CO/H2S-D2 Carbon Monoxide + Hydrogen Sulfide Sensor (CO + H2S Sensor)

CO/H2S-D2 Miniature Size Carbon Monoxide + Hydrogen Sulfide Sensor Introduction
The world wide use of multigas, portable, personal safety monitors has grown since
the 1970s to include an ever increasing number of industries. The one requirement
in common to the majority of these instruments is the need to measure both Carbon
Monoxide and Hydrogen Sulfide simultaneously.

Alphasense now offers a compact, dual gas sensor which allows designers to reduce
significantly instrument size and cost. The D2 sensor provides a unique approach
to the dual gas sensor in both its size and working electrode configuration. The
use of a high capacity filter over the Carbon Monoxide working electrode
eliminates Hydrogen Sulfide cross sensitivity to Carbon Monoxide.

Proven in the field over many years, these sensors perform well even under long
term, challenging conditions.

• Range: 1000 ppm CO limit of performance warranty
