4-Wire Resistance Measurement | Continuity & HiPot Cable & Wire Harness Testers
An add-on option for the CableEye HVX high voltage cable tester series that permits expanded testing for contact and wire resistance as low as 1 mΩ. After checking for opens, shorts, miswires, and resistance limits, the 4-wire Kelvin measurement applies a user-selectable test current from 10 mA to 1 A to determine connection resistance within 1 mΩ. The resistance profile of a model cable may be stored and used as a basis of comparison during later testing to reveal cold solder joints, faulty cri...show more -

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.

AC Rectifier Type Coil Meter
measures the alternating voltage and current with the help of rectifying elements and permanent magnet moving coil type of instruments. However the primary function of rectifier type of instruments work as voltmeter. Now one question must arises in our mind why we use rectifier type of instruments widely in the industrial world though we have various other AC voltmeter like electrodynamometer type instruments, thermocouple type instruments etc? The answer to this question is very simple and is written as follows.
