this basic Paramecium model demonstrates ciliate structure and single-celled organism anatomy for biology teaching

sized for precision-resistor and thermocouple work where stable resistance matters

this analog DC microammeter measures 0-100uA at 2uA resolution on a tabletop housing

this plug-type resistance box lets students see the switching action of each decade

Designed to make turns-ratio behavior tactile
