PerfectPrime AQ9600, PM 0.3/2.5/10 Μm Air Quality Particle/Dust Detector/Counter

Accurately detects dust and debris in the air from smoke, cigarettes, pollen, and fire. The charger that comes with it is questionable but works and the interface takes some getting used to but is usable. The internals of this device are a bit of a mess and i founds bits of loose solder inside that i cleaned out.

Unit worked first couple of times I tried it... and never again. Now readings all zeros. Sample fan runs for 38 of the 50 second sample interval; then stops. Readings all show zero. History shows 11 runs, first 8 or so before I received the unit, all numbers in the 35 to 50 range. After receipt the numbers were low, 6 to 8 for two readings, now zeros. Unit falsely advertises it has HCHO measurements (formaldehyde) - it doesn't. Third imported/no-name air test device that failed to work at all or as advertised. So I am done with imported junk. Unless a seller has a US storefront I can walk into, or an office I can visit, my dollar will stay in my pocket.

I bought this thing right before the Canada wildfires caught up with us in the northeast US. The picture above was after a few readings to get things stabilized. This is most deffinitly not a normal reading. I am in no way a professional, I just needed something to tell me whether my flow hood was blowing sterile air or not. For these purposes, this device seems to be fantastic. It reads zero along the inner square and starts to show small particles along the leading edge where the flow would whip around dirty air. The 50 second test time is fine, it gets the job done as long as you leave it completely alone during each run. I can reliably mark off my work area with this tool; I've had remarkable success working with cultures within this clean air bubble. I had purchased another similarly expensive unit that was not nearly as accurate as this one. So far so good.

We have a class 10,000 clean room. The device seems to work fine outside the clean room, where for the 0.3um particles, I measure 25,000 particles/L. However, inside the cleanroom, as soon as the particle concentration goes below 7,000, ithe device suddenly indicates zero for all particle sizes. I expected the reading to be about 1,000 /L for the 0.3 um particles. Update: the item was returned and we purchased Dylos DC1700 instead. This one works perfectly as expected.

It’s difficult to know how accurate the absolute measurements are, but it seems to check out comparatively from room to room, area to area. Seems to be one of the best options if you want to identify the dustiest areas of a building or determine a before vs after when installing an air filtration system.

I used this to test the air quality of my flow hood. I read the manual to see how to switch it to particles / Liter and then took a base line reading in the room 30,000 0.3 um/L, I took a reading in the flow hood and kept hitting run to watch the hood go form 30K to 0 particles per liter. Works great.

The tester was working for only a few samples. It was working somewhat for about 8 samples, then it stopped reporting the particle counts. It only displays zeros now. Edit: Raising my review to 2 stars. The tester does work if the environment is not clean. There appears to be some calibration or firmware bug that if the environment is too clean, it does not register the particle counts and the final result becomes 0. If they can fix the firmware, this product would be good.

It detects PM 0.3um and the price is amazing!! Like it when I first switch it on. Durable and well made outer case. Clear color rich LCD display which is easy to read even in the dark. It detects PM with the size 0.3um, 2.5um and 10um all at the same time. Choose from different sampling frequencies and test modes etc... Got temperature, humidity and memory for data storage too.There are two measuring units -- ug/m3 and piece/L. The smallest particle it can accurately count is up to 0.3um (In piece/L only, piece count make more sense than weight when particles are that small). The one I have got from Dylos can only detect particles up to 0.5um in size. And you know what, this one is even way cheaper.
