Custom built BM test chamber Environmental test chamber built by JTS Example of one of our test chambers that we may have for hire. James Technical Services Ltd

JTS is one of only a handful of independent UK companies currently manufacturing environmental test chambers. The compact nature of our company enables us to maintain a high degree of flexibility in our manufacturing processes, thus bespoke test chambers are one of our specialities.

Our standard range of test chambers includes bench top and floor standing models, across temperatures ranging between -65°C and +150°C (from -80°C to +300°C for specific applications), and humidities between 10% and 98% RH.

In addition to our standard machines we design and built a number of chambers for environmental testing:

TemperatureTesting Temperature Humidity Testing Ultra Low Temperature Chests Cryogenic Storage Heat treatment plant Walk-in rooms High Temperature Ovens Dust Ingress Chambers Climatic Chamber With Vibration Port Chambers With Rapid Rates Of Temperature Change Large Scale Refrigeration Plant Systems Altitude Test Chambers. Shock Testing Halt Testing Whether your specific requirements lie in the design or the operational capabilities of the test chamber, we will do everything we can to accommodate them.

We work closely with our customers throughout the design and manufacture processes, and provide a full maintenance and calibration service beyond that. We operate a call-out repair service, and can provide a tailor-made service contract - whatever the type of test chamber or refrigeration system.

We work with clients from many sectors, including the electronics, automotive, defence and oil industries.
