Latest Reviews

TJ Williams Ltd

For many years Kobold Instruments Ltd (UK) have enjoyed a very respectful and cohesive working relationship with TJ Williams Ltd. Their knowledge and expertise regarding pressure related level gauge instrumentation goes back many generations so has always been appreciated by Kobold UK. In particular their experience and expertise with system filled pressure instruments was a key consideration in our decision to appoint TJ Williams Ltd as an official Kobold Distributor. Kobold distributors are rare, but with TJ Williams Ltd we consider them also a valued Technical Solution Provider. As well as technical sales, with our instruments they are able to offer from their factory a variety of unique added value solutions with their process fittings and systems. From Kobold UK’s prospective this enables our standard products to be supplied in the UK from stock with added engineering, and competitively priced. This provides all concerned with valued service.

I wish all suppliers were as easy to deal with as TJW. Such a friendly, competent and helpful team, nothing is too much trouble. John [Cox, sales manager] is extremely helpful and very technical, always interpreting my requirements to ensure I get the right product. My orders are always accurate and on time, a pleasure to deal with.
