SF₆ Gas Comprehensive Tester
CBA‑2SFH SF₆ Comprehensive Tester
All‑in‑one SF₆ tester for purity, humidity (dew point) and decomposition (SO₂ / H₂S / CO ± optional HF) with fast, gas‑saving on‑site measurement.
Purity 0–100% ±0.5%Dew point −80…+20 °C, fast responseSO₂/H₂S/CO (HF optional)

Features & benefits
3‑in‑1 testing
