The energy transition places new demands on test technology: wall boxes, charging stations and charging cables have to be tested in compliance with standards and inspected regularly, photovoltaic modules should be checked for power output and open-circuit voltage before installation, and heating engineering relies on precise temperature measurements at flow and return. Testboy offers you specially developed test instruments and adapters for this – for Mode 2 and Mode 3 charging infrastructure, for PV panel testing and for multi-channel temperature measurement, from initial commissioning to periodic inspection.
