About Us | JTS Test Chambers

Operating from a modern purpose built factory unit in the small market town of Talgarth in beautiful Mid Wales, we pride ourselves on building environmental test chambers to high standards and in working closely with clients to ensure their chamber meets with their requirements.

  • Made in Wales, our suppliers are British wherever possible.
  • We manufacture to required standards, constantly improving and developing the way we work, and in our approach to design, to keep pace with changing industries and technologies.
  • Our test chambers are built to last, with systems designed to be adaptable and flexible over the lifetime of the chamber.
  • We provide ongoing training for staff, to ensure compliance with new standards and regulations, and for personal development.
  • We are an equal opportunities employer, and have a family flexible approach, whilst maintaining high standards of manufacturing.



James Technical Services was formed by Glen James in 1995, building on his extensive experience to that date of working for various environmental test chamber manufacturers, including what was Fisons Scientific Apparatus, Pern, and Advanced Climatic Engineering.

In 1985 he co-founded Design Environmental Ltd (now part of Weiss Technik) with John Ticehurst, taking charge of design and build.

After relocating Design Environmental from Kent to Wales in 1989 and working to establish it as a foremost manufacturer of test chambers, Glen left in 1995 to start his own company. Over the years, JTS has established a strong manufacturing base specialising in bespoke/custom test equipment solutions, always putting the customers' needs first to ensure the right solution for the requirement.
