Gas analyzer unlocking in The Netherlands?

Thanks for the reply. I think you're right, will contact someone on Markplaatz and see what can be done. The annoying thing is that I know someone in the UK who used to do the calibrations, but he hasn't got the equipment anymore.
Contacting the distributor in the Netherlands has indeed got me nowhere with this, though they do still have the unit listed on their website.
