Bench Digital pH Tester, EI 0962 (Discontinued) Length_125mm running as either water turbine

running as either water turbine or motor-driven pump for fluid-based energy-conversion work

supplying a finer-gauge option for precision resistors and standard-cell construction in physics labs

flame heating the bar until thermal expansion stops it from passing through the gauge opening

Hand-painted skin cross-section enlarged 300 times exposes epidermal layers

Used to test how mass per length controls pitch
