NC-1000
NC-1000
The combustible gas detector model NC-1000 is designed to detect leakage of combustible gases in a hazardous area continuously. The detection range of NC-1000 is 0 to 10,000 ppm. A sample of gas is drawn by the internal small pump. Only AA alkaline dry batteries are used for power supply.
The dry batteries cannot be replaced in a hazardous area.
