PTD - 3G (Portable Testing Device) is a portable electronic device for on site meter testing, measurement of instantaneous values and profile recording. The device also provides some features of network quality monitoring. It is suitable for testing of single-phase and three-phase electricity meters on site, for energy quality and network parameters monitoring.
Wide range of functions, user - friendly interface, and sizeable graphical LCD applicable for diagram indication makes the working with this device easy, accurate and attractive.
