Quick Take
Buying a particle counter is not as simple as picking the cheapest number. The harder question is what you are actually measuring: airborne particles in an indoor environment or particle contamination in a fluid system. These four portable units split into two groups. The Triplett EPC175 and Particles Plus 8306 are built for air monitoring, while the Beckman Coulter HIAC PODS+ and Pall PFC400W are designed for fluid cleanliness. Knowing that split before you shop will save you from buying an instrument that measures the wrong medium.
Price Comparison
| Product | Price | Bar | Condition | Best For |
|---|---|---|---|---|
| Particles Plus 8306 | $1,499.00 | Used | Handheld air particle counting | |
| Beckman Coulter HIAC PODS+ | $399.99 | For parts or not working | Portable fluid particle counting for parts/repair | |
| Triplett EPC175 | $156.71 | New - Open box | Indoor air quality monitoring | |
| Pall PFC400W | $1,799.99 | Used | Portable fluid cleanliness monitoring |
Decision Matrix
- Need an indoor air quality meter at a low listed price: Triplett EPC175. It displays PM2.5 and PM10 counts, air temperature, relative humidity, formaldehyde, and TVOCs on a 3-inch color TFT screen, and stores 5,000 data sets.
- Need a handheld air particle counter with calibration documentation and included accessories: Particles Plus 8306. It was calibrated on October 4, 2024, and includes a hard case, AC adapter, and USB cable.
- Need a portable fluid particle counter for parts or repair: Beckman Coulter HIAC PODS+. It is sold as-is and has only been power tested, so it makes more sense as a repair project or parts source than as a measurement instrument.
- Need a portable fluid cleanliness monitor you can set up and verify yourself: Pall PFC400W. It starts its pump when Start Test is pressed, but it is not calibrated or verified for measurement accuracy.
Product Notes
Particles Plus 8306 Handheld Particle Counter Cal. 2024 w/ Case & Accessories
This used handheld counter is described as exceptionally clean, with very little sign of previous use. It powers on, the touchscreen responds normally, the air sampling pump operates, and menu navigation works. The calibration information was accessed and verified: the unit was calibrated on October 4, 2024, with a due date of October 3, 2025. It includes a hard carrying case, AC adapter, and USB cable, which makes the $1,499.00 price easier to justify if you need a ready-to-carry air counter. The main limitation is that the calibration due date has already passed, so you may need to schedule a recalibration before trusting readings for compliance or detailed analysis.
Beckman Coulter HIAC PODS+ STD B87403 Portable Industrial Fluid Particle Counter
This is the least expensive way into a portable industrial fluid particle counter at $399.99, but it is sold as-is for parts or repair only. The item was power tested only and shows wear and tear. That makes it a candidate for someone who repairs instruments, needs a spare parts donor, or wants to attempt a restoration. It is not a reliable tool for current measurement until the unit is thoroughly tested and repaired. If you are shopping for indoor air measurement, this is the wrong medium: it is built for fluid particle counting, not airborne particle counting.
Triplett EPC175 Particle Counter and Air Quality Meter, Displays Air Temperature
At $156.71, this is the lowest-priced unit in this group and the one most directly aimed at indoor air concerns. It displays PM2.5 and PM10 count, air temperature, relative humidity, formaldehyde (HCHO), and TVOCs. The 3-inch color TFT display has five brightness levels, and the meter stores up to 5,000 data sets for historical data curves. It runs on batteries, with a battery included, and also comes with an AC adapter and USB power/charging cable. The main limitation is the open-box condition: the packaging has been opened even though the meter is new. If you need a sealed retail box, that is the trade-off you are accepting for the low price.
Pall PFC400W Portable Fluid Cleanliness Monitor Particle Counter - Powers On
The highest-priced unit in this comparison at $1,799.99 is a Pall Corporation fluid cleanliness monitor made in Germany. It is used and shows typical signs of light professional use. It powers on when connected to a power source, and pressing Start Test triggers immediate mechanical activity with the internal pump or motor whirring normally. That test was stopped manually because the monitor is not hooked up to a fluid line. It has not been calibrated or verified for measurement accuracy, so expect to do your own calibration and setup before using it as a measurement instrument. It is intended for fluid cleanliness, not indoor air measurement.
Final Recommendation by Use Case
Start with the medium you need to measure. For environmental indoor air measurement, the Triplett EPC175 is the lowest-priced, ready-to-use choice, while the Particles Plus 8306 offers a handheld counter with calibration documentation and is the step-up option if you need a more capable air counter. For fluid cleanliness, the Beckman Coulter HIAC PODS+ is the lower-priced fluid option for parts or repair, and the Pall PFC400W powers on but needs calibration and fluid-line setup before you can rely on its readings.
