Quick Take
Choosing a portable particle counter for environmental indoor air measurement means matching the instrument's condition and fluid capability to your workflow. The four options listed here range from a repair-oriented TSI handheld to a HIAC liquid particle counter, with a Climet CI-1054 and a Pall PFC400W in between. The HIAC is the only unit described as used; the TSI is the starting point if you plan your own repair work. The Pall provides a middle option.

Product Notes
Climet CI-1054 Portable Particle Counter
The Climet CI-1054 is a portable unit from the United States. The device has scuffs and scratches, and the display glass is cracked. It was power tested only, with no full functionality check performed. It includes a power cord. Choose this if you need a spare parts source or can refurbish a portable counter. The cracked glass and for-parts-or-not-working condition mean you should not expect accurate particle counting out of the box. Repair expertise is required before this unit can serve as a measurement tool. The MPN is C1-1054-01.
HIAC 8011+ Portable Liquid Particle Counter
The HIAC 8011+ stands out as the only unit described as used and recently operational. It was last used in June 2025, saw roughly 70 uses, and always passed calibration. The package includes the vacuum pump and all hoses and cords associated with the particle counter. Pick this if your environmental indoor air work also covers hydraulic oil or other liquid cleanliness monitoring. The HIAC is a liquid particle counter rather than an air-only meter, and its upfront cost is the highest in this comparison. The exact calibration standard is not identified, so you may need to determine that yourself before using it in a regulated process.
Pall PFC400W Portable Fluid Cleanliness Monitor
The Pall PFC400W powers on when connected to a power source. Pressing 'Start Test' triggers immediate mechanical activity from the internal pump or motor; the initialization sequence was stopped manually to protect internal components because the monitor was not connected to a fluid line. The unit has not been calibrated or verified for measurement accuracy. Consider this when you want a confirmed power-on behavior and a fluid cleanliness monitor that can be connected to your system later. Without calibration verification, treat any future readings as unverified until the monitor is set up and checked. Its country of origin is Germany.
TSI AeroTrak 9306-V2 Handheld Particle Counter
The TSI AeroTrak 9306-V2 is a 6-channel handheld particle counter that powers on and operates, but testing indicates its particle count readings are inaccurate and the exact cause has not been diagnosed. It is sold explicitly for parts or repair, so it is not a ready-to-use instrument. If you can troubleshoot optical or flow issues, this is the most economical source for a replacement unit or donor parts. The unit's country of origin is the United States. Because the exact cause is not diagnosed, budget for open-ended troubleshooting time before the counter can produce dependable readings.
Final Recommendation by Use Case
- Pick the HIAC 8011+ if you need a liquid particle counter and the included vacuum pump and hoses are part of your workflow.
- Pick the TSI AeroTrak 9306-V2 if you want the lowest-priced entry point for repair and can spend time troubleshooting.
- Pick the Pall PFC400W if you need a power-on confirmed fluid cleanliness monitor and are prepared to handle verification separately.
- Pick the Climet CI-1054 if you are shopping for portable particle counter parts or have the ability to refurbish a unit.
For environmental indoor air measurement, a repair-oriented purchase can make sense if you can bring a non-working unit back to service; the only liquid-focused counter in this set with a recent use history is the HIAC, and the only sub-$600 option is the TSI.
