The device that catches electricity actually doing work, not just showing up.
means An instrument that measures electrical power — the rate at which electrical energy is being used or delivered — in watts.
from A straightforward compound: 'watt,' the unit of power named after James Watt, the Scottish engineer whose steam-engine improvements made him the go-to namesake when scientists needed a unit for 'work done per second,' plus the ever-useful suffix '-meter,' from Greek 'metron' (measure), which English bolts onto almost anything we want to quantify — thermometer, speedometer, and so on. Put them together and you get exactly what it says: a meter for watts.
