this hydrometer ships in a hard plastic protective case

reconfiguring the demonstration meter as a low-voltage voltmeter for single-cell and battery-pack readings

sized to mount alongside a tone generator for converting electrical signals into audible tones during sound-wave demonstrations

this ten-piece brass hooked weight set pairs five 50-gram and five 25-gram pieces with retractable hooks on both ends

showing equal pressure transmission across different piston areas

Copper-Iron Thermopile Lab Supplies_Tongs this hydrometer ships in aSeven junction copper and iron thermopile from four 130mm wires of each metal, the series arrangement amplifying the Seebeck voltage for radiant heat detection experiments.
