Details & Specifications
The AQS StoxPro is a compact fixed single-gas transmitter built on EC Sense (Germany) solid-polymer electrochemical sensing. Each unit is ordered for one target gas — 25 versions are available — and additionally reads temperature and humidity alongside the gas concentration (via RS485).
- Hydrogen versions: 0–1000 ppm · 0–5000 ppm · 0–5 %vol — built for H₂ leak detection
- Other target gases: CO, O₂, H₂S, NH₃, NO₂, SO₂, O₃, Cl₂, HCN, HF, HCl, PH₃, SiH₄, ETO, HCHO and more (25 total)
- Response: initial response < 3 s on ppm ranges (the 0–5 %vol range responds slower)
- Output: 4–20 mA or RS485 Modbus-RTU (selectable at order); temperature/humidity data on RS485
- Power: 12–24 V DC
- Housing: stainless steel · three front covers — Diffusion (standard), Duct-mounting (M18×1.5), Flow (Ø4 mm hose ports)
- Protection: IP66 · operating −40 °C to +55 °C
- Intrinsic safety: Ex ia IIC T6 Ga (GB/T 3836, certificate CCRI 24.7685)
- Warranty: 12 months
Applications: hydrogen power systems — fuel cells, industrial gas plants, battery energy storage, H₂ refueling stations — plus general toxic-gas monitoring.
