As winter approaches and the nights draw in it is very important that engineers keep their flue gas analysers in a warm place overnight.

Going from a cold van to a warm room may affect the performance of your flue gas analyzer and may damage the sensor.

When this happens the oxygen or carbon dioxide reading will generally be displayed as “- - - -”

If you suspect a problem following your analyser getting cold, leave the analyser running in a warm place, with the pump 'ON', sampling fresh air for a few hours (use the mains adapter/battery charger if you need to).

If after doing this you are still experiencing problems, please contact one of our service departments.
