It has a nice multi-colored display, showingVoltage (Volts AC)Current (Amps)Time (since last reset)Energy Consumption (kWh, since last reset)Power (Watts or kW)Power Factor (applies to electric motors)Frequency (Hertz)Temperature (degrees Celsius only - sorry no Fahrenheit option; if sensor is plugged in) Package Contents: Display module, opening transformer (used to measure energy flow) with about 6 inches of wiring, NTC temperature sensor with 16 inches of wiring, instruction manual. Please see photos for measurements. Wires on both, the temperature sensor and the transformer can be extended as needed. The transformer is the opening type, which makes it a lot easier to place it over the load wire to be monitored. Important: Please make sure it is placed over only one wire, either line or neutral. If placed over both they will cancel each other out and no reading takes place. The module has a programmable alarm function for Volts, Amps, Time, Energy consumption, Wattage and Temperature. It sounds an alarm when a preset value is exceeded. The alarm can also be disabled if not needed. Rating: Single phase 120/240 Volts AC (up to 300 max), 0 - 100 Amps load. Please see photos.
