OKet® flammable gas detectors are independently developed and produced by OKet®, based on the principle of non-dispersive infrared absorption. They are suitable for refueling stations, oil depots, petrochemicals, oil fields, coal mines, and other places where flammable gases exist in environmental protection and fire protection. It mainly monitors CH Combustible gas. When the detector reaches the alarm preset value, it will immediately send an alarm, and at the same time, the information will be transmitted to the flammable gas alarm controller of the alarm terminal, and the signal will be linked to the management and control platform to help managers to centralize and real-time the environmental conditions of all monitoring points monitoring.
Functions:
●Long life and high range.
●Real-time display of flammable gas concentration, sound and light prompt when reaching the alarm threshold.
●Fault self-check, display for normal, fault and alarm status.
●The alarm information can be uploaded online, which can be used in conjunction with other monitoring and early warning systems.
●Flameproof design, safe and stable.
There are two types of OKet® flammable gas detectors, wireless communication flammable gas detector ET01-L and wired communication flammable gas detector ET01.
