Quick Take
When you are choosing an environmental indoor air measurement tool, the first question is what you are sampling: room air or industrial fluid. This comparison covers one new air monitor and three portable particle counters. The Air Quality Monitor, PM0.3/2.5/10 Dust Particle Counter is the only ready-to-run indoor air monitor in this set. The other three are industrial or controlled-environment units, so the core decision is whether you need live airborne readings or a specialized particle-counting tool for fluid and cleanroom work.

Product Notes
Air Quality Monitor, PM0.3/2.5/10 Dust Particle Counter, High Sensitivity 3-Chan
The Air Quality Monitor, PM0.3/2.5/10 Dust Particle Counter is the only new unit in this comparison. It uses laser scattering to measure airborne particle sizes, adds temperature and humidity, stores 999 timestamped measurements with a trend chart, and includes an adjustable audible alarm. For a home or office looking for a direct indoor air measurement solution, this is the model to use without fluid-line connections. The limitation is its scope: it samples air, not hydraulic or lubricating fluid. If your need is industrial fluid cleanliness, this monitor cannot serve as a substitute for the portable fluid particle counters listed here.
Beckman Coulter HIAC PODS+ STD B87403 Portable Industrial Fluid Particle Counter
If your goal is a repair project rather than an immediate working instrument, the Beckman Coulter HIAC PODS+ STD B87403 is the fluid particle counter to study. It comes in for-parts or not-working condition, and the only functional check is a power test. That makes it a candidate for troubleshooting, but it also means you should not expect accurate readings today. The visible wear and tear reinforces the project status. This unit is not part of the indoor air conversation; its intended job is industrial fluid particle counting.
Pall PFC400W Portable Fluid Cleanliness Monitor Particle Counter - Powers On
Among the industrial units, the Pall PFC400W is the one that gives you a useful sign of life. It powers on, and pressing Start Test causes the internal pump or motor to whir normally. That is a strong reason to consider it if you need a portable fluid cleanliness monitor and can complete setup. The corresponding limitation is that the monitor has not been calibrated or verified for measurement accuracy and was not connected to a fluid line during the check, so you would need to arrange that before treating its output as valid. The product shows typical light professional use and is sold as a used unit.
Climet CI-1054 Portable Particle Counter Cracked Glass See Photos Power Tested
The Climet CI-1054 is a specialty portable particle counter with a cracked display glass and scuffs from normal use. It is power tested only, and the unit includes a power cord. It is intended for reuse or repair/refurbishment, so treat it as a restoration candidate rather than a working instrument. If you want a Climet model for parts or refurbishment, this is the one to examine, but the cracked glass is a clear drawback and no functional test confirms the counting electronics. It is not aimed at environmental indoor air measurement, so keep it in the category of repair/reuse projects.
Final Recommendation by Use Case
For environmental indoor air measurement, choose the Air Quality Monitor, PM0.3/2.5/10 Dust Particle Counter. It is built for room-air readings and covers the main airborne particle sizes along with temperature and humidity.
If your job is fluid cleanliness, the Pall PFC400W is the used unit that powers on, but plan to complete calibration and fluid-line hookup before trusting its readings.
For a repair project, the Beckman Coulter HIAC PODS+ STD B87403 gives you an industrial fluid counter without the expectation that it works today.
For specialty refurbishment, the Climet CI-1054 is the project unit, with the cracked glass and power-tested status as reminders of the work ahead.
