Important safety alert for TESTO 330 Flue Gas Analysers

Important safety alert for TESTO 330 Flue Gas Analysers

Fireplace.co.uk has been made aware of a possible error in firmware on two models of flue gas analysers manufactured by Testo.

We understand that this affects Testo 330-1 and 330-2 flue gas analysers, but only the version with the grey housing and black-and-white display (production period 2006-2011) and Firmware version 2.02. If you own a newer testo 330 with black housing and colour display, this does NOT affect you.

Testo has discovered an error in Firmware version 2.02 which causes the instrument to display an incorrect value when measuring ambient CO content while using the flue gas probe. This causes the instrument to display no CO content, even if the ambient air does contain levels of CO. In such circumstances there could be an increased risk for personal safety and this could lead to serious health damage.
 
If you’re in doubt as to whether your analyser may be affected or would like further information please contact Testo Customer services:
