Energy meter GreenBlue GB615E with LCD display for power and energy monitoring

Portable energy meter GreenBlue GB615E with an LCD display provides real-time monitoring of electrical power and cumulative energy consumption. Designed for simple insertion between mains socket and appliance plug, it displays instantaneous power (W) and accumulated energy (kWh), enabling users to observe consumption patterns and estimate operational costs for individual devices. The compact form factor and clear numeric LCD make it suitable for spot measurements in homes and small offices.

Advantages

The device delivers direct numeric readings on an LCD screen for both instantaneous power and cumulative energy, allowing quick assessment without additional equipment. Its portable plug-in design requires no installation, making it convenient for temporary or repeated measurements. The unit supports monitoring of a wide range of household and office appliances, helping to identify energy-intensive devices and plan usage more efficiently.

Suitable for

• Measuring power consumption of kitchen appliances (microwave, kettle, toaster)
• Monitoring office equipment such as PCs, printers and monitors
• Checking standby power of consumer electronics (TVs, set-top boxes)
• Estimating running costs of heaters, fans and air purifiers

Key specifications

• Luminous LCD numeric display for instantaneous power and cumulative energy
• Measures instantaneous power in watts (W) and accumulated energy in kilowatt-hours (kWh)
• Plug-in portable form factor for direct connection to a mains socket
• Suitable for single-phase household and small office loads
• Compact size for easy placement and storage

How to use

Insert the energy meter into a standard mains socket and then plug the appliance into the meter’s outlet. The LCD will show the instantaneous power draw; cumulative kWh will be displayed and updated as the appliance runs. For accurate cost estimates, record the cumulative energy reading at the start and end of the measurement period and multiply the consumed kWh by the local electricity tariff. Do not exceed the device’s rated load and follow safety guidelines printed on the product.

Usage recommendations

Use the meter for intermittent tests of individual appliances rather than continuous monitoring of large inductive loads. Periodically reset the cumulative reading when starting new measurement sessions to keep results clear. Avoid using the meter in damp or exposed environments and ensure the connected appliance’s power rating falls within the meter’s operational range.
