Gill AC
A high specification corrosion monitoring instrument for most AC/DC corrosion tests. Includes a potentiostat, galvanostat and zero resistance ammeter. Up to 32 Gill AC's can be run simultaneously from the same PC with independent control of each instrument. The Gill AC forms the basis of the Gill 8 and Field Machine ranges and can also be run parallel with these instruments.

Click Gill AC for more information.

Field Machine
Ruggedised laboratory instrument for use in the field. This instrument has its own power source with an outlet for the PC.
Additional power can be taken from the mains or a 12-24V source, such as a car power socket. All cables are provided together with a robust carrying bag.

Click Field Machine for more information.

Gill 8
Multiple sequential channel laboratory instrument. Typically used for testing inhibitors. Can be supplied as the Gill 4, 6, 8, 12 or 16 with the same number of channels. Cables included.

Click Gill 8 for more information.

Pot 16
Sixteen channel cathodic disbondment tester. Combines the reliability and simplicity of a manual instrument with single page software.

Click Pot 16 for more information.

Traditional Zero Resistance Ammeter, Potentiostat and Sweep Generator
Manual instruments for manual control. Ideal for very long term tests.

Femto Amp
Ideal for high impedance testing on paints and coatings.
Best used with a Faraday cage
Optional extra for Gill AC, Gill 8 and Field Machine.

Click Femto Amp for more information.

Isolated 30
For measurement of galvanic current and potential on up to 30 galvanic couples in the same electrolyte with optical isolation between channels.

Click Isolated 30 for more information.

LPR Meter and bespoke LPR Meter
A traditional battery/mains powered LPR Meter and a bespoke LPR Meter for in situ long term monitoring in the field.

Click LPR Meter for more information.

Designed for the research and development laboratory these instruments offer power, precision and performance. Housed in a modern 19" size case in contrasting white and grey, with brushed anodised aluminium front panel, they take pride of place in any laboratory. To reinforce the professional image, cell connections are made via military grade 5105 connectors. These are both attractive and very functional, immediately identifying the instrument as a serious piece of equipment.

This instrument offers a Potentiostat, Galvanostat and Zero Resistance Ammeter with integrated Frequency Response Analyser and Sweep Generator in one. It is based around a two Amp Potentiostat teamed with a two Amp Zero Resistance Ammeter and can be supplied as - 6 channel, with six sequential channels, 8 channel (eight sequential channels) or 12 channel (twelve sequential channels). Connection to the controlling Windows PC is via a standard RS232 port, optically isolated for full floating operation. The instrument is supplied with a full set of cables and software, user manual and application notes on CD.

We have made the Gill 12 for over 20 years, constantly improving it. The heart of the instrument is now a digital signal processor for faster AC and features better mains signal rejection. The 13 decades of current are measured by a 24 bit ADC as is the reference electrode voltage. The software includes all corrosion and electrochemical tests both DC and AC, IR Compensation, our unique test Sequencer and Analysis.

These instruments are the preferred choice of corrosion and electrochemistry laboratories around the world. Multiple cells speed up testing and increase reproducibility. Our new two year warranty is included with every ACM Instrument, this may be extended to five years at low cost.

Multiple Channel options available in any configuration from 2 to 12 channels.

Also available with higher current output up to 6 Amp in same size case. Higher current (over 6 Amp) output options are available too.

Also available in a smaller case (Gill AC style) with up to 6 channels.
