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.

Deformation Resistance
Physical properties of paint and coatings play an important role in the quality control. Depending on the application a coating is supposed to be extremely hard and rigid such as for example the coating on the hull of an ice-breaker. Automotive coatings however require a certain flexibility since the thin sheet metal of a car body is not fully rigid ...

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.
