for membrane filtration validation in pharmaceutical and industrial filtration systems.\n\n\u003chr\u003e\n\n\u003ch2\u003eOperating principle\u003c\/h2\u003e\n\nThe tester applies controlled gas pressure to a wetted membrane filter and measures the resulting gas flow or pressure behaviour.\n\nTypical integrity test methods include:\n\n\u003cul\u003e\n\u003cli\u003eForward flow \/ diffusion testing\u003c\/li\u003e\n\u003cli\u003eBubble point testing\u003c\/li\u003e\n\u003cli\u003ePressure hold

ratings\u003c\/h2\u003e\n\nIntegrity testing instruments verify membrane filters across a wide range of filtration ratings rather than performing filtration directly.\n\nTypical membrane filters tested include:\n\n\u003cul\u003e\n\u003cli\u003e0.1 µm sterilizing grade membranes\u003c\/li\u003e\n\u003cli\u003e0.2 µm sterile filtration membranes\u003c\/li\u003e\n\u003cli\u003e0.45 µm
