Here, a concept needs to be clarified: what is CEMS? It is not an ordinary online analysis instrument. Ordinary users cannot choose the analysis items; this table is typically a four-in-one type that analyzes oxygen content, NOx, sulfur dioxide, and dust. You can choose to turn off certain analysis options; for example, when it comes to sulfur recovery, you can disable the dust analysis option. However, you cannot add new options – you can use separate instruments for carbon monoxide and hydrogen analysis, but you shouldn’t expect CEMS devices to have these analysis functions. The CEMS model may also be a **specified model or manufacturer locally; in some places, there is no choice available
CEMS generally **designate suppliers; to ensure data accuracy, it is important to choose an appropriate range that is not too large.
