3.3 Sample
WARNING
IT IS IMPORTANT THAT NO FLAMMABLE MIXTURES ARE ALLOWED TO
COME INTO CONTACT WITH THE MEASURING CELL AS THIS MAY CAUSE
IGNITION OF THE GAS. GASES CONTAINING HALOGENS, SULPHUR OR
SILICON, MUST BE AVOIDED. IT IS THE RESPONSIBILITY OF THE USER
TO ENSURE THAT ANY ADVICE OFFERRED CAN BE SAFELY APPLIED TO
THEIR PARTICULAR SITUATION
CAUTION
THE DEW POINT OF THE SAMPLE MUST ALWAYS BE LESS THAN THE AMBIENT
TEMPERATURE TO AVOID THE RISK OF LIQUID DROPLETS FORMING IN THE
MEASURING CELL
3.3.1 Key requirements
• The sample must not contain halogens, sulphur or silicon (any silicones) as these will
poison the sensor.
• The sample must be non-condensing, non-corrosive and particle free.
• The sample exhaust must be at or near atmospheric pressure in all cases.
• When applied to heat-treatment atmospheres containing combustible gases, care
should be taken to ensure that the sample exhaust (sample out) is taken to a safe vent
where there is no risk of ignition.
