Abstract
An apparatus for determining a presence, a concentration or a change in concentration of a target material in an environment is disclosed. The apparatus comprises first and second sensors configured to respond to the target material. The apparatus further comprises a fluid inlet in fluid communication with the environment, and a valve assembly having a first and second configuration. In the first configuration, the fluid inlet is in fluid communication with only the first sensor. In the second configuration, the fluid inlet is in fluid communication with the first sensor and the second sensor.
Claims18
Apparatus configured to determine a presence, a concentration or a change in concentration of a target material in an environment comprising:
- first and second sensors configured to respond to the target material;
- a fluid inlet in fluid communication with the environment;
- a valve assembly having a first and second configuration, wherein in the first configuration, the fluid inlet is in fluid communication with only the first sensor;
- and in the second configuration, the fluid inlet is in fluid communication with the first sensor and the second sensor;
- a first fluid flow path between the fluid inlet and the valve assembly, wherein the first sensor is disposed in the first fluid flow path;
- a second fluid flow path between the fluid inlet and the valve assembly;
- and
- a third fluid flow path between the valve assembly and the second sensor.
