Digital-to-Analog Converter Glassware_Glass Bottles Continuously variable 100V-5kV output shown

Continuously variable 100V-5kV output shown on a 0-5kV digital voltmeter

suited to fieldwork in geography units and orientation activities outside the classroom

sized for finer-gauge resistance demonstrations and small-scale heating elements where the heavier gauges would over-deliver current

Meter-stick optical bench fitted with two supports

Research-grade oxygen spectrum tube at 26cm with a 10cm central capillary

Digital-to-Analog Converter Glassware_Glass Bottles Continuously variable 100V-5kV output shownConverts a 3 bit binary input (0V 5V logic) into a 0 to 7V analog output, pairing with the companion ADC unit to demonstrate the sampling process and quantization loss.
