This Electrical Consumption Meter Kit has four transmitters/sockets in which we connect various electrical devices and a digital receiver that works with batteries. You can measure your current consumption and calculate costs (previously added) of each of the connected devices (up to 4), as well as know the time periods, date, humidity and temperature. All of this is shown on the receiver, which has a large screen and is capable of transmitting data from up to 30m away, retains its memory even when disconnected and, within the settings, it can be programmed to sound an alarm if energy or costs have risen. Learn how much energy your new and old electrical devices consume, whilst functioning and whilst in standby (air conditioning, computer, fridge, television, coffee machine, lamps, game consoles, radios, etc.) easily and simply, in order to reduce costs and to know whether your electrical appliances are in working condition. *Batteries included.
