Choosing a portable particle counter for environmental indoor air measurement is not just about finding a model; it is about deciding how much repair risk you are willing to carry. The four listings in this comparison span a wide price spread and very different conditions. A low price can mean a parts-only unit, while a higher price can still leave you with a used instrument that needs attention. Start with how you will use the counter: do you need it working immediately, are you planning to repair it yourself, or do you need a specific model to complement equipment you already own?
Quick take
If you want a counter described as fully operational and tested, the Particles Plus 8306 is the only listing here that says so. If you want the least expensive entry point, the Beckman Coulter HIAC PODS+ is the low-price option, but it sits at repair level. The Climet CI-1054 is best for a buyer who specifically wants that model. The LASAIR III 310C gives you a used-excellent listing with the model name, but at the highest price in the group.

Product notes
Particle Measuring Systems LASAIR III 310C Portable Particle Counter
If you are looking specifically for a LASAIR III 310C, this is the one listing in the group with that model and a used-excellent condition. It is also the highest-priced entry here at $2,495.80, which makes it a significant commitment compared with the rest of the field. For a buyer who already knows this model and is comfortable with used-excellent gear, it is a direct match. If you are still comparing options, the price alone is enough to make you pause and weigh whether the model name matters more than the lower cost of other listings here.
Beckman Coulter HIAC PODS+ STD B87403 Portable Industrial Fluid Particle Counter
This is the entry-price listing at $399.99 and the only unit in this set whose title identifies it as an industrial fluid particle counter. The condition is listed as for parts or not working, it was power tested only, and it is sold as-is with visible wear and tear. If you are comfortable troubleshooting or you need a source of spare components, this is the least expensive way into the product category. The listed origin is the United States. Do not expect it to work out of the box; budget for the repair or use it as a parts donor. That makes it a niche choice, but a very affordable one if the risk fits your situation.
Climet CI-1054 Portable Particle Counter Cracked Glass See Photos Power Tested
The title makes the main caveat obvious: the display glass is cracked, and the condition is listed as for parts or not working. At $2,249.99, this is not a bargain repair project, but it is the only Climet CI-1054 here, and a power cord is included. The counter was power tested only, so the mention of normal scuffs and scratches plus cracked glass matters when you set your expectations. If you need this specific model to match existing equipment or you are prepared to replace the display, it may be worth the price. If you simply want a working particle counter, the cracked glass and parts-level condition make it a much harder pick.
Particles Plus 8306 Handheld Particle Counter Cal. 2024 w/ Case & Accessories
This listing is described as tested and fully operational, with touchscreen response, particle counting function, air sampling pump, and menu navigation all confirmed. It comes with a hard carrying case, AC adapter/charger, and USB cable, and the calibration information is dated October 4, 2024. The listed price is $1,499.00. The key limitation is that the calibration due date of October 3, 2025 has already passed, so if you need an active calibration for your work, you should plan to have the unit recertified before putting it into service. For a used handheld that appears to be the most ready-to-use option in this group, this is the most straightforward choice.
Final recommendation by use case
- If you want the least expensive route into a portable particle counter and can do the work yourself: Beckman Coulter HIAC PODS+ STD B87403.
- If you want the counter that is closest to ready-to-use in this group and can handle a calibration refresh: Particles Plus 8306.
- If you are set on the LASAIR III 310C and the top price is acceptable: Particle Measuring Systems LASAIR III 310C.
- If you need the Climet CI-1054 model and can repair the cracked display: Climet CI-1054.
