REAL-TIME MONITORING - Measure and calculate power (w), energy (kWh), current (A), voltage (V), frequency (Hz), CO2 emissions (kgCO2), the power factor, cost, maximum supply voltage, power, power factor, frequency and CO2 equivalent in real time. You can also view this accumulated data by day, week or month. DUAL TARIFF AND SINGLE TARIFF - Added dual tariff mode, you can set two electricity tariffs at different times as needed to calculate electricity costs more accurately .OVERLOAD ALERT - You can set the power of the security alarm (not to exceed 3680W). When the load connected to the socket exceeds the set value, the large LCD will flash OVERLOAD to warn the user. It helps you control the power consumption of electrical equipment and ensure electrical safety. DATA RETENTION - With the built-in battery, even if the meter is unplugged from the outlet, the latest data will be saved. Dont worry about data loss due to sudden power failure. PARAMENTS - electric voltage: 230V AC 50Hz, maximum current: 16A, maximum power: 3680W, accuracy: +/- 2%, operating temperature: 0 C - 40C.Product DescriptionMaxcio Energy Consumption MeterIdeal for monitoring home appliance consumptionMeasure and calculate monitoring equipment power (W), total energy consumption (KWH), total cost electricity (COST), carbon dioxide emissions (KgCO2), voltage (V), current (A), power factor, AC frequency (Hz) and consumption history. Perfect for many devices such as computer, air conditioner, refrigerator, dishwasher, etc. Real-time monitoring Two tariffs Overload alert Data retention Large LCD screen The energy meter is built with a large digital display that can be seen from a distance and is very easy to read. Conserve energy By monitoring the electricity costs of household appliances, you can avoid excessive energy consumption, reduce costs and extend the life of equipment. Protection of overloadWhen the load connected to the socket exceeds 3680W, the second line LCD will display OVERLOAD to warn the user (optional).How to set the unit price of electricitySINGLE TARIFF (TARIFF 1)1.
