Why HN01001
Precise
Accurate detection across 0–4 vol% H₂, with alarms in under 10 seconds.
Long-lasting
A 10-year sensor core means fewer replacements and less downtime.
Low maintenance
Stable over the long term, so calibration and inspection costs stay low.
Low power
Ultra-low power design for 24/7 monitoring.
