Extra Dense Flint Equilateral Glass Prism, 48mm, R=1.62 Subcategory_Buchner Funnels Highest-decade single-dial resistance box stepping

Highest-decade single-dial resistance box stepping from 100k to 1M ohms in 100k-ohm increments

Widest-range 17-coil plug-type resistance box covering 1 ohm to 10k ohms with 21

and specific-heat comparisons

heavy duty

dropping the bulk of the measured potential across the external resistor so the coil sees only its proportional share of the signal

Extra Dense Flint Equilateral Glass Prism, 48mm, R=1.62 Subcategory_Buchner Funnels Highest-decade single-dial resistance box steppingPairs equilateral 48 by 48mm shape with extra dense flint glass at refractive index 1. 62, the lead flint body delivering pronounced dispersion through a 60 degree triangular cross section.
