PCI4/750
Potentiostat/Galvanostat/ZRA

The PCI4/750^™ is a higher current version of the PCI4/300 Potentiostat.  The PCI4/750's small size does not compromise its performance.  Its output is a healthy ±750 mA at ±12 V.  This is especially useful when testing batteries, fuel cells, or electrochemical systems with very high corrosion rates.  Its 9 current ranges and post gain offset capability allow for a maximum resolution of 2.5 fA (gain=100).  16-bit D/A and A/D converters, along with four terminal current and voltage measurements, provide accurate results down to 1 µV resolution.  On-board electronics allow EIS scans from 10 µHz to 300 kHz, without the need for an external FRA or lock-in amplifier.  Extensive voltage and current channel filtering allows quiet measurements in very noisy environments.  A state machine insures accurate data acquisition timing, even when you run other applications on your computer.

For a complete assessment of the ability of the PCI4/750 to perform EIS, see the Accuracy Contour Plot.

The PCI4/750 is fully isolated from the computer's chassis ground, so it can work with earth grounded cells.  It offers both current interrupt and positive feedback IR compensation.  It works in the field, even when your computer is powered by a generator or a battery power inverter.   Extra I/O interfaces are available to control other equipment.

• Isolation - Our potentiostats  were designed by electrochemists for the real world.  All Gamry potentiostats are fully isolated (electrically) from the host computer's chassis ground, allowing it to function properly with earth grounded cells.  Use the PCI4/750 with autoclaves, mechanical stress apparatus, or pipeline probes for  accurate results.
     
• Excellent Engineering - Gamry's modern electronic design and extensive use of surface mount technology packs tremendous capability onto a small area.  The performance and reliability of a potentiostat is not proportional to the volume or weight of the potentiostat!
   
• Current Interrupt and Positive Feedback iR Compensation -  no need to rig your cells with supporting electrolyte or geometric modifications anymore, Gamry potentiostats and their controlling software use control loop algorithms to accurately measure and correct for uncompensated resistance.
   
• Portability -  All Gamry potentiostats were designed to be used in the field as well as a controlled laboratory environment.  Gamry potentiostats will will fit in any portable compuer containing 2 PCI slots.  Their power supply circuit design  allows for battery and generator powered portables.
   
• Auxiliary I/O - All Gamry potentiostats allow you to control additional equipment via additional I/O interfaces.
  
  external signal input
  analog voltage output
  analog current output
  auxiliary A/D input
  miscellaneous I/O connector:  this 15-pin connector provides a number of inputs and outputs to customize an electrochemical experiment, including a software-controlled analog output voltage, two fixed triggers, 4 software-controlled input triggers, and 4 software-controlled output triggers.
     
• Power Supply - Potentiostats use the computer's power supply, eliminating the need for extra cables and clutter.
   
• Scalability - Up to eight Potentiostats can be installed in one computer. 
    
• Built-In EIS - On- board DDS to perform EIS from 10µHz to 300kHz.
  
• Easy Installation - The PCI4/750 is a Plug and Play Device, so installation is automated and easy.

The PCI4/750™ is protected by a  2-year factory service warranty.
