I've been looking at testers today and was told about the Metrel gear on here. Quite taken by the amount of punch they seem to pack forwhat you pay, been looking at the MI3000 an MI3100 the only difference between them is the 3100 has a remote test probe and will test type B RCDs on pv installations. They are quite cheap hence why am asking if anyone has used them and could tell me what they think, cheap and cheerful or a serious competitive bit of kit? If I do go for one it will probably be the MI3100 so i won’t look quite the plumb with the lovely blue and yellow colour scheme of the MI3000.
