Product Overview

The GCC-WIT-2ii is a compact, portable aerosol photometer engineered for HEPA/ULPA filter integrity testing and in-situ leak detection in pharmaceutical manufacturing, food production, semiconductor fabs, and other controlled environment industries.

The instrument detects defects including pinholes in filter media, frame sealing issues, gasket leakage, and structural leakage at filter housing interfaces. By comparing upstream and downstream aerosol concentrations, the WIT-2ii enables rapid identification of leakage points. A 3.5-inch handheld scanning probe allows operators to accurately locate remote or hard-to-reach areas, with automatic audible and visual alarms when leakage exceeds preset thresholds.

Why It Matters: With a detection sensitivity of 0.0001% and ±1% reading accuracy, the WIT-2ii delivers reliable HEPA/ULPA filter validation compliant with ISO 14644, IEST, and NSF 49 standards — essential for GMP audits, cleanroom commissioning, and biosafety cabinet certification.

Frequently Asked Questions

What is the detection sensitivity of the GCC-WIT-2ii?

The WIT-2ii features a display range of 0.0001% to 100.0%, enabling detection of extremely small filter leaks. This sensitivity level meets the stringent requirements for HEPA and ULPA filter integrity testing in pharmaceutical GMP and semiconductor cleanroom environments.

What aerosol types are compatible with the WIT-2ii?

The WIT-2ii supports PAO (polyalphaolefin), DOP (dioctyl phthalate), DEHS (diethylhexyl sebacate), and other polydisperse aerosols commonly used for HEPA/ULPA filter testing. The instrument is calibrated for consistent measurement accuracy across all supported aerosol types.

Is the WIT-2ii suitable for NSF 49 biosafety cabinet testing?

Yes. The WIT-2ii is fully compliant with NSF 49 standards for biosafety cabinetry field certification. It is widely used for in-situ filter leak detection in Class II biological safety cabinets, laminar flow workstations, and other containment devices requiring periodic filter integrity verification.

How many test records can the WIT-2ii store?

The instrument supports up to 100,000 total measurement records. In storage mode, up to 6,000 records can be saved per test session. Data can be exported for reporting and compliance documentation. The device also supports continuous real-time monitoring and direct printing modes.

What is the handheld scanning probe used for?

The 3.5-inch handheld scanning probe enables operators to scan filter surfaces, frame seals, and gasket interfaces to precisely locate leakage points. The probe features a synchronized display and one-key operation, making it easy to identify remote or hard-to-reach defects during in-situ testing.

What is the recommended calibration interval?

We recommend annual calibration to maintain measurement traceability and compliance with ISO 14644 and IEST standards. GCC provides factory calibration services using traceable reference standards to ensure ongoing accuracy for regulatory audits and quality assurance programs.
