Another meter you can add to the list is the
Metrel MI 3360 M. (Must have the M designation so it includes the IEC 62353 tests). Also the GMW TG euro 1 med and the Gossen Metrawatt Secutest Pro (M7050-V003) can perform IEC 62353 testing including applied parts. I see the GMC Secutest Pro is also listed on the
RS website.
Also to answer the original posters question, IEC 62353 (BS EN 62353) should be used in the UK as mentioned in the
MHRA Managing Medical Devices (2015) publication. This states not to use 60601-1 tests (page 22) and to use 62353 (page 24).
