James Technical Services Ltd specialises in the manufacture of standard and bespoke environmental test chambers. Our extensive experience within the industry gives us a high degree of flexibility in our manufacturing processes, which means that we can produce customised test chambers in line with virtually any requirement. Our standard range covers both bench top and floor standing models, with testing temperatures ranging from -65 ° C to +150 ° C, and humidity levels between 10% and 98% RH. As well as temperature and humidity testing chambers, we also design, develop and manufacture ultra-low temperature chests, high temperature ovens, walk-in environmental test chambers, dust ingress chambers, and climatic chambers. James Technical Services also provide comprehensive maintenance and calibration services to ensure the reliability and longevity of your test equipment. These can be tailored around your requirements. To find out more about the products and services that we offer, visit www.jts-test-chambers.co.uk or get in touch directly on 01874 711 209.

Standard Range Chambers - Visit our website

James Technical Services offers a complete range of competitively priced standard temperature and humidity chambers and ovens. This includes both bench top and floor standing models, each with a range of optional extras available. All models include an access port, temperature/humidity controller, R232 interface and internal shelf. Our standard chambers are built to order, which means that we can easily accommodate variations in the design and running capability. You can find out more about sizes and specifications by visiting the James Technical Services website.

Customised Environmental Test Chambers - Visit our website

James Technical Services design and develop bespoke built environmental test chambers for clients operating in various industries, including electronics, automotive, defence and oil. Flexible manufacturing methods enable us to build one-off chambers to suit virtually any testing requirement, so get in touch with your enquiry and we'll get the ball rolling.

Used Test Chambers - Visit our website

As well as supplying a range of new equipment, JTS is able to offer a range of second hand chambers which can be fully refurbished according to your requirements. 

All of our second hand environmental test chambers come with a 3-month parts and labour warranty as standard.

Calibration - Visit our website

We can carry out calibration on all makes of climatic test chambers.  Our expert and knowledgeable engineers provide calibration that conforms with national standards, either as a part of our service contract or as one-off events.  We would recommend that calibration is carried out either annually or bi-annually, depending on individual circumstances.  We offer a multi-point calibration service, as calibration is only valid at the point at which the measurement was taken.  We therefore standardly use nine points, although this may vary.  Once calibration is satisfactorily completed, a Certificate of Calibration is issued.  Please visit our website for details regarding calibration perimeters and the equipment we utilise to give accurate and reliable data.

Existing Chamber Refurbishments - Visit our website

When you need a replacement test chamber it isn’t always possible to buy one.  If your requirements have outgrown the capability of your existing test chamber, it could be worthwhile considering refurbishment, rather than purchase.  We have a team of experienced engineers who are adept at improving older test chambers and extending their useful life through upgrades or complete refurbishment.  There are a variety of options available and you can see some of those detailed on our website and you can contact us for advice and recommendations.

Spare Parts - Visit our website

We understand that sometimes it can be cheaper and more convenient to repair a machine rather than replacing it outright. It is for this reason that we stock an extensive range of spare parts. It is worth noting that all of our spare parts are fully tested prior to being sold but are not supplied with a warranty. Customers can visit the website to view the full range of parts we have to offer. If you can't find what you're looking for don't worry, just contact us directly and we may be able to help.

Breakdown Callouts - Visit our website

We can offer breakdown callout services for all of our customers, whether you have a service contract or not. We can even respond to breakdown callouts for chambers which are not manufactured by JTS. If you have a problem with your chamber you can contact us and an engineer will attempt to help you over the phone if they can. If the problem requires a visit in person then we will come out to you, diagnose the problem and provide you with a quote for the parts and labour which is required to fix the problem. 

Hire - Visit our website

As well as offering chambers for purchases, customers can opt to hire chambers instead. It is worth noting that when hiring our chambers, customers are required to agree to an initial 4 week period after which they can renew or end their lease on a week to week basis. If you are looking for a particularly long rental period then we may be able to offer you a discount. For further information on this service, don't hesitate to visit to get in touch with us, either by phone or email. 

Service Contracts - Visit our website

Like any piece of machinery, an environmental test chamber needs to be regularly and professionally serviced in order to keep it in top condition and to ensure that it continues to perform as you expect it to. There are also legal reasons for having your equipment serviced: in order to comply with FGAS regulations, any chamber which contains more than 3kg of refrigerant must be checked on an annual basis. Checks for gas leaks must also be made if you are to comply with EC legislation. 


JTS offers a solution to all servicing requirements. We offer contracts that are tailored to your needs and your budget. These can include:

  • One or two scheduled service visits per year.
  • 24-hour call out service.
  • Equipment calibration.
  • Provision of parts.
  • Limited or unlimited breakdown visits.
