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 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 the 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 each have
sockets at the front, into which spring clips may
be inserted for attachment of U-tubes.
The demonstration unit (> 664 400) rests on
two stable plastic feet; its height is adjustable.
The CPS demonstration unit (> 664 407) is
designed for use in a panel frame.
