General Description
The NT-CO-LI Cell is a new electrochemical gas sensor with
3 electrodes for the detection of carbon monoxide (CO) in
a variety of gas detection applications. Exhibiting high
performance with long-term stability, the NT-CO-LI includes
a built-in chemical filter for the removal of alcohol and
other interfering gases. This compact (20.4mm dia) sensor is designed to
offer a ow cost but high performance option in low cost light industrial
applications.

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.
The integral gas filter is made with absorbing materials
that effectively remove cross-sensitive gases and vapours
such as alcohols, hydrogen Sulphide nitrogen dioxide, and
sulphur dioxide. The filter results in the excellent gas
selectivity of the NT-CO-LI.
