History of the Thermapen
The Thermapen was introduced in 1992. The original invention of the Thermapen was by Electronic Temperature Instruments Limited (ETI, Ltd.) of Worthing, England. Each subsequent version of the product has been engineered and manufactured by ETI, Ltd.
Thermapen was the first thermocouple thermometer designed for commercial and home kitchens. Prior to that time all other thermocouple thermometers were designed for science and industry; and were much larger, handheld devices with separate probes. These were generally priced at about $200 or more (after purchasing a probe). Keep in mind that’s in pre-1992 dollars.
