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.

Resistance Tester
KT-2000RD
This equipment represents the wanted resistance value in digital figures and at the same time, is an ohmmeter which decides products to be bad in case of being out of the previously set range of H,L and to be good in case of being within the range. Moreover, because it is designed and manufactured on the basis of KAST's business experiences and know-hows accumulated through on-the-spot works for a long time, it is highly trustable, especially strong to noise and impulse that occur on the bad electric condition of on-the-spot or on the connection with any other equipments, and also is convenient for use.
