Electrochemical gas sensor assembly
First Claim
Patent Images
1. An electrochemical gas sensor assembly comprising an electrochemical gas sensor for sending a selected gas;
- a filter through which gas to be sensed must pass before reaching the sensor, the filter including means for filtering out at least one non-selected gas to prevent said at least one non-selected gas from reaching the sensor but permitting passage of the selected gas; and
a temperature control system for controlling the temperature of the filter.

Abstract
An electrochemical gas sensor assembly comprises an electrochemical gas sensor for sensing a selected gas. A filter is provided through which gas to be sensed must pass before reaching the sensor, the filter being adapted to prevent at least one non-selected gas from reaching the sensor but permitting passage of the selected gas. A temperature control system controls the temperature of the filter.
