Use argon tube without heating

Compare to other gases (such as mercury vapor), no heating required, and its chemical properties are more stable, less experimental process in highly excited states of atoms, better results on accuracy and Error.

Wide voltage power supply design

Switchable between 110V and 220V, suitable for use in most countries.

BEX-8502B Auto sampling Franck-hertz Experiment Apparatus

Integrated design, using single-chip microcomputer to control current and voltage, can manually or automatically complete the experiment.

Use argon tube without heating.

Three argon tube structures are available: 360-degree visible structure, external structure, and built-in structure.

The instrument uses mechanical buttons to adjust the experimental parameters, which greatly increases the service life.

The instrument uses LCD screen to display various experimental data, which is convenient for recording experimental results.

Experimental Data

Note: the datas are tested with PASCO sensor. If you need sensors, you can consult your local PASCO Reseller for purchase.

Parts List
