An analyzer and diagnostic system can include one or more sensors that are operable to generate combustion condition data relating to the performance of an associated combustion system. An analysis module can be operable to analyze at least a portion of the combustion condition data and determine a state of the associated combustion system. A diagnostic module can be operable to identify one or more recommended corrective actions for a combustion system performance deviation from a plurality of recommended corrective actions using one or more logic algorithms. Handheld instruments and methods of analyzing and diagnosing combustion processes are also included.

A gas sampling device including a chamber assembly formed of a chamber base having a chamber top mounted thereto is disclosed. A gas sensor is mounted to the chamber base in fluid communication with a gas flow passage therethrough. A motor is mounted to the lower surface of the chamber base and has a shaft extending through the chamber base. A fan is mounted onto the motor shaft within the chamber housing. An inlet flow passage extends through the chamber top above the center of the fan and an outlet flow passage extends through the chamber top above the gas flow passage. The fan and the chamber top are provided with a particular configuration to provide for efficient and smooth flows of gas through the housing and to the sensor. 5

An electrochemical cell for use in gas detection includes a cell body having an electrolyte cavity and a separate sensor cavity. The sensor cavity holds stacked sensor elements including a counter electrode, electrolyte mat, reference electrode and sensing electrode. A wick draws the electrolyte from the electrolyte cavity to the electrolyte mat. The sensing electrode closes off the sensor cavity and seals the counter and reference electrodes therein. The only gas which contacts the counter and reference electrodes is that which passes through the sensing electrode or is generated by the counter electrode and becomes dissolved in the electrolyte.
