R-GAS-FLAMMABLE
Award-winning hydrogen and off-gas detection
R-GAS-FLAMMABLE is a dual-function sensor developed for lithium-ion battery applications. It detects electrolyte off-gas (Stage 2) and hydrogen-containing flammable gas mixtures generated during thermal runaway (Stage 3).
Its calibration-free design reduces maintenance requirements while maintaining reliable detection performance in demanding environments.
Independent testing demonstrates faster response compared to legacy flammable gas detectors, supporting earlier alarm indication during battery events.
Choose R-GAS-FLAMMABLE when both early warning and thermal runaway gas detection are required in one device.

Stage 2 - off-gas detection
Listed electrolyte vapor (VOC) gas sensor platform
GAS-VOC is designed specifically for Stage 2 early warning by detecting electrolyte vapor released from lithium-ion batteries before thermal runaway.
By providing earlier indication of abnormal battery behavior, GAS-VOC helps operators intervene before escalation to flammable gas release.
Its modular platform design allows cost-effective deployment across BESS containers, battery rooms and UPS installations.

Stage 1 — Abuse (prevention) detection
Modular & listed sensor platform
Most battery incidents originate outside the cells. Stage 1 detection focuses on preventing escalation by identifying external hazards such as water leaks, overheating, or environmental anomalies before they become electrical fires.
This prevention layer is what makes Prevent-iON a complete platform rather than only a gas detection system.
