Probe holder

THIS ELEMENT IS ORDERED SEPARATELY, YET IT IS ESSENTIAL TO WORK WITH ANALYSER!
Together with an exchangeable gas probe pipe is a complete gas probe for extraction of gas sample.
It has single gas tube ended with quick coupler and electric cable ended with a 4-pin connector.
Gas probe pipe is mounted with a M30x1 fitting.
Probe holder is equipped with an in-line filter with a condensation trap (recommended pore size of the filter inlet is 5µm).
Probe holder is available in two versions:

heated (with a slit for a filter for soot measurement test)
unheated (without a possibility to perform soot test)

Ordering codes can be found here

Gas probe pipe

THIS ELEMENT IS ORDERED SEPARATELY, YET IT IS ESSENTIAL TO WORK WITH ANALYSER!
Exchangeable gas probe pipe mounted on the probe holder with M30x1 fastening.
It has thermocouple type K (in some configurations type S) for measurement of gas temperature and a threaded fixing cone. With the probe holder is a complete gas probe.
There are many probe pipes available. They differ in length and working temperature.
For work efficiency it is advised to own different probe pipes to be able to adjust to the measurement place.
