Frequently Asked Questions

What is the difference between the three measurement channels (0.3, 0.5, 5.0 µm)?

The particle counter simultaneously measures particles across three size classifications. The 0.3 µm channel detects ultrafine particles, 0.5 µm captures fine particulates (ISO standard reference), and 5.0 µm identifies larger contamination events. Multi-channel measurement enables comprehensive cleanroom compliance documentation.

Is this particle counter suitable for ISO cleanroom certification?

Yes. The instrument is certified for ISO 5-8 cleanroom classification at 0.5 and 5.0 µm particle sizes. It meets JIS (Japanese Industrial Standards) zero count and counting efficiency specifications required for official cleanroom qualification.

What does '<1 zero count in 5 minutes' mean?

This specification indicates that when sampling particle-free air (through the zero-air filter), the instrument registers fewer than 1 false particle count during a 5-minute sampling period. Lower zero counts ensure measurement accuracy and sensitivity.

Can I export data to Excel or other analysis software?

Yes. The particle counter stores up to 10,000 measurements internally and exports all data via CSV format, which is fully compatible with Microsoft Excel, statistical software, and laboratory information systems (LIMS).

How long does the battery last?

The 4×AA NiMH rechargeable battery pack provides approximately 3 hours of continuous particle counting operation, sufficient for field sampling protocols. The AC adapter enables extended laboratory use without battery limitations.

What is the maximum particle concentration this counter can measure?

The instrument can measure up to 2,000,000 particles/ft³ at 5% coincidence loss. Coincidence loss (when two particles are counted as one) increases at very high concentrations. Dilution sampling may be required for higher contamination levels.

Is external software or calibration required?

The counter functions with internal firmware and integrated display controls. No external software installation is necessary for operation. Optional CSV data transfer software facilitates Excel import. Factory calibration maintains measurement traceability; recalibration is recommended per facility SOP.

What maintenance does the particle counter require?

Regular maintenance includes: replacing zero-air filters when saturated, cleaning the external ABS housing with methanol or neutral detergent, verifying battery charging cycles, and periodic optical system inspection. Refer to the user manual for detailed maintenance schedules.

Can I connect the particle counter to a printer for automated reporting?

Yes. The RS-232 interface (9600 baud rate) supports connection to external thermal printers. The instrument generates single, multiple, or continuous measurement printouts with ISO classification calculations and certified documentation.

What is the sampling head, and why is it included?

The isokinetic sampling probe maintains representative air velocity at the measurement inlet, ensuring accurate particle collection regardless of ambient air speed. This is essential for valid cleanroom certification and reproducible environmental monitoring.
