The ECOTOX is a portable “disposable” gas detector which detects Oxygen (O₂), Hydrogen Sulphide (H₂S) or Carbon Monoxide (CO). The ECOTOX is compact, rugged and easy to use. The ECOTOX thanks his name to the combination of it’s ECONOMICAL feature: “low cost of ownership” and TOXIC gases. The detector is activated with a one-button action and will operate continuously during two years without maintenance. The remaining life span is continuously displayed in months, then days and then hours. When the user is exposed to a level of gas in excess of the alarm level, the ECOTOX will demand attention. The detector alarms with a loud audible signal, a rapid flashing visual alarm as well as an internal vibration alarm.
