Enclosed Oven and Control Unit Make Experiment Easy, Convenient and SafeUp to eight individual transition peaks can be displayed on the oscilloscope trace used with this unit—clearly showing the quantum jumps in mercury first found by Franck and Hertz.A metal cabinet houses the tube and oven. Two panels of the cabinet are clear, allowing for visibility of the tube. Another panel has a plainly-marked diagram on the outside, showing where to make connections to the tube. A thermometer fits in the top of the oven cabinet.The set contains a mercury Franck-Hertz tube; an oven with a built-in temperature controller; a control unit; and a shielded cable with BNC connectors. The oven and control box run on 110 VAC, 60Hz line voltage. The apparatus has a temperature range of 150° to 200°C. The tube is heated to about 170°.Specifications:Tube:3 electrodes; contains small amount of liquid mercuryMax. tube acceleration voltage: 70VControl unit outputs:Modes: Manual (for voltmeter) or xy-recorder; ramp for oscilloscope or PC interfaceFranck-Hertz signal: 0-12VAccelerating voltage: 0-7V (1/10 of actual, for voltmeter)Controls:Set potentiometer for heater voltage, acceleration, reverse bias and amplifier gainPower: 110VAC/80W; cord length 1.7m.Size: 23.5 x 23 x 17.5cm.Oven:Thermostatically controlled temperature, max. 240°CTube permanently mounted in ovenPower: 110V/450W; cord length 1.7mSize: 17 x 19 x 33.5cm.
