pH/CO2 controller set

[crazyfrog]

guys im in a pickle here, i recently bought a pH/CO2 controller set consisting of pH controller 7070/2 and CO2 valve set 7074.11 with power supply unit 5012.01. in singapore unknowingly the power adaptor i bought is 220 50hertz (which makes sense because that is what they have in sg) .

now my question is can i buy a generic power adaptor that will work with the ph controller?

what should i get?
the specs of that adaptor is 9-12v 220 50herts

You just need an adapter that is tip positive, 2.5mm by 5mm tip size. It needs to have an output of 800mA or more and 9V.
