664 407
CPS electrochemistry demonstration unit
With this demonstration equipment from LEYBOLD DIDACTIC, you now
have available a universal power supply and measurement instrument which
can be used to conduct a broad variety of experiments from the field of electrochemistry.
Combining three functions in a single unit considerably reduces
the required preparation time while at the same time simplifying the actual
experiments.
The measured voltages and currents are displayed simultaneously and independently
of each other on a red LED display, the digits of which are 26 mm
high. The numbers can be read clearly even from a distance of about 10
metres. The demonstration unit fulfils three purposes:
- It functions as a power supply, delivering AC and DC voltage.
- It is equipped with two measurement instruments
a) for voltage measurements from 0 ... 60 V
b) for current measurements from 0 ... 2 A
Thus it can also be used as a multimeter. The measurement unit and the
power pack can be linked internally or can also be used separately. This unit
also serves as a current indicator and load using the built-in miniature motor
with segmented display disk. Additional instruments (chart recorder, CASSY
interface or oscilloscope, for example) can be connected to the two chart
recorder outputs (one each for voltage and current). Included as standard
equipment for the demonstration unit is a tray with recesses for the vessels
(e.g. battery tray from accessory set (> 664 401).
The CPS version (> 664 407) requires the use of the “table for
electrochemistry” (> 666 472) in addition. In both versions a white rear
panel serves as the background to accentuate colour changes, precipitation
reactions, etc. The tray and the table have sockets at the front, into which
spring clips may be inserted for attachment of U-tubes.The CPS
demonstration unit (> 664 407) is designed for use in a panel frame.
