Product Introduction

This portable particle counter uses laser light scattering and a controlled internal pump to sample substantially larger air volumes than a handheld spot-check instrument. Its stainless-steel, wipe-clean housing, large touchscreen and removable battery arrangement are suited to room-to-room qualification work. Configurable sampling plans, location records and electronic data transfer help validation teams execute repeatable surveys while preserving the context of every result.

Key Features

High-flow sampling shortens the time required to collect representative cleanroom air volumes.

Multiple particle-size channels support simultaneous classification and contamination diagnosis.

Chemical-resistant stainless-steel exterior tolerates common controlled-area cleaning agents.

Guided sampling locations and stored recipes reduce operator variation during qualification rounds.

Internal HEPA-filtered exhaust prevents sampled particles from being released back into the test area.

USB, Ethernet and configurable wireless connectivity support paperless result transfer.

Customer Product Concerns

Large-volume classification rounds demand faster collection, repeatable recipes at every inspection point, and records that remain traceable when results are archived.

Low-flow instruments can make one-cubic-metre sampling rounds excessively slow.Select 28.3, 50 or 100 L/min configurations to match the required sample volume and available qualification time.

Paper printouts and manual transcription can weaken data integrity.Electronic recipes, user controls, audit-ready records and direct data transfer keep results associated with the original run.

Cleaning chemicals may damage instruments repeatedly moved through classified rooms.A smooth stainless-steel exterior is compatible with routine wipe-down using commonly specified cleanroom disinfectants.

Variable inlet tubing can create particle losses and inconsistent readings.Defined isokinetic probes and controlled tubing lengths provide a repeatable sampling path for each survey.

Typical Applications

ISO cleanroom classification and periodic requalificationRoutine pharmaceutical environmental monitoringLarge-volume sampling in aseptic processing areasHEPA-filtered room recovery and contamination investigationsSemiconductor and precision-manufacturing clean-zone surveys
