Handheld Airborne Particle Counters

Introduction

Handheld airborne particle counters provide portable measurement of airborne particle concentration in various environments. They are widely used in cleanroom inspection, HVAC system verification, and environmental monitoring tasks. The device allows flexible on-site testing and quick evaluation of air quality conditions. It solves the limitation of fixed monitoring systems by enabling mobile and rapid assessment. In practical use, it supports maintenance checks and compliance verification, helping users quickly identify contamination risks and airflow issues.

FAQ

What is the Handheld Airborne Particle Counter mainly used for?

The Handheld Airborne Particle Counter is used to count particles or determine particle size and distribution in air, liquids or samples. It supports cleanroom monitoring, filter testing, hydraulic-oil checks, environmental work and quality control.

Which standards and regulations apply to the Handheld Airborne Particle Counter?

The instrument is designed with reference to applicable ISO and GB/T standards for particle counting and cleanroom monitoring and IEC 61010 electrical safety. Procedures should follow the relevant standard. Compliance documentation can be provided on request.

How long is the warranty period?

A 12-month warranty applies to the complete equipment against defects in materials and workmanship. It excludes consumables, wearing components and accidental or misuse damage. Our service team handles claims against the serial number, and longer cover can be arranged.

How easy is the Handheld Airborne Particle Counter to use?

Day-to-day use is simple, with clear prompts and pre-set functions reducing manual steps. New operators should review the manual and complete a short familiarisation. Our technical team offers remote support during the first runs.

What is the typical lead time for order delivery?

Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.

Does the Handheld Airborne Particle Counter need calibration or verification?

To protect result reliability, periodic verification should be performed, typically once or twice a year. The instrument arrives factory-calibrated, and self-check routines help spot drift. We offer traceable calibration service if the site needs it.

Where do we get replacement parts?

Common consumables and standard spare parts are available through our service channel and are not locked to proprietary formats. Quote the model and serial number when ordering so the correct items are supplied. Lead time for standard parts is usually short.

Can it be adapted to our requirements?

The standard model can be configured with selected accessories and operating options to suit the task. Non-standard requests are assessed before quotation so the final build is clearly defined. We confirm details before production.

Do you provide on-site installation?

Standard installation is straightforward and supported by the manual and start-up documentation. Our technical team can guide staff remotely through checks and validation. On-site commissioning is available as a quoted service.

What maintenance and safety points matter?

Do not sample condensing or contaminated atmospheres, use a blocked inlet or skip flow checks. Keep the sensor clean and calibrated. Follow the operating instructions.
