Wattmeter - energy consumption meter The meter allows you to easily measure the energy consumption in your home/workshop. This allows you to control energy consumption on an ongoing basis, and thus you will be able to quickly check which devices in your household consume the most energy. Knowing which devices consume the most electricity, you can easily reduce energy consumption by limiting the operation of these devices to a minimum. By reducing your energy consumption, you will also reduce your electricity bills. Equipped with a large, legible display and 4 intuitive buttons to control the device. The meter also allows you to measure current (A), voltage (V), frequency (Hz). After entering the rate for 1kWh, the device will calculate the amount of energy bills. Product features: displays the current power of the device connected to the meter allows you to calculate the amount of electricity bills (after entering the rate for 1 kWh) allows you to measure current, voltage and frequency by using an energy consumption meter you will be able to easily reduce energy consumption and thus save money easy-to-read, large display 4 intuitive buttons to control the device Technical Specifications: Recording time range: 0 seconds - 9999 days Power range: 0.0W - 9999W Voltage range: 0.000V-9999V Frequency measurement: 0Hz-9999Hz Energy consumption measurement: 0 ~ 9999 kWh Energy display: 0~9999kWh reset button Maximum load: 16A, 3600W Voltage: 230VAC 50Hz
