About ETI
ETI, whose full name is Electronic Temperature Instruments, is a British manufacturer and distributor of thermometers and measurement gear, based in Worthing and established in 1983. Its range covers digital thermometers and related instruments, among them food temperature probes, infrared thermometers, moisture meters and laboratory thermometers, and a good share of the production work is done in Britain. Buyers in food safety, HVAC and healthcare rely on the tools for watching temperature and humidity, and data loggers and temperature sensors sit alongside that range. ETI also runs calibration services and has picked up several accolades for its innovation and its adherence to industry standards.
Instruments like these matter because food has to be cooked and stored at safe temperatures, heating and cooling plant has to run as it should, and laboratory or clinical conditions have to stay inside set limits, so accuracy is central to what the products do.
Payment at ETI can be made with Visa, Mastercard or American Express. Standard and next-day delivery comes free on UK mainland orders over £50 excluding VAT, while smaller orders pay a £6.50 shipping fee for standard delivery. Unused products can be sent back within 30 days of purchase, and refunds reach the original form of payment within 14 days once the goods have been inspected; the original shipping charges are not returned unless the return results from an ETI error. ETI also keeps Facebook, Twitter, YouTube, Instagram and LinkedIn accounts, and shoppers who join the newsletter may hear about discounts on a first order.
