NE7-CO-H carbon monoxide sensor from Nemoto

NE7-CO-H Range - Hydrogen Immune

Special 4-Electrode Industrial Carbon Monoxide (CO) Sensors

General Description:

The NE7-CO-H range are two new electrochemical gas sensors with 4 electrodes, for the detection and monitoring of Carbon monoxide (CO). The sensor is particularly suitable for applications where zero sensitivity to Hydrogen is essential, such as Flue Gas Analysers and Anti-smoking breath-testers. The performance of the sensor is designed to conform with EN 50379 in Flue Gas Analysers. These sensors require a special circuit.

Nemoto's porous electrode technology enables accurate gas detection with high sensitivity. The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage. 2 Options are availablle:

NE7-CO-H (0-1000 ppm range)

NE7-CO-H10000 (0-10,000 ppm range)
