  • Description

    Exceptional Sensitivity and Rapid Response

    Fitted with an Electron Capture Detector, the Q200 delivers detection sensitivity down to 0.01 ppm (10 ppb), capable of spotting tiny SF₆ leaks. It reaches 85% of the final reading within one second, with a recovery time of less than two seconds. This fast response supports efficient leak surveys and reduces testing downtime.

    Versatile Applications Across Industries

    The Q200 is built to satisfy demanding test requirements for multiple scenarios:

    • Fume hood and glove box containment testing to ASHRAE 110‑2016 and EN 14175
    • Building ventilation and re‑entrainment research
    • Hazardous material storage container inspection
    • Leak checking for high‑voltage switchgear and gas supply systems
    • Semiconductor manufacturing testing and military equipment maintenance

    Its wide adaptability helps maintain safety and regulatory compliance across varied working environments.

    User-Friendly Design and Data Management

    The ergonomic Q200 features a handheld probe linked to the main unit by a 10 ft (3.5 m) sampling line, making it easy to operate in confined spaces. The probe carries an alphanumeric VFD display to show real‑time values right at the measurement point. Other functions include:

    • RS232 port for data logging and connection to external systems
    • 0–2 V analog output for signal monitoring
    • Customizable audible alarm setpoints
    • Internal memory for up to 100 measurement records
    • Straightforward user calibration
    • Onboard diagnostic functions for system status checks
