-Besides above meters, we also stock the ET340 meter; REL300300000. It counts energy in a different way than the EM24. For Germany and most other countries; the EM24 is the advised model. See FAQ Q5 and Q9 for details.+The EM24 meter counts energy in a different way than the ET340. For Germany and most other countries; the EM24 is the advised model.
