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.

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.

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.

AC Moving Iron Meter
-
Moving-iron instruments are generally used to measure alternating voltages and currents. In moving-iron instruments the movable system consists of one or more pieces of specially-shaped soft iron, which are so pivoted as to be acted upon by the magnetic field produced by the current in coil.
