CST-222 (EVSE Digital Multimeter) – Digital Wallbox tester

Index: 01-19001
The CST-222 is a compact, user-friendly device designed for testing EV charging stations. It performs functional tests without the need for additional equipment such as a multimeter. For complete safety testing, it can be connected to a standard installation tester. By simulating an electric vehicle, charging cable, and common fault conditions, it verifies whether the charger complies with key standards (IEC/EN 61851-1 and IEC/HD 60364-7-722). With a clear 2.4″ graphical LCD display, it shows the most important output values of the EV charger, helping you quickly verify performance.
