Handheld Particle Counters

Handheld particle counters are essential tools for routine life sciences environmental monitoring. They offer fast, flexible measurement near critical activities, helping teams verify conditions, investigate alarms, and document results in support of GMP processes.

Common use cases include:

• Verifying laminar flow workstations and isolators before aseptic tasks.
• Assessing background conditions after maintenance or cleaning.
• Triaging alarms from remote sensors and determining next steps.
• Supporting ISO 14644 classification with localized measurements.

TSI handheld counters focus on usability. Clear interfaces guide users through sampling, while cleanroom-friendly construction supports wipe-down between areas. Lightweight designs and accessories make it easier to reach tight spaces and maintain consistent sampling geometry. Data can be stored, tagged by location, and exported to documentation systems to support traceability and audit readiness.

By deploying handheld counters alongside portable and remote devices, life sciences organizations can create a tiered monitoring strategy. Handheld tools handle point checks and rapid investigations, portable counters conduct extended studies and mapping, and remote instruments provide continuous oversight. Together, these layers help teams align monitoring with process risk, maintain situational awareness, and respond quickly when conditions shift.

TSI handheld particle counters are designed to provide stable measurement performance and efficient operation, allowing quality and operations teams to use them daily without undue complexity. The result is a practical way to collect consistent nonviable particle data that supports facility control and GMP decision-making.
