Proof of Clean Air, Recorded at Every Rack
CardSampler™ records airborne particles silently for months or years — until the day you need the evidence.
- Free of Charge: For data centers and data center service providers — shipping included
- Records For Years: Super tough PET, no power, no maintenance, tamper resistant
- Proof When It Matters: Renovation dust, smoke, extinguishing gas releases — or a hardware vendor blaming your air
- Swiss Lab Reports: Return anytime for analysis to ISO 14644-1 & ISO 8502-9
Free Incl. Shipping
Free of charge for data centers and data center service providers. Tell us how many — we ship them to you.
Tough & Tamper Resistant
Super tough PET, no power, no moving parts. Mounts at every rack and stays out of the way.
Months or Years
Collects particles & corrosive salts continuously — the record is there when an event or dispute arises.
ISO Lab Reports
ISO 14644-1 particle concentration, ISO 8502-9 surface chlorides, optional particle type, size & fiber analysis.
Mount It Once. Have the Proof When You Need It.
Like a flight recorder for your white space: it runs silently in the background and only needs attention when something happens.
Order Free
Tell us how many cards you need — ideally one per rack. We ship them free of charge.
Mount at Every Rack
Attach a card to each rack, air intake or technical room. No power, no wiring, no maintenance.
Records 24/7
Cards passively capture airborne particles, corrosive chloride salts and fibers for months or years.
Return When Needed
After an event, or when proof is requested, return the card anytime to our Swiss laboratory for processing.

Passive Particle & Corrosive Salt Recorder
Tamper resistant and made of super tough PET, CardSampler uses passive electrostatic charge to trap airborne pollutants — capturing fine PM2.5 fractions, nanoparticles, and airborne chlorides that optical room sensors and air filters miss.
Electrostatic collection field draws fine (PM2.5), ultrafine, and corrosive salt ions into engineered collection wells for Swiss laboratory analysis.
Available Lab Reports
- Particle concentration per ISO 14644-1 — verify ISO Class 8 for data center white space.
- Surface chlorides per ISO 8502-9 (chloride ion concentration).
- Optional: particle type, particle size distribution, and fiber analysis.
One Event Is Enough to Need the Evidence
Particle events are rarely planned. CardSampler has been recording long before anyone asks what was in the air — so the proof already exists.
Renovation & Building Work
Event: Drilling, sanding or demolition in or near the facility sends fine dust through the building and into the white space.
Evidence: Particle concentration and particle type at rack level — before, during and after the work.
✦ Documented proof for claims against contractors.
Smoke Events
Event: A nearby fire, an overheated component or smoke drawn in by the HVAC system.
Evidence: Lab analysis of what actually reached the racks — particles, soot and corrosive chlorides.
✦ Basis for insurance claims and damage assessment.
Extinguishing Gas Events
Event: An extinguishing gas release — triggered or accidental — stirs up settled dust at high velocity and can carry combustion by-products into IT equipment.
Evidence: Particle load and chloride deposits at the equipment, not just in the room.
✦ Clear record of the event's impact on your hardware.
When a Hardware Vendor Blames Your Air
Event: A hardware vendor rejects a warranty claim, arguing the air was not clean enough.
Evidence: Independent Swiss lab report showing whether ISO 14644-1 Class 8 was met — recorded right at the failed equipment.
✦ Independent proof that your air met the requirements.
