| The NB-930 Stand- alone CO detector could be one of the most advanced designs in detection Carbon Monoxide using British Electro-Chemical sensor (the electro-chemical sensor is the only sensor type that meets both the most strict new
European EN50291 and UL2034 standards.) Battery powered models last long life (exceeds 3-year period and up to 5-years), It's the perfect choice for detecting dangerous CO poisoning. Various power input can be manufactured according to customer's special request. |
