About Us


How long have you been in business?

ITIUK was incorporated in 1986, but our history dates back to 1867, making us one of the oldest and most experienced instrumentation companies in the world. The knowledge that we have developed over these years allows us the ability to find the solution to the most complex applications. This is helped by the fact that we manufacturer in-house in Oldham, Gtr. Manchester.

What do you manufacture?

We make Dial Thermometers, Pressure Gauges, Digital Thermometers, Chemical Seals, e-Gauge, Temperature Sensors and other specialist instrumentation.

Are you a manufacturer or supplier?

ITIUK is both. We manufacture pressure and temperature instrumentation in-house, but also source a variety of instrumentation through our network of approved vendors – this allows us to oer a complete supply package to our customers.

Can you export?

Whilst our core business has been built and developed in the domestic market, ITIUK has a strong focus on developing our international presence – we are doing so by appointing strategic partners in countries all over the world.

If you’re interested in becoming a strategic partner then please email to register your interest.

What items do you stock?

We stock a wide range of pressure instrumentation, mainly pressure gauges and diaphragm seals (including flanged, screwed and hygienic).

Our bimetallic and gas-actuated thermometers are manufactured in-house, so, rather than holding stock we manufacture to your exact requirements as and when you need.

What is your turnaround time for calibrations?

Our trained and experienced mechanical and electrical technicians carry out our ISO 9001:2015 repair and calibration service at our custom built facility in Oldham, Greater Manchester, this allows us to work quickly.

Generally we say 3 – 5 working days, however we’re flexible and we carry out our work to suit your needs – this means that quicker (even same day) calibrations are available upon request

What about UKAS and ISO?

We are ISO 9001:2015 accredited and all our Certificates show full traceability to UKAS and therefore should be acceptable to any auditor. If required, UKAS Certification can be provided via one of our partner laboratories.
