Ian, Legally, probably yes. However, your choice of harmonised standard for the power supply may be called into question unless the operating environment of the gas monitor is within the bounds of the minimum operating environment specified in EN60950. One of the main differences between EN60950 and EN61010-1 is the range of operating environments and installation categories specified in EN61010-1. EN60950 really does not make any provision for Pollution Degree or Installation Category. I would try to set out a case that shows that EN60950 meets the requirements for this particular instrument (as detailed in the published specification)and document that case as part of your safety documentation. If you cannot make the case, then you have answered your own question.
