Equipment cooling air path monitoring (most commonly used)

Projectors, medical equipment, industrial cameras, industrial control computers: Monitoring cooling fan wind speed / air volume, filter blockage alarm, anti-overheating

HVAC ventilation and fresh air system

Small ducts, air outlet of air conditioners, fresh air equipment: Measuring wind speed, determining air pathness, feedback air volume

Air purifiers / purification equipment

Monitoring filter blockage, fan failure, intelligent reminder for filter replacement

Fan / fan status monitoring

Server fans, vehicle fans, small blowers: Real-time detection of abnormal wind speed, blockage, stoppage

Laboratories / small flow monitoring of instruments

Dry air, nitrogen, etc. low flow rate monitoring (non-explosion-proof, non-corrosive environment)

III. Comparison of FS7002 Series (Selection Reference)

FS7002-A: 0–2 m/s, ±4%FS → Low wind speed / High sensitivity

FS7002-B: 0–5 m/s, ±3% FS → General medium range (most commonly used)

FS7002-C: 0–10 m/s, ±2%FS → High wind speed / Large air volume
