  • Description

    High Sensitivity and User-Friendly Interfaces

    Models 3905 and 3910 deliver a minimum sensitivity of 0.3 µm, enabling detection of ultra-fine particles. The 3920 features a 0.5 µm lower detection limit while benefiting from its higher sampling flow rate. All units are equipped with a large colour touchscreen and intuitive operating interface. Preloaded with multiple cleanroom standards, they help users complete measurement and certification workflows efficiently.

    Enhanced Environmental Monitoring Capabilities

    An optional Climomaster hot-wire environmental sensor can be connected to measure air velocity, temperature and humidity. This upgrade turns the 3900 Series into an all-in-one instrument for cleanroom qualification and comprehensive environmental monitoring.

    Portability and Compliance

    Lightweight and compact, these counters are easy to carry for field technicians. Fully compliant with ISO 21501-4, they support cleanroom certification down to ISO Class 2. Pre-configured multi-standard modes cover ISO 14644, FS 209E, BS 5295 and EC GMP, streamlining certification work.

    Built-in Printer and Extensive Data Logging

    Every unit in the 3900 Series comes with an integrated printer and internal memory for up to 10,000 records. Users can print results on site and maintain complete records conveniently for reporting and data review.

    Cleanroom-Friendly Design and Extended Features

    The stainless steel housing is suitable for cleanroom environments. Optional accessories include a differential pressure sensor and a spare lithium-ion battery to extend operating hours.

    The Ultimate Choice in Cleanroom Measurement

    With flexible configurations, high sensitivity and practical user functions, the Kanomax 3900 Series portable particle counters are powerful tools for cleanroom testing. They are the ideal solution for professionals needing accurate, portable and multi-functional particle counting equipment.
