Zero Resistance Ammeters
Current sinks are electronic circuits which can sink electric power in a controlled manner, thus acting as controlled loads. Our current sinks are designed as four - quadrant current sinks which can feed and sink currents in both polarities (also disregarding the polarity of the resulting voltage).

Weld Testers
The Weld Tester is our most versatile electrochemical monitoring instrument. Housed in a substantial metal case with brushed anodised aluminium front panel and green military specification connectors this equipment looks functional and professional. The top row of connectors are exactly the same as provided on a Gill 12 whilst the bottom row are for the additional weld segments. Using the same Potentiostat, Galvanostat, Zero Resistance Ammeter with integrated Frequency Response Analyser and Sweep Generator as a Gill 12 allows all the tests supplied with the Gill 12 to be supplied with the Weld Tester.

Biosensor isoPod with USB
EPU352
A compact signal conditioner for monitoring low current, two-electrode (anode and cathode) amperometric sensors. By setting the polarization voltage to zero it can also be used as a zero resistance ammeter (ZRA).Electrical isolation ensures that readings are not influenced by nearby current sources such as conductivity, or voltammetric electrodes.

Parallel systems
Did you know you can couple several Gill AC, Gill 12 and Weld Testers together or any combination of Gill AC, Gill 12 or Weld Tester, to give you a parallel logging multiple Potentiostat / Galvanostat / ZRA / FRA system, capable of recording from each working electrode at up to 60 readings per second. Coupling several Gill ACs or Gill 12s together gives the added abilities of the Weld tester and the ability to perform fast sweeps. Using our latest software, it has never been easier to couple instruments together to provide a Parallel System. In fact up to 32 instruments can be controlled at the same time. These instruments can either have individually enclosures or be rack mounted.

Recording Ammeter
Amcorder
The Amcorder uses the same sensor technology as the original Ampstik. The True RMS inductive sensor does not use magnetic materials and has no moving parts. The opening of the sensor is electronically closed and external currents are electronically rejected. The accuracy, external current reject, and range of currents measured by the patented amp sensor substantially exceed the performance of the best clamp-on sensors. The key feature of the unit is the ability to leave it deployed on the line to record average current readings every 15 minutes for 30+ days. It easily attaches to the line with a standard shotgun style hot-stick. Once on the line, it immediately begins to collect and record the current load on the line.

Resistivity Meters
Periodic compliance checks of ESD work surfaces are super important. Monitors only verify the ground plane, or path to ground. The surface itself can wear down, become dirty, or if you use low quality mat—just not hold up. A handheld Surface Meter is great for running monthly, or prescriptive compliance verification of your ESD surfaces.
