As a dominant supplier of digital thermometers and temperature sensors, to both the industrial and catering sectors, ETI has developed a reputation throughout Europe and increasingly worldwide, as a leading manufacturer and supplier of quality and value for money instrumentation for a wide range of applications. The business is supported by a full after-sales repairs and calibration service, with in-house UKAS certification facilities.



Queen's Award LogoETI was honoured with a Queens Award for International Trade in 2012 and more recently in 2014.  The company has also been recognised locally by being awarded “Overall Business of The Year” in 2013 and again in 2014 at the Adur & Worthing Business Awards. In 2012 the company won overall “Business of the Year” at the Southern Business Awards.

In 2009 the Thermapen thermometer was awarded - runner-up in the "Best new product" category at the prestigious SOFHT (Society of Food Hygiene & Technology) Awards.
