Very low sampling rate, avoiding clogging issues, and immediate dilution at the sampling point
Transfert of the sample gas (up to 150m) by an unheated line, with no risk of condensation
Minimum maintenance of the probe (several months of unattended operation)
Calibration control of the monitoring system by direct injection of span gas directly at the top of the probe
No electricity or moving part in the probe and sample line
Low installation cost
Remote maintenance possibility via serial output
Multiprobes: from 1 to 4 probes connected to a single set of analyzers

Maximum sample gas temperature:

standard probe: + 400°C - quartz probe: + 600°C

Dilution rate: 12/1 to 350/1 according to the type of critical orifice selected (sampling from 20ml/mn to 500 ml/mn)
Accuracy of dilution rate: ± 2 %
Compressed air: 400 Nl/h, 5 to 7 bars
Probe dimensions: 27 mm external diameter, 60 cm standard length (body made of special alloy)
Umbilical cord length: 5 to 150 m
MS1 housing : 19`` rack / 4U
