Abstract
Method, apparatus, and system are utilized for testing the performance of a gas monitor against predetermined monitor characteristics to determine if performance of the gas monitor is validated in a manner whereby testing gas is directly delivered to the gas sensor.
Claims17
A method of testing performance of a gas sensor assembly, comprising:
- providing a fluid coupling apparatus;
- applying a testing gas adjacent a gas sensor assembly from the fluid coupling apparatus;
- obtaining a first reading value of testing gas;
- storing the first reading value;
- obtaining a second gas sensor assembly reading value;
- determining a rate-of-rise value of the first and second reading values of the gas sensor based on a difference of the first and second reading values relative to a testing time interval therebetween;
- and
- determining if a gas sensor assembly passing condition exists based on a comparison of the rate-of-rise value of the first and second reading values to at least a first predefined rate-of-rise value of the gas sensor assembly.
