1470E系列

儀器介紹　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　  The Multi-channel system consists of one or more
1470E multi-channel potentiostats and multiple
145x series frequency response yzers (FRAs)
connected to a computer providing simultaneous
DC and impedance tests on multiple cells. Each
1470E unit provides eight fully independent
potentiostats, allowing up to eight separate cells
to be tested simultaneously. Each channel is
completely independent allowing the same or
quite different experiments to be run on each
cell.
The CellTest system provides a wide range of
experimental techniques, including charge /
discharge, potentiostatic, potentiodynamic,
galvanostatic, galvanodynamic, fast cyclic
voltammetry, open circuit, fast pulse and step
techniques, ohmic-drop ysis and impedance.
Simultaneous impedance tests can be run on
multiple cells by connecting Solartron 145x
series frequency response yzer (FRA)
modules to the 1470E. These FRAs can operate
in single sine correlation or multi-sine / Fast
Fourier Transform (FFT) ysis mode, providing
the ultimate in speed, precision and accuracy.
The 1455 FRA provides high performance
impedance measurements over the frequency
range 10µHz to 1MHz, while the 1451 FRA
operates from 10µHz to 100kHz.
Temperature controlled ovens and furnaces
can be added to the system and automatically
controlled from the PC over a serial
communications link, providing the facility
to test cells at different temperatures (for
example for testing solid oxide fuel cells at up to
1000ºC).技術(shù)參數(shù)? *Specification
Eight independent potentiostats per 1470E
Multiple 1470E units per system
10,000 measurements per second (100 microsecond sample rate)
Simultaneous voltage and current measurement
16-bit og to dial converters (high accuracy + high speed)
Each experiment step can have different measurement rate (e.g. low sample rate while charging, high rate during pulses) plus “measure on change”
Limit checking at high speed to ensure cell safety
10V/-3V, &plun;4A per channel
Floating electrodes (allow parallel channel connection – high current)
Ethernet control (position equipment and computers where needed)

**Options
Eight auxiliary voltage measurement inputs
Eight temperature measurement inputs (high temperature applications e.g. Solid Oxide Fuel Cells)
Control outputs (to control power boosters, valves, switches etc.)主要特點*Simultaneous high-speed impedance
measurements on all channels
*Single sine correlation and multi-sine / FFT
impedance measurement techniques
*Impedance and DC measurements of cell
anodes and cathodes (14702A option)

test cells.
*High rate data acquisition during DC
tests at up to 10,000 samples per
second (allows fast cyclic voltammetry or
G mobile phone pulse tests)
*4-terminal cell connections, essential for
testing very low impedance devices such
as batteries and fuel cells.
