Probe Sampling Tubing
Sampling tubing conveys the gas to be analysed to the instrument. It usually consists of several leads – the so-called chambers: one for the gas, a further one for the electric wire for temperature measurement at the probe tip and, if applying, a third one to measure the chimney draught. Sampling tubing is available in different lengths. A special version thereof are NOx/SOx tubings which are used i.a. by the NOx measurement.
