Abstract
A refrigerant analyzer including a pump, a filtering device, a temperature/humidity regulator, an electrochemical sensor, and a control device, wherein the refrigerant analyzer is configured to circulate conditioned air through the sensing chamber for an initialization duration of time to obtain an initial output value, determine whether the initial output value is stabilized below a predetermined initial limit, circulate a refrigerant through the sensing chamber for a sensing duration of time, operate the control device to measure a sensed output value, and operate the control device to determine a measured concentration of at least one contaminant within the refrigerant based on the sensed output value.
