Product descriptionThe US-09 CO & H₂ dual gas detector is a reliable solution for monitoring carbon monoxide (CO) and hydrogen (H₂) concentrations in battery charging rooms. It is particularly suitable for lead-acid and lithium battery rooms – the former emit H₂, while the latter may emit CO or other organic pollutants in the event of a battery failure. Application: works perfectly in enclosed spaces – warehouses, laboratories, industrial charging areas – where constant monitoring is necessary. Key benefits: Two critical gas types are monitored simultaneously – reducing the number of devices and the installation burden. Two-level signaling ensures timely warnings – both alerts and evacuation start. The OLED display provides clear real-time concentration values. Universal integration into ventilation or alarm systems via relay outputs ensures efficient operation.
PurposeMonitor carbon monoxide and hydrogen concentrations in enclosed spaces and provide an alarm when gas concentrations reach dangerous levels. Early indication that gas emissions are beginning.
work environmentBattery charging locations Charging lead-acid batteries releases H₂. Charging lithium batteries releases CO, organic vapors, H₂ (in case of failure). Industrial charging rooms (forklift, EV, UPS battery rooms). Warehouses, laboratories, test stations where battery testing or charging takes place. Manufacturing plants where processes with hydrogen components are used.
Signals typeSound signal (dB), visual signal (LED indicators).
