15V DC Interchangeable Dial for Demonstration Meter Lab Equipment_Lab Burners used to compare reactive-metal electrolysis

used to compare reactive-metal electrolysis behavior against carbon and platinum in the same apparatus

this 18 SWG bare constantan wire on a 125g reel relies on the alloy's low temperature coefficient

the moderate curvature spreading light gently for divergence and virtual-image-formation work in refraction demos

this LPG Meker burner also includes flame stabilization and flow control

15V DC Interchangeable Dial for Demonstration Meter Lab Equipment_Lab Burners used to compare reactive-metal electrolysisFifteen volt DC scale on a 315x115mm laminated panel with sealed multiplier, sized for stacked battery measurements when the demonstration meter is used at the higher voltmeter range.
