Франк-Герц Эксперимент машина с Ar-Тюбе

DH4507 Franck-Hz Experiment Apparatus(Ar-tube)What you can learn: 1. Electron collision. 2. Excitation energy. 3. The exit of atomic energy level. specification 1. DH4507 Franck-Hz Experiment Apparatus Heater volt: DC 0 5V, 1A, ±1%;The first grid volt VG1K: DC 0 6V, 2mA, ±1%; The spurn volt VG2A: DC 0 9V, 2mA, ±1%; The second grid volt VG2K: DC 0 90V, 2mA, ±1%; Adopt switch to cut over the display of the four-way volt, 31/2 digital display, use regulation resistance to change the volt;The second grid volt can be controlled by both internal and external voltage about 0-4.5V corresponding to a output voltage about 0-90V. Just press the cut over push button, it can be connected to external Data acquisition to realize the automation control of the second grid voltage;Current measurement range: 1nA 1999nA,31/2 digital display, minimum resolution 1nA;Ar-tube is fitted in a transparent synthetic glass, visual to see;2. DH-DS3 Data acquisition One channel analog signal output, range 0 5V, 10bits D/A output; One channel analog signal input, 41/2 bits A/D, sampling frequency 3Hz/sone channel oscillograph signal output and one channel trigger signal output, use to display the Franck-Hz curve in the oscillograph , 12 bits high speed D/A to output the signal, standard interface to oscillograph ;PC interface: USB or RS232;Configuration: conventional type DH4507: To survey the excitation voltage of Ar-atomic manually, to draw the volt-ampere characteristics curve and research the quantum leap. Configuration in detail: DH4507 Franck-Hz Experiment Apparatus + Ar-tube testing jig Intelligent type DH4507B: Add data acquisition to the conventional type, which can automatically survey volt-ampere characteristics curve and still display it dynamically in the oscillograph.Configuration in detail: DH4507 Franck-Hz Experiment Apparatus + Ar-tube testing jig+ DH-DS3 data acquisitionnot including PC interface. Microprocessor-based type DH4507A: Add PC interface and experiment software to the intelligent type, which can do all the experiment in the computer. The software has single sampling and continuous sampling two methods, friendly interface and easy to operate.Configuration in detail: DH4507 Franck-Hz Experiment Apparatus + Ar-tube testing jig+ DH-DS3 data acquisitionincluding PC interface+ computer software. Except the three types above , we still have the Type DH4507M, which is a combination of DH4507 and DH-DS3. We can offer it according to user.
