It's a Triplett 3444 / Westmore 501 that has been enhanced.
This tester uses regulated power sources for the bias, plate, & screen voltages, as well as modified operating & testing procedures.
Filament voltage is also controlled.
Tubes are tested in accordance with the manufacturer's specifications; measurements closely align with a laboratory tester built to rigorously measure vacuum tube characteristics.
Tubes can be accurately matched for gm & plate current at the manufacturer's specified test points or at other specified test points.
