You can easily measure the power consumption of your devices with the Ansmann energy monitor APM2. Simple operation The measurement device quickly and reliably determines the most important current values. Easy to operate with only 4 buttons. The large display can be read easily and shows the related values at a glance. Individually programmable Your individual electricity tariff per kWh can be programmed very easily on the device. Both the consumption in kWh and the cost amount can be read directly. As long as the measurement is running, the time is recorded in order to make even clearer statements about the power consumption. Secure storage of data The built-in NiMH buffer battery is automatically recharged and keeps the values reliably up to 100 days in the memory even after disconnection of the device from the socket.
